Olson Timezone Database for Python

pytzdata is a Python library that provides access to the IANA/Olson timezone database files. It packages a snapshot of this database, allowing applications to retrieve raw timezone definitions. The current version, 2020.1, was released in July 2020. The project does not appear to follow a regular release cadence and is effectively in maintenance mode, largely superseded by the standard library `zoneinfo` module in Python 3.9+ and the `tzdata` package.
