## What it is
Pendulum is a Python library that provides a cleaner, more intuitive API for working with dates, times, and timezones as a drop-in replacement for the standard datetime class. It offers timezone-aware datetimes by default, easy arithmetic, and human-readable duration formatting.

## Use cases
- work with datetimes and timezones in python
- convert timestamps between timezones
- format durations in human-readable words
- handle daylight saving time transitions correctly
- replace python datetime with a better api
- add or subtract days and weeks from dates

## When to choose
- you need timezone-aware datetimes with correct DST handling
- you want a drop-in replacement for datetime with a friendlier API
- you need human-readable diffs like '2 minutes ago'

## When to avoid
- you only need basic datetime features already covered by the standard library
- your code passes datetimes to libraries that check types with type(), like sqlite3 or PyMySQL

## Facets
- artifact type: library
- maturity: active
- function: date-time, internationalization
- domain: developer-tools, cross-platform
- platform: python, cross-platform
- tags: datetime, timezone, human-readable-durations, drop-in-replacement
