Simple module to parse ISO 8601 dates
`pip install iso8601`
Documentation: https://pyiso8601.readthedocs.org/
PyPI: https://pypi.org/project/iso8601/
Source: https://github.com/micktwomey/pyiso8601
This module parses the most common forms of ISO 8601 date strings (e.g. 2007-01-14T20:34:22+00:00) into datetime objects.
>>> import iso8601
>>> iso8601.parse_date("2007-01-25T12:00:00Z")
datetime.datetime(2007, 1, 25, 12, 0, tzinfo=<iso8601.Utc>)
>>>
See the LICENSE file for the license this package is released under.
If you want more full featured parsing look at:

- https://pendulum.eustace.io - pendulum
- https://labix.org/python-dateutil - python-dateutil
- https://docs.python.org/3/library/datetime.html#datetime.datetime.fromisoformat - Yes, Python 3 has built in parsing too!
Parsed Formats
==============
You can parse full date + times, or just the date. In both cases a datetime instance is returned but with missing times defaulting to 0, and missing days / months defaulting to 1.
Dates
-----
- YYYY-MM-DD
- YYYYMMDD
- YYYY-MM (defaults to 1 for the day)
- YYYY (defaults to 1 for month and day)
Times
-----
- hh:mm:ss.nn
- hhmmss.nn
- hh:mm (defaults to 0 for seconds)
- hhmm (defaults to 0 for seconds)
- hh (defaults to 0 for minutes and seconds)
Time Zones
----------
- Nothing, will use the default timezone given (which in turn defaults to UTC).
- Z (UTC)
- +/-hh:mm
- +/-hhmm
- +/-hh
Where it Differs From ISO 8601
==============================
Known differences from the ISO 8601 spec:
- You can use a " " (space) instead of T for separating date from time.
- Days and months without a leading 0 (2 vs 02) will be parsed.
- If time zone information is omitted the default time zone given is used (which in turn defaults to UTC). Use a default of None to yield naive datetime instances.
References

- https://www.cl.cam.ac.uk/~mgk25/iso-time.html - simple overview
- https://web.archive.org/web/20090309040208/http://hydracen.com/dx/iso8601.htm - more detailed enumeration of valid formats.
Testing
=======
1. `poetry install`
2. `poetry run nox`
Note that you need all the pythons installed to perform a tox run (see below). pyenv helps hugely, use pyenv install for the versions you need then use 'pyenv local version ...' to link them in (the tox-pyenv plugin will pick them up).
Alternatively, to test only with your current python:
1. `poetry install`
2. `pytest`
Releasing
=========
1. `just prepare-release`
2. `just do-release`
Supported Python Versions
=========================
Tested against:
- Python 3.7
- Python 3.8
- Python 3.9
- Python 3.10
- Python 3.11
- Python 3.12
- PyPy 3
Python 3 versions < 3.7 are untested but should work.
