Simple module to parse ISO 8601 dates

Project description

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:

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

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.

Changes

See CHANGELOG.md.
