isoduration

isoduration is a Python library for working with ISO 8601 durations (e.g., 'P3Y6M4DT12H30M5S'). It provides functionality for parsing duration strings, formatting durations, and performing arithmetic operations with Python's `datetime` objects. The library is currently at version 20.11.0, released in 2020, and appears to be in maintenance mode with no recent major releases, though minor updates or repackaging may occur.
