AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Arrow provides a human-friendly Python library for creating, manipulating, formatting, and converting dates, times, and timestamps with timezone awareness and ISO 8601 support built in.

Low friction: pure-Python wheel with only three runtime dependencies (python-dateutil, backports.zoneinfo, tzdata). Actively maintained with recent releases and 9049 GitHub stars.

Permissive Apache license allows commercial and private use with minimal restrictions.

Usage

pip install arrow

import arrow
utc = arrow.utcnow()
local = utc.to('US/Pacific')
print(local.humanize())

Verdict: Arrow is a stable, well-maintained datetime library with low install friction and no known vulnerabilities. Its permissive license and active development (299 days since last release, active status) make it a reliable choice for date/time handling in Python 3.8+.
