:mod:`datetime` --- Basic date and time types
=============================================

:synopsis: Basic date and time types.

2007-08-15 11:28:22 -03:00
The :mod:`datetime` module supplies classes for manipulating dates and times in
both simple and complex ways. While date and time arithmetic is supported, the
focus of the implementation is on efficient attribute extraction for output
2012-05-14 23:17:23 -03:00
formatting and manipulation. For related functionality, see also the
:mod:`time` and :mod:`calendar` modules.
2007-08-15 11:28:22 -03:00
There are two kinds of date and time objects: "naive" and "aware".
An aware object has sufficient knowledge of applicable algorithmic and
political time adjustments, such as time zone and daylight saving time
information, to locate itself relative to other aware objects. An aware object
is used to represent a specific moment in time that is not open to
interpretation [#]_.
A naive object does not contain enough information to unambiguously locate
itself relative to other date/time objects. Whether a naive object represents
2012-05-14 23:17:23 -03:00
Coordinated Universal Time (UTC), local time, or time in some other timezone is
purely up to the program, just like it is up to the program whether a
particular number represents metres, miles, or mass. Naive objects are easy to
understand and to work with, at the cost of ignoring some aspects of reality.
For applications requiring aware objects, :class:`.datetime` and :class:`.time`
objects have an optional time zone information attribute, :attr:`!tzinfo`, that
2012-05-14 23:17:23 -03:00
can be set to an instance of a subclass of the abstract :class:`tzinfo` class.
These :class:`tzinfo` objects capture information about the offset from UTC
time, the time zone name, and whether Daylight Saving Time is in effect. Note
that only one concrete :class:`tzinfo` class, the :class:`timezone` class, is
supplied by the :mod:`datetime` module. The :class:`timezone` class can
represent simple timezones with fixed offset from UTC, such as UTC itself or
North American EST and EDT timezones. Supporting timezones at deeper levels of
detail is up to the application. The rules for time adjustment across the
world are more political than rational, change frequently, and there is no
standard suitable for every application aside from UTC.
2007-08-15 11:28:22 -03:00
The :mod:`datetime` module exports the following constants:
.. data:: MINYEAR
The smallest year number allowed in a :class:`date` or :class:`.datetime` object.
2007-08-15 11:28:22 -03:00
:const:`MINYEAR` is ``1``.
.. data:: MAXYEAR
The largest year number allowed in a :class:`date` or :class:`.datetime` object.
2007-08-15 11:28:22 -03:00
:const:`MAXYEAR` is ``9999``.
.. seealso::
Module :mod:`calendar`
General calendar related functions.
Module :mod:`time`
Time access and conversions.

2007-08-15 11:28:22 -03:00
A duration expressing the difference between two :class:`date`, :class:`.time`,

.. class:: tzinfo
:noindex:
2007-08-15 11:28:22 -03:00
An abstract base class for time zone information objects. These are used by the
:class:`.datetime` and :class:`.time` classes to provide a customizable notion of
2007-08-15 11:28:22 -03:00
time adjustment (for example, to account for time zone and/or daylight saving
time).
.. class:: timezone
:noindex:
A class that implements the :class:`tzinfo` abstract base class as a
fixed offset from the UTC.
.. versionadded:: 3.2
2007-08-15 11:28:22 -03:00
Objects of these types are immutable.
Objects of the :class:`date` type are always naive.
An object of type :class:`.time` or :class:`.datetime` may be naive or aware.
A :class:`.datetime` object *d* is aware if ``d.tzinfo`` is not ``None`` and
``d.tzinfo.utcoffset(d)`` does not return ``None``. If ``d.tzinfo`` is
``None``, or if ``d.tzinfo`` is not ``None`` but ``d.tzinfo.utcoffset(d)``
returns ``None``, *d* is naive. A :class:`.time` object *t* is aware
if ``t.tzinfo`` is not ``None`` and ``t.tzinfo.utcoffset(None)`` does not return
``None``. Otherwise, *t* is naive.
2007-08-15 11:28:22 -03:00
The distinction between naive and aware doesn't apply to :class:`timedelta`
objects.

:class:`timedelta` Objects
--------------------------
A :class:`timedelta` object represents a duration, the difference between two
dates or times.
.. class:: timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0)
2007-08-15 11:28:22 -03:00
All arguments are optional and default to ``0``. Arguments may be integers
2007-08-15 11:28:22 -03:00
or floats, and may be positive or negative.
Only *days*, *seconds* and *microseconds* are stored internally. Arguments are
converted to those units:
* A millisecond is converted to 1000 microseconds.
* A minute is converted to 60 seconds.
* An hour is converted to 3600 seconds.
* A week is converted to 7 days.
and days, seconds and microseconds are then normalized so that the
representation is unique, with
* ``0 <= microseconds < 1000000``
* ``0 <= seconds < 3600*24`` (the number of seconds in one day)
* ``-999999999 <= days <= 999999999``
If any argument is a float and there are fractional microseconds,
the fractional microseconds left over from all arguments are
combined and their sum is rounded to the nearest microsecond using
round-half-to-even tiebreaker. If no argument is a float, the
conversion and normalization processes are exact (no information is
lost).
2007-08-15 11:28:22 -03:00
If the normalized value of days lies outside the indicated range,
:exc:`OverflowError` is raised.

Class attributes are:
2007-08-15 11:28:22 -03:00
.. attribute:: timedelta.min
The most negative :class:`timedelta` object, ``timedelta(-999999999)``.
.. attribute:: timedelta.max
The most positive :class:`timedelta` object, ``timedelta(days=999999999,
hours=23, minutes=59, seconds=59, microseconds=999999)``.
.. attribute:: timedelta.resolution
The smallest possible difference between non-equal :class:`timedelta` objects,
``timedelta(microseconds=1)``.
Note that, because of normalization, ``timedelta.max`` > ``-timedelta.min``.
``-timedelta.max`` is not representable as a :class:`timedelta` object.

Notes:
(1)
This is exact, but may overflow.
(2)
This is exact, and cannot overflow.
(3)
Division by 0 raises :exc:`ZeroDivisionError`.
(4)
-*timedelta.max* is not representable as a :class:`timedelta` object.
(5)
String representations of :class:`timedelta` objects are normalized
similarly to their internal representation. This leads to somewhat
unusual results for negative timedeltas. For example:
>>> timedelta(hours=-5)
datetime.timedelta(-1, 68400)
>>> print(_)
-1 day, 19:00:00
2007-08-15 11:28:22 -03:00
In addition to the operations listed above :class:`timedelta` objects support
certain additions and subtractions with :class:`date` and :class:`.datetime`
2007-08-15 11:28:22 -03:00
objects (see below).
.. versionchanged:: 3.2
Floor division and true division of a :class:`timedelta` object by another
:class:`timedelta` object are now supported, as are remainder operations and
the :func:`divmod` function. True division and multiplication of a
:class:`timedelta` object by a :class:`float` object are now supported.
2007-08-15 11:28:22 -03:00
Comparisons of :class:`timedelta` objects are supported with the
:class:`timedelta` object representing the smaller duration considered to be the
smaller timedelta. In order to stop mixed-type comparisons from falling back to
the default comparison by object address, when a :class:`timedelta` object is
compared to an object of a different type, :exc:`TypeError` is raised unless the
comparison is ``==`` or ``!=``. The latter cases return :const:`False` or
:const:`True`, respectively.

2007-11-02 20:46:40 -03:00
:class:`timedelta` objects are :term:`hashable` (usable as dictionary keys), support
2007-08-15 11:28:22 -03:00
efficient pickling, and in Boolean contexts, a :class:`timedelta` object is
considered to be true if and only if it isn't equal to ``timedelta(0)``.
Instance methods:
.. method:: timedelta.total_seconds()
Return the total number of seconds contained in the duration. Equivalent to
``td / timedelta(seconds=1)``.
Note that for very large time intervals (greater than 270 years on
most platforms) this method will lose microsecond accuracy.

.. _datetime-date:
:class:`date` Objects
---------------------
A :class:`date` object represents a date (year, month and day) in an idealized
calendar, the current Gregorian calendar indefinitely extended in both
directions. January 1 of year 1 is called day number 1, January 2 of year 1 is
called day number 2, and so on. This matches the definition of the "proleptic
Gregorian" calendar in Dershowitz and Reingold's book Calendrical Calculations,
where it's the base calendar for all computations. See the book for algorithms
for converting between proleptic Gregorian ordinals and many other calendar
systems.
.. class:: date(year, month, day)
All arguments are required. Arguments may be integers, in the following
2007-08-15 11:28:22 -03:00
ranges:
* ``MINYEAR <= year <= MAXYEAR``
* ``1 <= month <= 12``
* ``1 <= day <= number of days in the given month and year``
If an argument outside those ranges is given, :exc:`ValueError` is raised.

.. classmethod:: date.fromtimestamp(timestamp)
2007-08-15 11:28:22 -03:00
Return the local date corresponding to the POSIX timestamp, such as is returned
by :func:`time.time`. This may raise :exc:`OverflowError`, if the timestamp is out
of the range of values supported by the platform C :c:func:`localtime` function,
and :exc:`OSError` on :c:func:`localtime` failure.
2007-08-15 11:28:22 -03:00
It's common for this to be restricted to years from 1970 through 2038. Note
that on non-POSIX systems that include leap seconds in their notion of a
timestamp, leap seconds are ignored by :meth:`fromtimestamp`.
.. versionchanged:: 3.3
Raise :exc:`OverflowError` instead of :exc:`ValueError` if the timestamp
is out of the range of values supported by the platform C
:c:func:`localtime` function. Raise :exc:`OSError` instead of
:exc:`ValueError` on :c:func:`localtime` failure.

Supported operations:
+-------------------------------+----------------------------------------------+
| Operation | Result |
+===============================+==============================================+
| ``date2 = date1 + timedelta`` | *date2* is ``timedelta.days`` days removed |
| | from *date1*. (1) |
+-------------------------------+----------------------------------------------+
| ``date2 = date1 - timedelta`` | Computes *date2* such that ``date2 + |
| | timedelta == date1``. (2) |
+-------------------------------+----------------------------------------------+
| ``timedelta = date1 - date2`` | \(3) |
+-------------------------------+----------------------------------------------+
| ``date1 < date2`` | *date1* is considered less than *date2* when |
| | *date1* precedes *date2* in time. (4) |
+-------------------------------+----------------------------------------------+
Notes:
(1)
*date2* is moved forward in time if ``timedelta.days > 0``, or backward if
``timedelta.days < 0``. Afterward ``date2 - date1 == timedelta.days``.
``timedelta.seconds`` and ``timedelta.microseconds`` are ignored.
:exc:`OverflowError` is raised if ``date2.year`` would be smaller than
:const:`MINYEAR` or larger than :const:`MAXYEAR`.
(2)
This isn't quite equivalent to date1 + (-timedelta), because -timedelta in
isolation can overflow in cases where date1 - timedelta does not.
``timedelta.seconds`` and ``timedelta.microseconds`` are ignored.
(3)
This is exact, and cannot overflow. timedelta.seconds and
timedelta.microseconds are 0, and date2 + timedelta == date1 after.
(4)
In other words, ``date1 < date2`` if and only if ``date1.toordinal() <
date2.toordinal()``. In order to stop comparison from falling back to the
default scheme of comparing object addresses, date comparison normally raises
:exc:`TypeError` if the other comparand isn't also a :class:`date` object.
However, ``NotImplemented`` is returned instead if the other comparand has a
:meth:`timetuple` attribute. This hook gives other kinds of date objects a
chance at implementing mixed-type comparison. If not, when a :class:`date`
object is compared to an object of a different type, :exc:`TypeError` is raised
unless the comparison is ``==`` or ``!=``. The latter cases return
:const:`False` or :const:`True`, respectively.
Dates can be used as dictionary keys. In Boolean contexts, all :class:`date`
objects are considered to be true.
Instance methods:
.. method:: date.replace(year=self.year, month=self.month, day=self.day)
2007-08-15 11:28:22 -03:00
Return a date with the same value, except for those parameters given new
values by whichever keyword arguments are specified. For example, if ``d ==
date(2002, 12, 31)``, then ``d.replace(day=26) == date(2002, 12, 26)``.
2007-08-15 11:28:22 -03:00
.. method:: date.timetuple()
Return a :class:`time.struct_time` such as returned by :func:`time.localtime`.
The hours, minutes and seconds are 0, and the DST flag is -1. ``d.timetuple()``
is equivalent to ``time.struct_time((d.year, d.month, d.day, 0, 0, 0,
d.weekday(), yday, -1))``, where ``yday = d.toordinal() - date(d.year, 1,
1).toordinal() + 1`` is the day number within the current year starting with
``1`` for January 1st.
2007-08-15 11:28:22 -03:00
.. method:: date.toordinal()
Return the proleptic Gregorian ordinal of the date, where January 1 of year 1
has ordinal 1. For any :class:`date` object *d*,
``date.fromordinal(d.toordinal()) == d``.
.. method:: date.weekday()
Return the day of the week as an integer, where Monday is 0 and Sunday is 6.
For example, ``date(2002, 12, 4).weekday() == 2``, a Wednesday. See also
:meth:`isoweekday`.
.. method:: date.isoweekday()
Return the day of the week as an integer, where Monday is 1 and Sunday is 7.
For example, ``date(2002, 12, 4).isoweekday() == 3``, a Wednesday. See also
:meth:`weekday`, :meth:`isocalendar`.
.. method:: date.isocalendar()
Return a 3-tuple, (ISO year, ISO week number, ISO weekday).
The ISO calendar is a widely used variant of the Gregorian calendar. See
https://www.staff.science.uu.nl/~gent0113/calendar/isocalendar.htm for a good
explanation.
2007-08-15 11:28:22 -03:00
The ISO year consists of 52 or 53 full weeks, and where a week starts on a
Monday and ends on a Sunday. The first week of an ISO year is the first
(Gregorian) calendar week of a year containing a Thursday. This is called week
number 1, and the ISO year of that Thursday is the same as its Gregorian year.
For example, 2004 begins on a Thursday, so the first week of ISO year 2004
begins on Monday, 29 Dec 2003 and ends on Sunday, 4 Jan 2004, so that
``date(2003, 12, 29).isocalendar() == (2004, 1, 1)`` and ``date(2004, 1,
4).isocalendar() == (2004, 1, 7)``.
.. method:: date.isoformat()
Return a string representing the date in ISO 8601 format, 'YYYY-MM-DD'. For
example, ``date(2002, 12, 4).isoformat() == '2002-12-04'``.
.. method:: date.__str__()
For a date *d*, ``str(d)`` is equivalent to ``d.isoformat()``.
.. method:: date.ctime()
Return a string representing the date, for example ``date(2002, 12,
4).ctime() == 'Wed Dec 4 00:00:00 2002'``. ``d.ctime()`` is equivalent to
``time.ctime(time.mktime(d.timetuple()))`` on platforms where the native C
:c:func:`ctime` function (which :func:`time.ctime` invokes, but which
2007-08-15 11:28:22 -03:00
:meth:`date.ctime` does not invoke) conforms to the C standard.
.. method:: date.strftime(format)
Return a string representing the date, controlled by an explicit format string.
Format codes referring to hours, minutes or seconds will see 0 values. For a
complete list of formatting directives, see
:ref:`strftime-strptime-behavior`.

:class:`.datetime` Objects
--------------------------
2007-08-15 11:28:22 -03:00
A :class:`.datetime` object is a single object containing all the information
from a :class:`date` object and a :class:`.time` object. Like a :class:`date`
object, :class:`.datetime` assumes the current Gregorian calendar extended in
both directions; like a time object, :class:`.datetime` assumes there are exactly
2007-08-15 11:28:22 -03:00
3600\*24 seconds in every day.
Constructor:
.. class:: datetime(year, month, day, hour=0, minute=0, second=0, microsecond=0, tzinfo=None, *, fold=0)
2007-08-15 11:28:22 -03:00
The year, month and day arguments are required. *tzinfo* may be ``None``, or an
instance of a :class:`tzinfo` subclass. The remaining arguments may be integers,
in the following ranges:
2007-08-15 11:28:22 -03:00
* ``MINYEAR <= year <= MAXYEAR``,
* ``1 <= month <= 12``,
* ``1 <= day <= number of days in the given month and year``,
* ``0 <= hour < 24``,
* ``0 <= minute < 60``,
* ``0 <= second < 60``,
* ``0 <= microsecond < 1000000``,
* ``fold in [0, 1]``.
2007-08-15 11:28:22 -03:00
If an argument outside those ranges is given, :exc:`ValueError` is raised.
.. versionadded:: 3.6
Added the ``fold`` argument.

.. classmethod:: datetime.now(tz=None)
2007-08-15 11:28:22 -03:00
Return the current local date and time. If optional argument *tz* is ``None``
or not specified, this is like :meth:`today`, but, if possible, supplies more
precision than can be gotten from going through a :func:`time.time` timestamp
(for example, this may be possible on platforms supplying the C
:c:func:`gettimeofday` function).
2007-08-15 11:28:22 -03:00
If *tz* is not ``None``, it must be an instance of a :class:`tzinfo` subclass, and the
current date and time are converted to *tz*s time zone. In this case the
2007-08-15 11:28:22 -03:00
result is equivalent to ``tz.fromutc(datetime.utcnow().replace(tzinfo=tz))``.
See also :meth:`today`, :meth:`utcnow`.

.. classmethod:: datetime.fromtimestamp(timestamp, tz=None)
2007-08-15 11:28:22 -03:00
Return the local date and time corresponding to the POSIX timestamp, such as is
returned by :func:`time.time`. If optional argument *tz* is ``None`` or not
specified, the timestamp is converted to the platform's local date and time, and
the returned :class:`.datetime` object is naive.
2007-08-15 11:28:22 -03:00
If *tz* is not ``None``, it must be an instance of a :class:`tzinfo` subclass, and the
timestamp is converted to *tz*s time zone. In this case the result is
2007-08-15 11:28:22 -03:00
equivalent to
``tz.fromutc(datetime.utcfromtimestamp(timestamp).replace(tzinfo=tz))``.
:meth:`fromtimestamp` may raise :exc:`OverflowError`, if the timestamp is out of
the range of values supported by the platform C :c:func:`localtime` or
:c:func:`gmtime` functions, and :exc:`OSError` on :c:func:`localtime` or
:c:func:`gmtime` failure.
It's common for this to be restricted to years in
2007-08-15 11:28:22 -03:00
1970 through 2038. Note that on non-POSIX systems that include leap seconds in
their notion of a timestamp, leap seconds are ignored by :meth:`fromtimestamp`,
and then it's possible to have two timestamps differing by a second that yield
identical :class:`.datetime` objects. See also :meth:`utcfromtimestamp`.
2007-08-15 11:28:22 -03:00
.. versionchanged:: 3.3
Raise :exc:`OverflowError` instead of :exc:`ValueError` if the timestamp
is out of the range of values supported by the platform C
:c:func:`localtime` or :c:func:`gmtime` functions. Raise :exc:`OSError`
instead of :exc:`ValueError` on :c:func:`localtime` or :c:func:`gmtime`
failure.
.. versionchanged:: 3.6
:meth:`fromtimestamp` may return instances with :attr:`.fold` set to 1.

.. classmethod:: datetime.utcfromtimestamp(timestamp)
2007-08-15 11:28:22 -03:00
Return the UTC :class:`.datetime` corresponding to the POSIX timestamp, with
:attr:`.tzinfo` ``None``. This may raise :exc:`OverflowError`, if the timestamp is
out of the range of values supported by the platform C :c:func:`gmtime` function,
and :exc:`OSError` on :c:func:`gmtime` failure.
It's common for this to be restricted to years in 1970 through 2038.
To get an aware :class:`.datetime` object, call :meth:`fromtimestamp`::
datetime.fromtimestamp(timestamp, timezone.utc)
On the POSIX compliant platforms, it is equivalent to the following
expression::
2007-08-15 11:28:22 -03:00
datetime(1970, 1, 1, tzinfo=timezone.utc) + timedelta(seconds=timestamp)
except the latter formula always supports the full years range: between
:const:`MINYEAR` and :const:`MAXYEAR` inclusive.
.. versionchanged:: 3.3
Raise :exc:`OverflowError` instead of :exc:`ValueError` if the timestamp
is out of the range of values supported by the platform C
:c:func:`gmtime` function. Raise :exc:`OSError` instead of
:exc:`ValueError` on :c:func:`gmtime` failure.

.. attribute:: datetime.fold
In ``[0, 1]``. Used to disambiguate wall times during a repeated interval. (A
repeated interval occurs when clocks are rolled back at the end of daylight saving
time or when the UTC offset for the current zone is decreased for political reasons.)
The value 0 (1) represents the earlier (later) of the two moments with the same wall
time representation.

| | :class:`.datetime`. (4) |
+---------------------------------------+--------------------------------+
2007-08-15 11:28:22 -03:00
(1)
datetime2 is a duration of timedelta removed from datetime1, moving forward in
time if ``timedelta.days`` > 0, or backward if ``timedelta.days`` < 0. The
result has the same :attr:`~.datetime.tzinfo` attribute as the input datetime, and
datetime2 - datetime1 == timedelta after. :exc:`OverflowError` is raised if
datetime2.year would be smaller than :const:`MINYEAR` or larger than
:const:`MAXYEAR`. Note that no time zone adjustments are done even if the
input is an aware object.
2007-08-15 11:28:22 -03:00
(2)
Computes the datetime2 such that datetime2 + timedelta == datetime1. As for
addition, the result has the same :attr:`~.datetime.tzinfo` attribute as the input
datetime, and no time zone adjustments are done even if the input is aware.
This isn't quite equivalent to datetime1 + (-timedelta), because -timedelta
in isolation can overflow in cases where datetime1 - timedelta does not.
2007-08-15 11:28:22 -03:00
(3)
Subtraction of a :class:`.datetime` from a :class:`.datetime` is defined only if
2007-08-15 11:28:22 -03:00
both operands are naive, or if both are aware. If one is aware and the other is
naive, :exc:`TypeError` is raised.
If both are naive, or both are aware and have the same :attr:`~.datetime.tzinfo` attribute,
the :attr:`~.datetime.tzinfo` attributes are ignored, and the result is a :class:`timedelta`
2007-08-15 11:28:22 -03:00
object *t* such that ``datetime2 + t == datetime1``. No time zone adjustments
are done in this case.
If both are aware and have different :attr:`~.datetime.tzinfo` attributes, ``a-b`` acts
as if *a* and *b* were first converted to naive UTC datetimes first. The
result is ``(a.replace(tzinfo=None) - a.utcoffset()) - (b.replace(tzinfo=None)
- b.utcoffset())`` except that the implementation never overflows.
2007-08-15 11:28:22 -03:00
(4)
*datetime1* is considered less than *datetime2* when *datetime1* precedes
*datetime2* in time.
If one comparand is naive and the other is aware, :exc:`TypeError`
is raised if an order comparison is attempted. For equality
comparisons, naive instances are never equal to aware instances.
If both comparands are aware, and have the same :attr:`~.datetime.tzinfo` attribute, the
common :attr:`~.datetime.tzinfo` attribute is ignored and the base datetimes are
compared. If both comparands are aware and have different :attr:`~.datetime.tzinfo`
attributes, the comparands are first adjusted by subtracting their UTC
offsets (obtained from ``self.utcoffset()``).
2007-08-15 11:28:22 -03:00
.. versionchanged:: 3.3
Equality comparisons between naive and aware :class:`.datetime`
2012-06-24 17:22:09 -03:00
instances don't raise :exc:`TypeError`.
2007-08-15 11:28:22 -03:00
.. note::
In order to stop comparison from falling back to the default scheme of comparing
object addresses, datetime comparison normally raises :exc:`TypeError` if the
other comparand isn't also a :class:`.datetime` object. However,
2007-08-15 11:28:22 -03:00
``NotImplemented`` is returned instead if the other comparand has a
:meth:`timetuple` attribute. This hook gives other kinds of date objects a
chance at implementing mixed-type comparison. If not, when a :class:`.datetime`
2007-08-15 11:28:22 -03:00
object is compared to an object of a different type, :exc:`TypeError` is raised
unless the comparison is ``==`` or ``!=``. The latter cases return
:const:`False` or :const:`True`, respectively.
:class:`.datetime` objects can be used as dictionary keys. In Boolean contexts,
all :class:`.datetime` objects are considered to be true.
2007-08-15 11:28:22 -03:00
Instance methods:
.. method:: datetime.date()
Return :class:`date` object with same year, month and day.
.. method:: datetime.time()
Return :class:`.time` object with same hour, minute, second, microsecond and fold.
:attr:`.tzinfo` is ``None``. See also method :meth:`timetz`.
2007-08-15 11:28:22 -03:00
.. versionchanged:: 3.6
The fold value is copied to the returned :class:`.time` object.
2007-08-15 11:28:22 -03:00
.. method:: datetime.timetz()
Return :class:`.time` object with same hour, minute, second, microsecond, fold, and
tzinfo attributes. See also method :meth:`time`.
2007-08-15 11:28:22 -03:00
.. versionchanged:: 3.6
The fold value is copied to the returned :class:`.time` object.
2007-08-15 11:28:22 -03:00
.. method:: datetime.replace(year=self.year, month=self.month, day=self.day, \
hour=self.hour, minute=self.minute, second=self.second, microsecond=self.microsecond, \
tzinfo=self.tzinfo, * fold=0)
2007-08-15 11:28:22 -03:00
Return a datetime with the same attributes, except for those attributes given
new values by whichever keyword arguments are specified. Note that
``tzinfo=None`` can be specified to create a naive datetime from an aware
datetime with no conversion of date and time data.
2007-08-15 11:28:22 -03:00
.. versionadded:: 3.6
Added the ``fold`` argument.
2007-08-15 11:28:22 -03:00
.. method:: datetime.astimezone(tz=None)
2007-08-15 11:28:22 -03:00
Return a :class:`.datetime` object with new :attr:`.tzinfo` attribute *tz*,
adjusting the date and time data so the result is the same UTC time as
*self*, but in *tz*'s local time.
2007-08-15 11:28:22 -03:00
If provided, *tz* must be an instance of a :class:`tzinfo` subclass, and its
:meth:`utcoffset` and :meth:`dst` methods must not return ``None``. If *self*
is naive (``self.tzinfo is None``), it is presumed to represent time in the
system timezone.
2007-08-15 11:28:22 -03:00
If called without arguments (or with ``tz=None``) the system local
timezone is assumed for the target timezone. The ``.tzinfo`` attribute of the converted
datetime instance will be set to an instance of :class:`timezone`
with the zone name and offset obtained from the OS.
2007-08-15 11:28:22 -03:00
If ``self.tzinfo`` is *tz*, ``self.astimezone(tz)`` is equal to *self*: no
adjustment of date or time data is performed. Else the result is local
time in the timezone *tz*, representing the same UTC time as *self*: after
``astz = dt.astimezone(tz)``, ``astz - astz.utcoffset()`` will have
the same date and time data as ``dt - dt.utcoffset()``.
2007-08-15 11:28:22 -03:00
If you merely want to attach a time zone object *tz* to a datetime *dt* without
adjustment of date and time data, use ``dt.replace(tzinfo=tz)``. If you
2007-08-15 11:28:22 -03:00
merely want to remove the time zone object from an aware datetime *dt* without
conversion of date and time data, use ``dt.replace(tzinfo=None)``.
2007-08-15 11:28:22 -03:00
Note that the default :meth:`tzinfo.fromutc` method can be overridden in a
:class:`tzinfo` subclass to affect the result returned by :meth:`astimezone`.
Ignoring error cases, :meth:`astimezone` acts like::
def astimezone(self, tz):
if self.tzinfo is tz:
return self
# Convert self to UTC, and attach the new time zone object.
utc = (self - self.utcoffset()).replace(tzinfo=tz)
# Convert from UTC to tz's local time.
return tz.fromutc(utc)
.. versionchanged:: 3.3
*tz* now can be omitted.
.. versionchanged:: 3.6
The :meth:`astimezone` method can now be called on naive instances that
are presumed to represent system local time.
2007-08-15 11:28:22 -03:00
.. method:: datetime.utcoffset()
If :attr:`.tzinfo` is ``None``, returns ``None``, else returns
2007-08-15 11:28:22 -03:00
``self.tzinfo.utcoffset(self)``, and raises an exception if the latter doesn't
return ``None``, or a :class:`timedelta` object representing a whole number of
minutes with magnitude less than one day.
.. method:: datetime.dst()
If :attr:`.tzinfo` is ``None``, returns ``None``, else returns
2007-08-15 11:28:22 -03:00
``self.tzinfo.dst(self)``, and raises an exception if the latter doesn't return
``None``, or a :class:`timedelta` object representing a whole number of minutes
with magnitude less than one day.
.. method:: datetime.tzname()
If :attr:`.tzinfo` is ``None``, returns ``None``, else returns
2007-08-15 11:28:22 -03:00
``self.tzinfo.tzname(self)``, raises an exception if the latter doesn't return
``None`` or a string object,
.. method:: datetime.timetuple()
Return a :class:`time.struct_time` such as returned by :func:`time.localtime`.
``d.timetuple()`` is equivalent to ``time.struct_time((d.year, d.month, d.day,
d.hour, d.minute, d.second, d.weekday(), yday, dst))``, where ``yday =
d.toordinal() - date(d.year, 1, 1).toordinal() + 1`` is the day number within
the current year starting with ``1`` for January 1st. The :attr:`tm_isdst` flag
of the result is set according to the :meth:`dst` method: :attr:`.tzinfo` is
2010-10-06 07:26:05 -03:00
``None`` or :meth:`dst` returns ``None``, :attr:`tm_isdst` is set to ``-1``;
else if :meth:`dst` returns a non-zero value, :attr:`tm_isdst` is set to ``1``;
else :attr:`tm_isdst` is set to ``0``.
2007-08-15 11:28:22 -03:00
.. method:: datetime.utctimetuple()
If :class:`.datetime` instance *d* is naive, this is the same as
2007-08-15 11:28:22 -03:00
``d.timetuple()`` except that :attr:`tm_isdst` is forced to 0 regardless of what
``d.dst()`` returns. DST is never in effect for a UTC time.
If *d* is aware, *d* is normalized to UTC time, by subtracting
``d.utcoffset()``, and a :class:`time.struct_time` for the
normalized time is returned. :attr:`tm_isdst` is forced to 0. Note
that an :exc:`OverflowError` may be raised if *d*.year was
``MINYEAR`` or ``MAXYEAR`` and UTC adjustment spills over a year
2007-08-15 11:28:22 -03:00
boundary.
.. method:: datetime.toordinal()
Return the proleptic Gregorian ordinal of the date. The same as
``self.date().toordinal()``.
.. method:: datetime.timestamp()
Return POSIX timestamp corresponding to the :class:`.datetime`
instance. The return value is a :class:`float` similar to that
returned by :func:`time.time`.
Naive :class:`.datetime` instances are assumed to represent local
time and this method relies on the platform C :c:func:`mktime`
function to perform the conversion. Since :class:`.datetime`
supports wider range of values than :c:func:`mktime` on many
platforms, this method may raise :exc:`OverflowError` for times far
in the past or far in the future.
For aware :class:`.datetime` instances, the return value is computed
as::
(dt - datetime(1970, 1, 1, tzinfo=timezone.utc)).total_seconds()
.. versionadded:: 3.3
.. versionchanged:: 3.6
The :meth:`timestamp` method uses the :attr:`.fold` attribute to
disambiguate the times during a repeated interval.
.. note::
There is no method to obtain the POSIX timestamp directly from a
naive :class:`.datetime` instance representing UTC time. If your
application uses this convention and your system timezone is not
set to UTC, you can obtain the POSIX timestamp by supplying
``tzinfo=timezone.utc``::
timestamp = dt.replace(tzinfo=timezone.utc).timestamp()
or by calculating the timestamp directly::
timestamp = (dt - datetime(1970, 1, 1)) / timedelta(seconds=1)
2007-08-15 11:28:22 -03:00
.. method:: datetime.weekday()
Return the day of the week as an integer, where Monday is 0 and Sunday is 6.
The same as ``self.date().weekday()``. See also :meth:`isoweekday`.
.. method:: datetime.isoweekday()
Return the day of the week as an integer, where Monday is 1 and Sunday is 7.
The same as ``self.date().isoweekday()``. See also :meth:`weekday`,
:meth:`isocalendar`.
.. method:: datetime.isocalendar()
Return a 3-tuple, (ISO year, ISO week number, ISO weekday). The same as
``self.date().isocalendar()``.
.. method:: datetime.isoformat(sep='T', timespec='auto')
2007-08-15 11:28:22 -03:00
Return a string representing the date and time in ISO 8601 format,
YYYY-MM-DDTHH:MM:SS.mmmmmm or, if :attr:`microsecond` is 0,
YYYY-MM-DDTHH:MM:SS
If :meth:`utcoffset` does not return ``None``, a 6-character string is
appended, giving the UTC offset in (signed) hours and minutes:
YYYY-MM-DDTHH:MM:SS.mmmmmm+HH:MM or, if :attr:`microsecond` is 0
YYYY-MM-DDTHH:MM:SS+HH:MM

placed between the date and time portions of the result. For example,
2007-08-15 11:28:22 -03:00
>>> from datetime import tzinfo, timedelta, datetime
>>> class TZ(tzinfo):
... def utcoffset(self, dt): return timedelta(minutes=-399)
...
>>> datetime(2002, 12, 25, tzinfo=TZ()).isoformat(' ')
'2002-12-25 00:00:00-06:39'
The optional argument *timespec* specifies the number of additional
components of the time to include (the default is ``'auto'``).
It can be one of the following:
- ``'auto'``: Same as ``'seconds'`` if :attr:`microsecond` is 0,
same as ``'microseconds'`` otherwise.
- ``'hours'``: Include the :attr:`hour` in the two-digit HH format.
- ``'minutes'``: Include :attr:`hour` and :attr:`minute` in HH:MM format.
- ``'seconds'``: Include :attr:`hour`, :attr:`minute`, and :attr:`second`
in HH:MM:SS format.
- ``'milliseconds'``: Include full time, but truncate fractional second
part to milliseconds. HH:MM:SS.sss format.
- ``'microseconds'``: Include full time in HH:MM:SS.mmmmmm format.
.. note::
Excluded time components are truncated, not rounded.
:exc:`ValueError` will be raised on an invalid *timespec* argument.
>>> from datetime import datetime
>>> datetime.now().isoformat(timespec='minutes') # doctest: +SKIP
'2002-12-25T00:00'
>>> dt = datetime(2015, 1, 1, 12, 30, 59, 0)
>>> dt.isoformat(timespec='microseconds')
'2015-01-01T12:30:59.000000'
.. versionadded:: 3.6
Added the *timespec* argument.
2007-08-15 11:28:22 -03:00
.. method:: datetime.__str__()
For a :class:`.datetime` instance *d*, ``str(d)`` is equivalent to
2007-08-15 11:28:22 -03:00
``d.isoformat(' ')``.
.. method:: datetime.ctime()
Return a string representing the date and time, for example ``datetime(2002, 12,
4, 20, 30, 40).ctime() == 'Wed Dec 4 20:30:40 2002'``. ``d.ctime()`` is
equivalent to ``time.ctime(time.mktime(d.timetuple()))`` on platforms where the
native C :c:func:`ctime` function (which :func:`time.ctime` invokes, but which
2007-08-15 11:28:22 -03:00
:meth:`datetime.ctime` does not invoke) conforms to the C standard.
.. method:: datetime.strftime(format)
Return a string representing the date and time, controlled by an explicit format
string. For a complete list of formatting directives, see
:ref:`strftime-strptime-behavior`.

.. _datetime-time:
:class:`.time` Objects
----------------------
2007-08-15 11:28:22 -03:00
A time object represents a (local) time of day, independent of any particular
day, and subject to adjustment via a :class:`tzinfo` object.
.. class:: time(hour=0, minute=0, second=0, microsecond=0, tzinfo=None, *, fold=0)
2007-08-15 11:28:22 -03:00
All arguments are optional. *tzinfo* may be ``None``, or an instance of a
:class:`tzinfo` subclass. The remaining arguments may be integers, in the
2007-08-15 11:28:22 -03:00
following ranges:
* ``0 <= hour < 24``,
* ``0 <= minute < 60``,
* ``0 <= second < 60``,
* ``0 <= microsecond < 1000000``,
* ``fold in [0, 1]``.
2007-08-15 11:28:22 -03:00
If an argument outside those ranges is given, :exc:`ValueError` is raised. All
default to ``0`` except *tzinfo*, which defaults to :const:`None`.
Class attributes:
.. attribute:: time.min
The earliest representable :class:`.time`, ``time(0, 0, 0, 0)``.
2007-08-15 11:28:22 -03:00
.. attribute:: time.max
The latest representable :class:`.time`, ``time(23, 59, 59, 999999)``.
2007-08-15 11:28:22 -03:00
.. attribute:: time.resolution
The smallest possible difference between non-equal :class:`.time` objects,
``timedelta(microseconds=1)``, although note that arithmetic on
:class:`.time` objects is not supported.

.. attribute:: time.fold
In ``[0, 1]``. Used to disambiguate wall times during a repeated interval. (A
repeated interval occurs when clocks are rolled back at the end of daylight saving
time or when the UTC offset for the current zone is decreased for political reasons.)
The value 0 (1) represents the earlier (later) of the two moments with the same wall
time representation.
.. versionadded:: 3.6
2007-08-15 11:28:22 -03:00
Supported operations:
* comparison of :class:`.time` to :class:`.time`, where *a* is considered less
2007-08-15 11:28:22 -03:00
than *b* when *a* precedes *b* in time. If one comparand is naive and the other
is aware, :exc:`TypeError` is raised if an order comparison is attempted. For equality
comparisons, naive instances are never equal to aware instances.
If both comparands are aware, and have
the same :attr:`~time.tzinfo` attribute, the common :attr:`~time.tzinfo` attribute is
ignored and the base times are compared. If both comparands are aware and
have different :attr:`~time.tzinfo` attributes, the comparands are first adjusted by
subtracting their UTC offsets (obtained from ``self.utcoffset()``). In order
to stop mixed-type comparisons from falling back to the default comparison by
object address, when a :class:`.time` object is compared to an object of a
different type, :exc:`TypeError` is raised unless the comparison is ``==`` or
``!=``. The latter cases return :const:`False` or :const:`True`, respectively.
2007-08-15 11:28:22 -03:00
.. versionchanged:: 3.3
Equality comparisons between naive and aware :class:`~datetime.time` instances
2012-06-24 17:22:09 -03:00
don't raise :exc:`TypeError`.
2007-08-15 11:28:22 -03:00
* hash, use as dict key
* efficient pickling
In boolean contexts, a :class:`.time` object is always considered to be true.
2007-08-15 11:28:22 -03:00
.. versionchanged:: 3.5
Before Python 3.5, a :class:`.time` object was considered to be false if it
represented midnight in UTC. This behavior was considered obscure and
error-prone and has been removed in Python 3.5. See :issue:`13936` for full
details.

Instance methods:
2007-08-15 11:28:22 -03:00
.. method:: time.replace(hour=self.hour, minute=self.minute, second=self.second, \
microsecond=self.microsecond, tzinfo=self.tzinfo, * fold=0)
2007-08-15 11:28:22 -03:00
Return a :class:`.time` with the same value, except for those attributes given
new values by whichever keyword arguments are specified. Note that
``tzinfo=None`` can be specified to create a naive :class:`.time` from an
aware :class:`.time`, without conversion of the time data.
2007-08-15 11:28:22 -03:00
.. versionadded:: 3.6
Added the ``fold`` argument.
2007-08-15 11:28:22 -03:00
.. method:: time.isoformat(timespec='auto')
2007-08-15 11:28:22 -03:00
Return a string representing the time in ISO 8601 format, HH:MM:SS.mmmmmm or, if
:attr:`microsecond` is 0, HH:MM:SS If :meth:`utcoffset` does not return ``None``, a
2007-08-15 11:28:22 -03:00
6-character string is appended, giving the UTC offset in (signed) hours and
minutes: HH:MM:SS.mmmmmm+HH:MM or, if self.microsecond is 0, HH:MM:SS+HH:MM
The optional argument *timespec* specifies the number of additional
components of the time to include (the default is ``'auto'``).
It can be one of the following:
- ``'auto'``: Same as ``'seconds'`` if :attr:`microsecond` is 0,
same as ``'microseconds'`` otherwise.
- ``'hours'``: Include the :attr:`hour` in the two-digit HH format.
- ``'minutes'``: Include :attr:`hour` and :attr:`minute` in HH:MM format.
- ``'seconds'``: Include :attr:`hour`, :attr:`minute`, and :attr:`second`
in HH:MM:SS format.
- ``'milliseconds'``: Include full time, but truncate fractional second
part to milliseconds. HH:MM:SS.sss format.
- ``'microseconds'``: Include full time in HH:MM:SS.mmmmmm format.
.. note::
Excluded time components are truncated, not rounded.
:exc:`ValueError` will be raised on an invalid *timespec* argument.
>>> from datetime import time
2016-06-05 01:36:53 -03:00
>>> time(hour=12, minute=34, second=56, microsecond=123456).isoformat(timespec='minutes')
'12:34'
2016-06-05 01:36:53 -03:00
>>> dt = time(hour=12, minute=34, second=56, microsecond=0)
>>> dt.isoformat(timespec='microseconds')
'12:34:56.000000'
>>> dt.isoformat(timespec='auto')
'12:34:56'
.. versionadded:: 3.6
Added the *timespec* argument.
2007-08-15 11:28:22 -03:00
.. method:: time.__str__()
For a time *t*, ``str(t)`` is equivalent to ``t.isoformat()``.
.. method:: time.strftime(format)
Return a string representing the time, controlled by an explicit format
string. For a complete list of formatting directives, see
:ref:`strftime-strptime-behavior`.
2007-08-15 11:28:22 -03:00
.. method:: time.__format__(format)
Same as :meth:`.time.strftime`. This makes it possible to specify a format string
for a :class:`.time` object in :ref:`formatted string
literals <f-strings>` and when using :meth:`str.format`. For a
complete list of formatting directives, see
:ref:`strftime-strptime-behavior`.
2007-08-15 11:28:22 -03:00
.. method:: time.utcoffset()
If :attr:`.tzinfo` is ``None``, returns ``None``, else returns
2007-08-15 11:28:22 -03:00
``self.tzinfo.utcoffset(None)``, and raises an exception if the latter doesn't
return ``None`` or a :class:`timedelta` object representing a whole number of
minutes with magnitude less than one day.
.. method:: time.dst()
If :attr:`.tzinfo` is ``None``, returns ``None``, else returns
2007-08-15 11:28:22 -03:00
``self.tzinfo.dst(None)``, and raises an exception if the latter doesn't return
``None``, or a :class:`timedelta` object representing a whole number of minutes
with magnitude less than one day.
.. method:: time.tzname()
If :attr:`.tzinfo` is ``None``, returns ``None``, else returns
2007-08-15 11:28:22 -03:00
``self.tzinfo.tzname(None)``, or raises an exception if the latter doesn't
return ``None`` or a string object.

.. _datetime-tzinfo:
:class:`tzinfo` Objects
-----------------------
.. class:: tzinfo()
This is an abstract base class, meaning that this class should not be
instantiated directly. You need to derive a concrete subclass, and (at least)
supply implementations of the standard :class:`tzinfo` methods needed by the
:class:`.datetime` methods you use. The :mod:`datetime` module supplies
a simple concrete subclass of :class:`tzinfo`, :class:`timezone`, which can represent
timezones with fixed offset from UTC such as UTC itself or North American EST and
EDT.
2007-08-15 11:28:22 -03:00
An instance of (a concrete subclass of) :class:`tzinfo` can be passed to the
constructors for :class:`.datetime` and :class:`.time` objects. The latter objects
view their attributes as being in local time, and the :class:`tzinfo` object
supports methods revealing offset of local time from UTC, the name of the time
zone, and DST offset, all relative to a date or time object passed to them.
2007-08-15 11:28:22 -03:00
Special requirement for pickling: A :class:`tzinfo` subclass must have an
:meth:`__init__` method that can be called with no arguments, else it can be
pickled but possibly not unpickled again. This is a technical requirement that
may be relaxed in the future.
2007-08-15 11:28:22 -03:00
A concrete subclass of :class:`tzinfo` may need to implement the following
methods. Exactly which methods are needed depends on the uses made of aware
:mod:`datetime` objects. If in doubt, simply implement all of them.
2007-08-15 11:28:22 -03:00
2010-06-15 16:24:52 -03:00
.. method:: tzinfo.utcoffset(dt)
2007-08-15 11:28:22 -03:00
Return offset of local time from UTC, in minutes east of UTC. If local time is
west of UTC, this should be negative. Note that this is intended to be the
total offset from UTC; for example, if a :class:`tzinfo` object represents both
time zone and DST adjustments, :meth:`utcoffset` should return their sum. If
the UTC offset isn't known, return ``None``. Else the value returned must be a
:class:`timedelta` object specifying a whole number of minutes in the range
-1439 to 1439 inclusive (1440 = 24\*60; the magnitude of the offset must be less
than one day). Most implementations of :meth:`utcoffset` will probably look
like one of these two::
return CONSTANT # fixed-offset class
return CONSTANT + self.dst(dt) # daylight-aware class
If :meth:`utcoffset` does not return ``None``, :meth:`dst` should not return
``None`` either.
The default implementation of :meth:`utcoffset` raises
:exc:`NotImplementedError`.
2010-06-15 16:24:52 -03:00
.. method:: tzinfo.dst(dt)
2007-08-15 11:28:22 -03:00
Return the daylight saving time (DST) adjustment, in minutes east of UTC, or
``None`` if DST information isn't known. Return ``timedelta(0)`` if DST is not
in effect. If DST is in effect, return the offset as a :class:`timedelta` object
(see :meth:`utcoffset` for details). Note that DST offset, if applicable, has
already been added to the UTC offset returned by :meth:`utcoffset`, so there's
no need to consult :meth:`dst` unless you're interested in obtaining DST info
separately. For example, :meth:`datetime.timetuple` calls its :attr:`~.datetime.tzinfo`
attribute's :meth:`dst` method to determine how the :attr:`tm_isdst` flag
should be set, and :meth:`tzinfo.fromutc` calls :meth:`dst` to account for
DST changes when crossing time zones.
2007-08-15 11:28:22 -03:00
An instance *tz* of a :class:`tzinfo` subclass that models both standard and
daylight times must be consistent in this sense:
``tz.utcoffset(dt) - tz.dst(dt)``
must return the same result for every :class:`.datetime` *dt* with ``dt.tzinfo ==
2007-08-15 11:28:22 -03:00
tz`` For sane :class:`tzinfo` subclasses, this expression yields the time
zone's "standard offset", which should not depend on the date or the time, but
only on geographic location. The implementation of :meth:`datetime.astimezone`
relies on this, but cannot detect violations; it's the programmer's
responsibility to ensure it. If a :class:`tzinfo` subclass cannot guarantee
this, it may be able to override the default implementation of
:meth:`tzinfo.fromutc` to work correctly with :meth:`astimezone` regardless.
Most implementations of :meth:`dst` will probably look like one of these two::
def dst(self, dt):
2007-08-15 11:28:22 -03:00
# a fixed-offset class: doesn't account for DST
return timedelta(0)
or ::
def dst(self, dt):
2007-08-15 11:28:22 -03:00
# Code to set dston and dstoff to the time zone's DST
# transition times based on the input dt.year, and expressed
# in standard local time. Then
if dston <= dt.replace(tzinfo=None) < dstoff:
return timedelta(hours=1)
else:
return timedelta(0)
The default implementation of :meth:`dst` raises :exc:`NotImplementedError`.
2010-06-15 16:24:52 -03:00
.. method:: tzinfo.tzname(dt)
2007-08-15 11:28:22 -03:00
Return the time zone name corresponding to the :class:`.datetime` object *dt*, as
2007-08-15 11:28:22 -03:00
a string. Nothing about string names is defined by the :mod:`datetime` module,
and there's no requirement that it mean anything in particular. For example,
"GMT", "UTC", "-500", "-5:00", "EDT", "US/Eastern", "America/New York" are all
valid replies. Return ``None`` if a string name isn't known. Note that this is
a method rather than a fixed string primarily because some :class:`tzinfo`
subclasses will wish to return different names depending on the specific value
of *dt* passed, especially if the :class:`tzinfo` class is accounting for
daylight time.
The default implementation of :meth:`tzname` raises :exc:`NotImplementedError`.

These methods are called by a :class:`.datetime` or :class:`.time` object, in
response to their methods of the same names. A :class:`.datetime` object passes
itself as the argument, and a :class:`.time` object passes ``None`` as the
2007-08-15 11:28:22 -03:00
argument. A :class:`tzinfo` subclass's methods should therefore be prepared to
accept a *dt* argument of ``None``, or of class :class:`.datetime`.
2007-08-15 11:28:22 -03:00
When ``None`` is passed, it's up to the class designer to decide the best
response. For example, returning ``None`` is appropriate if the class wishes to
say that time objects don't participate in the :class:`tzinfo` protocols. It
may be more useful for ``utcoffset(None)`` to return the standard UTC offset, as
there is no other convention for discovering the standard offset.
When a :class:`.datetime` object is passed in response to a :class:`.datetime`
2007-08-15 11:28:22 -03:00
method, ``dt.tzinfo`` is the same object as *self*. :class:`tzinfo` methods can
rely on this, unless user code calls :class:`tzinfo` methods directly. The
intent is that the :class:`tzinfo` methods interpret *dt* as being in local
time, and not need worry about objects in other timezones.
There is one more :class:`tzinfo` method that a subclass may wish to override:
2010-06-15 16:24:52 -03:00
.. method:: tzinfo.fromutc(dt)
2007-08-15 11:28:22 -03:00
This is called from the default :class:`datetime.astimezone()`
implementation. When called from that, ``dt.tzinfo`` is *self*, and *dt*'s
date and time data are to be viewed as expressing a UTC time. The purpose
of :meth:`fromutc` is to adjust the date and time data, returning an
equivalent datetime in *self*'s local time.
2007-08-15 11:28:22 -03:00
Most :class:`tzinfo` subclasses should be able to inherit the default
:meth:`fromutc` implementation without problems. It's strong enough to handle
fixed-offset time zones, and time zones accounting for both standard and
daylight time, and the latter even if the DST transition times differ in
different years. An example of a time zone the default :meth:`fromutc`
implementation may not handle correctly in all cases is one where the standard
offset (from UTC) depends on the specific date and time passed, which can happen
for political reasons. The default implementations of :meth:`astimezone` and
:meth:`fromutc` may not produce the result you want if the result is one of the
hours straddling the moment the standard offset changes.
Skipping code for error cases, the default :meth:`fromutc` implementation acts
like::
def fromutc(self, dt):
# raise ValueError error if dt.tzinfo is not self
dtoff = dt.utcoffset()
dtdst = dt.dst()
# raise ValueError if dtoff is None or dtdst is None
delta = dtoff - dtdst # this is self's standard offset
if delta:
dt += delta # convert to standard local time
dtdst = dt.dst()
# raise ValueError if dtdst is None
if dtdst:
return dt + dtdst
else:
return dt
In the following :download:`tzinfo_examples.py
<../includes/tzinfo_examples.py>` file there are some examples of
:class:`tzinfo` classes:
2007-08-15 11:28:22 -03:00
.. literalinclude:: ../includes/tzinfo_examples.py
2007-08-15 11:28:22 -03:00
Note that there are unavoidable subtleties twice per year in a :class:`tzinfo`
subclass accounting for both standard and daylight time, at the DST transition
points. For concreteness, consider US Eastern (UTC -0500), where EDT begins the
minute after 1:59 (EST) on the second Sunday in March, and ends the minute after
1:59 (EDT) on the first Sunday in November::
2007-08-15 11:28:22 -03:00
UTC 3:MM 4:MM 5:MM 6:MM 7:MM 8:MM
EST 22:MM 23:MM 0:MM 1:MM 2:MM 3:MM
EDT 23:MM 0:MM 1:MM 2:MM 3:MM 4:MM
start 22:MM 23:MM 0:MM 1:MM 3:MM 4:MM
end 23:MM 0:MM 1:MM 1:MM 2:MM 3:MM
When DST starts (the "start" line), the local wall clock leaps from 1:59 to
3:00. A wall time of the form 2:MM doesn't really make sense on that day, so
``astimezone(Eastern)`` won't deliver a result with ``hour == 2`` on the day DST
begins. For example, at the Spring forward transition of 2016, we get
>>> from datetime import datetime, timezone
>>> from tzinfo_examples import HOUR, Eastern
>>> u0 = datetime(2016, 3, 13, 5, tzinfo=timezone.utc)
>>> for i in range(4):
... u = u0 + i*HOUR
... t = u.astimezone(Eastern)
... print(u.time(), 'UTC =', t.time(), t.tzname())
...
05:00:00 UTC = 00:00:00 EST
06:00:00 UTC = 01:00:00 EST
07:00:00 UTC = 03:00:00 EDT
08:00:00 UTC = 04:00:00 EDT
2007-08-15 11:28:22 -03:00
When DST ends (the "end" line), there's a potentially worse problem: there's an
hour that can't be spelled unambiguously in local wall time: the last hour of
daylight time. In Eastern, that's times of the form 5:MM UTC on the day
daylight time ends. The local wall clock leaps from 1:59 (daylight time) back
to 1:00 (standard time) again. Local times of the form 1:MM are ambiguous.
:meth:`astimezone` mimics the local clock's behavior by mapping two adjacent UTC
hours into the same local hour then. In the Eastern example, UTC times of the
form 5:MM and 6:MM both map to 1:MM when converted to Eastern, but earlier times
have the :attr:`~datetime.fold` attribute set to 0 and the later times have it set to 1.
For example, at the Fall back transition of 2016, we get
>>> u0 = datetime(2016, 11, 6, 4, tzinfo=timezone.utc)
>>> for i in range(4):
... u = u0 + i*HOUR
... t = u.astimezone(Eastern)
... print(u.time(), 'UTC =', t.time(), t.tzname(), t.fold)
...
04:00:00 UTC = 00:00:00 EDT 0
05:00:00 UTC = 01:00:00 EDT 0
06:00:00 UTC = 01:00:00 EST 1
07:00:00 UTC = 02:00:00 EST 0
Note that the :class:`datetime` instances that differ only by the value of the
:attr:`~datetime.fold` attribute are considered equal in comparisons.
2007-08-15 11:28:22 -03:00
Applications that can't bear wall-time ambiguities should explicitly check the
value of the :attr:`~datetime.fold` attribute or avoid using hybrid
:class:`tzinfo` subclasses; there are no ambiguities when using :class:`timezone`,
or any other fixed-offset :class:`tzinfo` subclass (such as a class representing
only EST (fixed offset -5 hours), or only EDT (fixed offset -4 hours)).
.. seealso::
`datetuil.tz <https://dateutil.readthedocs.io/en/stable/tz.html>`_
The standard library has :class:`timezone` class for handling arbitrary
fixed offsets from UTC and :attr:`timezone.utc` as UTC timezone instance.
*datetuil.tz* library brings the *IANA timezone database* (also known as the
Olson database) to Python and its usage is recommended.
`IANA timezone database <https://www.iana.org/time-zones>`_
The Time Zone Database (often called tz, tzdata or zoneinfo) contains code and
data that represent the history of local time for many representative
locations around the globe. It is updated periodically to reflect changes
made by political bodies to time zone boundaries, UTC offsets, and
daylight-saving rules.
.. _datetime-timezone:
:class:`timezone` Objects
--------------------------
The :class:`timezone` class is a subclass of :class:`tzinfo`, each
instance of which represents a timezone defined by a fixed offset from
UTC. Note that objects of this class cannot be used to represent
timezone information in the locations where different offsets are used
in different days of the year or where historical changes have been
made to civil time.
.. class:: timezone(offset, name=None)
2010-06-15 16:24:52 -03:00
The *offset* argument must be specified as a :class:`timedelta`
object representing the difference between the local time and UTC. It must
2010-06-15 16:24:52 -03:00
be strictly between ``-timedelta(hours=24)`` and
``timedelta(hours=24)`` and represent a whole number of minutes,
otherwise :exc:`ValueError` is raised.
2010-06-15 16:24:52 -03:00
The *name* argument is optional. If specified it must be a string that
will be used as the value returned by the :meth:`datetime.tzname` method.
.. versionadded:: 3.2
2010-06-15 16:24:52 -03:00
.. method:: timezone.utcoffset(dt)
2010-06-15 16:24:52 -03:00
Return the fixed value specified when the :class:`timezone` instance is
constructed. The *dt* argument is ignored. The return value is a
:class:`timedelta` instance equal to the difference between the
local time and UTC.
2010-06-15 16:24:52 -03:00
.. method:: timezone.tzname(dt)
Return the fixed value specified when the :class:`timezone` instance
is constructed. If *name* is not provided in the constructor, the
name returned by ``tzname(dt)`` is generated from the value of the
``offset`` as follows. If *offset* is ``timedelta(0)``, the name
is "UTC", otherwise it is a string 'UTC±HH:MM', where ± is the sign
of ``offset``, HH and MM are two digits of ``offset.hours`` and
2010-06-15 16:24:52 -03:00
``offset.minutes`` respectively.
.. versionchanged:: 3.6
Name generated from ``offset=timedelta(0)`` is now plain 'UTC', not
'UTC+00:00'.
2010-06-15 16:24:52 -03:00
.. method:: timezone.dst(dt)
Always returns ``None``.
2010-06-15 16:24:52 -03:00
.. method:: timezone.fromutc(dt)
2010-06-15 16:24:52 -03:00
Return ``dt + offset``. The *dt* argument must be an aware
:class:`.datetime` instance, with ``tzinfo`` set to ``self``.
Class attributes:
.. attribute:: timezone.utc
2010-06-15 16:24:52 -03:00
The UTC timezone, ``timezone(timedelta(0))``.

:meth:`strftime` and :meth:`strptime` Behavior
----------------------------------------------
2007-08-15 11:28:22 -03:00
:class:`date`, :class:`.datetime`, and :class:`.time` objects all support a
2007-08-15 11:28:22 -03:00
``strftime(format)`` method, to create a string representing the time under the
control of an explicit format string. Broadly speaking, ``d.strftime(fmt)``
acts like the :mod:`time` module's ``time.strftime(fmt, d.timetuple())``
although not all objects support a :meth:`timetuple` method.

For :class:`date` objects, the format codes for hours, minutes, seconds, and
microseconds should not be used, as :class:`date` objects have no such
values. If they're used anyway, ``0`` is substituted for them.

The full set of format codes supported varies across platforms, because Python
calls the platform C library's :func:`strftime` function, and platform
variations are common. To see the full set of format codes supported on your
platform, consult the :manpage:`strftime(3)` documentation.

The following is a list of all the format codes that the C standard (1989
version) requires, and these work on all platforms with a standard C
implementation. Note that the 1999 version of the C standard added additional
format codes.

Several additional directives not required by the C89 standard are included for
convenience. These parameters all correspond to ISO 8601 date values. These
may not be available on all platforms when used with the :meth:`strftime`
method. The ISO 8601 year and ISO 8601 week directives are not interchangeable
with the year and week number directives above. Calling :meth:`strptime` with
incomplete or ambiguous ISO 8601 directives will raise a :exc:`ValueError`.

Notes:
(1)
Because the format depends on the current locale, care should be taken when
making assumptions about the output value. Field orderings will vary (for
example, "month/day/year" versus "day/month/year"), and the output may
contain Unicode characters encoded using the locale's default encoding (for
2013-10-29 04:05:10 -03:00
example, if the current locale is ``ja_JP``, the default encoding could be
any one of ``eucJP``, ``SJIS``, or ``utf-8``; use :meth:`locale.getlocale`
to determine the current locale's encoding).

The :meth:`strptime` method can parse years in the full [1, 9999] range, but
years < 1000 must be zero-filled to 4-digit width.
2011-01-10 19:28:33 -04:00
.. versionchanged:: 3.2
In previous versions, :meth:`strftime` method was restricted to
years >= 1900.
.. versionchanged:: 3.3
In version 3.2, :meth:`strftime` method was restricted to
years >= 1000.
(3)
When used with the :meth:`strptime` method, the ``%p`` directive only affects
the output hour field if the ``%I`` directive is used to parse the hour.
(4)
Unlike the :mod:`time` module, the :mod:`datetime` module does not support
leap seconds.
(5)
When used with the :meth:`strptime` method, the ``%f`` directive
accepts from one to six digits and zero pads on the right. ``%f`` is
an extension to the set of format characters in the C standard (but
implemented separately in datetime objects, and therefore always
available).
2011-01-10 19:28:33 -04:00
(6)
For a naive object, the ``%z`` and ``%Z`` format codes are replaced by empty
strings.
For an aware object:
``%z``
:meth:`utcoffset` is transformed into a 5-character string of the form
+HHMM or -HHMM, where HH is a 2-digit string giving the number of UTC
offset hours, and MM is a 2-digit string giving the number of UTC offset
minutes. For example, if :meth:`utcoffset` returns
``timedelta(hours=-3, minutes=-30)``, ``%z`` is replaced with the string
``'-0330'``.
``%Z``

be a string.

Similar to ``%U`` and ``%W``, ``%V`` is only used in calculations when the
day of the week and the ISO year (``%G``) are specified in a
:meth:`strptime` format string. Also note that ``%G`` and ``%Y`` are not
interchangeable.
