Python API for dealing with timezones
pytz brings the Olson tz database into Python. 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 savings, which you can read more about in the Python Library Reference (datetime.tzinfo). Projects using Python 3.9 or later should be using the support now included as part of the standard library, and third party packages work with it such as https://pypi.org/project/tzdata/. pytz offers no advantages beyond backwards compatibility with code written for earlier versions of Python.
