This library allows +accurate and cross platform timezone calculations using Python 2.4 +or higher. It also solves the issue of ambiguous times at the end +of daylight saving time, which you can read more about in the Python +Library Reference (``datetime.tzinfo``). + +Almost all of the Olson timezones are supported. + +.. note:: + + This library differs from the documented Python API for + tzinfo implementations; if you want to create local wallclock + times you need to use the ``localize()`` method documented in this + document. In addition, if you perform date arithmetic on local + times that cross DST boundaries, the result may be in an incorrect + timezone (ie. subtract 1 minute from 2002-10-27 1:00 EST and you get + 2002-10-27 0:59 EST instead of the correct 2002-10-27 1:59 EDT). A + ``normalize()`` method is provided to correct this. Unfortunately these + issues cannot be resolved without modifying the Python datetime + implementation (see PEP-431). + + +Installation +~~~~~~~~~~~~ + +This package can either be installed using ``pip`` or from a tarball using the +standard Python distutils. + +If you are installing using ``pip``, you don't need to download anything as the +latest version will be downloaded for you from PyPI:: + + pip install pytz + +If you are installing from a tarball, run the following command as an +administrative user:: + + python setup.py install + + +Example & Usage +~~~~~~~~~~~~~~~ + +Localized times and date arithmetic +----------------------------------- + +>>> from datetime import datetime, timedelta +>>> from pytz import timezone +>>> import pytz +>>> utc = pytz.utc +>>> utc.zone +'UTC' +>>> eastern = timezone('US/Eastern') +>>> eastern.zone +'US/Eastern' +>>> amsterdam = timezone('Europe/Amsterdam') +>>> fmt = '%Y-%m-%d %H:%M:%S %Z%z' + +This library only supports two ways of building a localized time.

For example, in the US/Eastern timezone +on the last Sunday morning in October, the following sequence +happens: + + - 01:00 EDT occurs + - 1 hour later, instead of 2:00am the clock is turned back 1 hour + and 01:00 happens again (this time 01:00 EST) + +In fact, every instant between 01:00 and 02:00 occurs twice. This means +that if you try and create a time in the 'US/Eastern' timezone +the standard datetime syntax, there is no way to specify if you meant +before of after the end-of-daylight-saving-time transition. Using the +pytz custom syntax, the best you can do is make an educated guess: + +>>> loc_dt = eastern.localize(datetime(2002, 10, 27, 1, 30, 00)) +>>> loc_dt.strftime(fmt) +'2002-10-27 01:30:00 EST-0500' + +As you can see, the system has chosen one for you and there is a 50% +chance of it being out by one hour. For some applications, this does +not matter. However, if you are trying to schedule meetings with people +in different timezones or analyze log files it is not acceptable. + +The best and simplest solution is to stick with using UTC. The pytz +package encourages using UTC for internal timezone representation by +including a special UTC implementation based on the standard Python +reference implementation in the Python documentation. + +The UTC timezone unpickles to be the same instance, and pickles to a +smaller size than other pytz tzinfo instances. The UTC implementation +can be obtained as pytz.utc, pytz.UTC, or pytz.timezone('UTC'). + +>>> import pickle, pytz +>>> dt = datetime(2005, 3, 1, 14, 13, 21, tzinfo=utc) +>>> naive = dt.replace(tzinfo=None) +>>> p = pickle.dumps(dt, 1) +>>> naive_p = pickle.dumps(naive, 1) +>>> len(p) - len(naive_p) +17 +>>> new = pickle.loads(p) +>>> new == dt +True +>>> new is dt +False +>>> new.tzinfo is dt.tzinfo +True +>>> pytz.utc is pytz.UTC is pytz.timezone('UTC') +True + +Note that some other timezones are commonly thought of as the same (GMT, +Greenwich, Universal, etc.). The definition of UTC is distinct from these +other timezones, and they are not equivalent. For this reason, they will +not compare the same in Python. + +>>> utc == pytz.timezone('GMT') +False + +See the section `What is UTC`_, below. + +If you insist on working with local times, this library provides a +facility for constructing them unambiguously: + +>>> loc_dt = datetime(2002, 10, 27, 1, 30, 00) +>>> est_dt = eastern.localize(loc_dt, is_dst=True) +>>> edt_dt = eastern.localize(loc_dt, is_dst=False) +>>> print(est_dt.strftime(fmt) + ' / ' + edt_dt.strftime(fmt)) +2002-10-27 01:30:00 EDT-0400 / 2002-10-27 01:30:00 EST-0500 + +If you pass None as the is_dst flag to localize(), pytz will refuse to +guess and raise exceptions if you try to build ambiguous or non-existent +times. + +For example, 1:30am on 27th Oct 2002 happened twice in the US/Eastern +timezone when the clocks where put back at the end of Daylight Saving +Time: + +>>> dt = datetime(2002, 10, 27, 1, 30, 00) +>>> try: +... eastern.localize(dt, is_dst=None) +... except pytz.exceptions.AmbiguousTimeError: +... print('pytz.exceptions.AmbiguousTimeError: %s' % dt) +pytz.exceptions.AmbiguousTimeError: 2002-10-27 01:30:00 + +Similarly, 2:30am on 7th April 2002 never happened at all in the +US/Eastern timezone, as the clocks where put forward at 2:00am skipping +the entire hour: + +>>> dt = datetime(2002, 4, 7, 2, 30, 00) +>>> try: +... eastern.localize(dt, is_dst=None) +... except pytz.exceptions.NonExistentTimeError: +... print('pytz.exceptions.NonExistentTimeError: %s' % dt) +pytz.exceptions.NonExistentTimeError: 2002-04-07 02:30:00 + +Both of these exceptions share a common base class to make error handling +easier: + +>>> isinstance(pytz.AmbiguousTimeError(), pytz.InvalidTimeError) +True +>>> isinstance(pytz.NonExistentTimeError(), pytz.InvalidTimeError) +True + + +A special case is where countries change their timezone definitions +with no daylight savings time switch.

It is a successor to, but distinct +from, Greenwich Mean Time (GMT) and the various definitions of Universal +Time. UTC is now the worldwide standard for regulating clocks and time +measurement. + +All other timezones are defined relative to UTC, and include offsets like +UTC+0800 - hours to add or subtract from UTC to derive the local time. No +daylight saving time occurs in UTC, making it a useful timezone to perform +date arithmetic without worrying about the confusion and ambiguities caused +by daylight saving time transitions, your country changing its timezone, or +mobile computers that roam through multiple timezones. + +.. _Coordinated Universal Time: https://en.wikipedia.org/wiki/Coordinated_Universal_Time + + +Helpers +~~~~~~~ + +There are two lists of timezones provided. + +``all_timezones`` is the exhaustive list of the timezone names that can +be used. + +>>> from pytz import all_timezones +>>> len(all_timezones) >= 500 +True +>>> 'Etc/Greenwich' in all_timezones +True + +``common_timezones`` is a list of useful, current timezones.

The `Unicode Consortium's Unicode Locales (CLDR) <http://cldr.unicode.org>`_ +project provides translations. Thomas Khyn's +`l18n <https://pypi.org/project/l18n/>`_ package can be used to access +these translations from Python. + + +License +~~~~~~~ + +MIT license. + +This code is also available as part of Zope 3 under the Zope Public +License, Version 2.1 (ZPL). + +I'm happy to relicense this code if necessary for inclusion in other +open source projects. + + +Latest Versions +~~~~~~~~~~~~~~~ + +This package will be updated after releases of the Olson timezone +database. The latest version can be downloaded from the `Python Package +Index <https://pypi.org/project/pytz/>`_. The code that is used +to generate this distribution is hosted on launchpad.net and available +using git:: + + git clone https://git.launchpad.net/pytz + +A mirror on github is also available at https://github.com/stub42/pytz + +Announcements of new releases are made on +`Launchpad <https://launchpad.net/pytz>`_, and the +`Atom feed <http://feeds.launchpad.net/pytz/announcements.atom>`_ +hosted there. + + +Bugs, Feature Requests & Patches +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Bugs can be reported using `Launchpad <https://bugs.launchpad.net/pytz>`__. + + +Issues & Limitations +~~~~~~~~~~~~~~~~~~~~ + +- Offsets from UTC are rounded to the nearest whole minute, so timezones + such as Europe/Amsterdam pre 1937 will be up to 30 seconds out.
