## What it is
Luxon is a JavaScript library for working with dates and times, providing DateTime, Duration, and Interval types with an immutable, chainable API. It leverages native Intl and time zone support, requiring no locale or tz data files.

## Use cases
- format dates in JavaScript
- convert timestamps between timezones
- parse date strings into datetime objects
- calculate durations between dates
- handle locale-aware date formatting
- work with ISO 8601 dates

## When to choose
- you need robust timezone handling in JS without extra tz data files
- you want an immutable, modern alternative to Moment.js
- you need locale-aware formatting via native Intl

## When to avoid
- you need date scheduling/calendar UI components
- your environment lacks Intl support
- you only need simple date math and want a tiny dependency

## Facets
- artifact type: library
- maturity: stable
- function: date-time, internationalization
- domain: developer-tools, web-development
- platform: browser, cross-platform
- tags: datetime, timezones, intl, immutable, javascript, localization, nodejs
