The dateutil module provides powerful extensions to
the standard datetime module, available in Python.
Installation
dateutil can be installed from PyPI using pip (note that the package name is
different from the importable name)::
pip install python-dateutil
Download
dateutil is available on PyPI
https://pypi.org/project/python-dateutil/
The documentation is hosted at:
https://dateutil.readthedocs.io/en/stable/
Code
The code and issue tracker are hosted on GitHub:
https://github.com/dateutil/dateutil/
Features
- Computing of relative deltas (next month, next year,
next Monday, last week of month, etc); - Computing of relative deltas between two given
date and/or datetime objects; - Computing of dates based on very flexible recurrence rules,
using a superset of theiCalendar <https://www.ietf.org/rfc/rfc2445.txt>_
specification. Parsing of RFC strings is supported as well. - Generic parsing of dates in almost any string format;
- Timezone (tzinfo) implementations for tzfile(5) format
files (/etc/localtime, /usr/share/zoneinfo, etc), TZ
environment string (in all known formats), iCalendar
format files, given ranges (with help from relative deltas),
local machine timezone, fixed offset timezone, UTC timezone,
and Windows registry-based time zones. - Internal up-to-date world timezone information based on
Olson's database. - Computing of Easter Sunday dates for any given year,
using Western, Orthodox or Julian algorithms; - A comprehensive test suite.
Quick example
Here's a snapshot, just to give an idea about the power of the
package. For more examples, look at the documentation.
Suppose you want to know how much time is left, in
years/months/days/etc, before the next easter happening on a
year with a Friday 13th in August, and you want to get today's
date out of the "date" unix system command. Here is the code:
.. code-block:: python3
>>> from dateutil.relativedelta import *
>>> from dateutil.easter import *
>>> from dateutil.rrule import *
>>> from dateutil.parser import *
>>> from datetime import *
>>> now = parse("Sat Oct 11 17:13:46 UTC 2003")
>>> today = now.date()
>>> year = rrule(YEARLY,dtstart=now,bymonth=8,bymonthday=13,byweekday=FR)[0].year
>>> rdelta = relativedelta(easter(year), today)
>>> print("Today is: %s" % today)
Today is: 2003-10-11
>>> print("Year with next Aug 13th on a Friday is: %s" % year)
Year with next Aug 13th on a Friday is: 2004
>>> print("How far is the Easter of that year: %s" % rdelta)
How far is the Easter of that year: relativedelta(months=+6)
>>> print("And the Easter of that year is: %s" % (today+rdelta))
And the Easter of that year is: 2004-04-11
Being exactly 6 months ahead was really a coincidence :)

Starting with version 2.4.1 and running until 2.8.2, all source and binary
distributions will be signed by a PGP key that has, at the very least, been
signed by the key which made the previous release. A table of release signing
keys can be found below:

New releases may have signed tags, but binary and source distributions
uploaded to PyPI will no longer have GPG signatures attached.
