arrow

Arrow provides a drop-in replacement for the standard datetime module with a cleaner API. It supports Python 3.8 and later, defaults to UTC and timezone-aware objects, and can parse many common string formats including ISO 8601. The library offers simple creation methods, a shift method for relative offsets, formatting and parsing with custom patterns, timezone conversion using dateutil, pytz, or ZoneInfo, generation of time spans and ranges, and human-readable relative time strings in multiple locales. Installation is via pip install arrow. The project includes full type hints and extensive documentation at arrow.readthedocs.io.
