Luxon: The Successor to Moment

Build by one of the core maintainers of Moment.js, **Luxon** was designed to solve all of Moment's historic problems while maintaining a similar, developer-friendly API.

Immutability by Default

In Luxon, all objects are immutable. When you run `dateTime.plus({ days: 7 })`, it returns a *new* instance. This eliminates the "accidental mutation" bugs that plagued Moment users for years.

Native Intl Support

Unlike Moment, which required massive "locale" files to translate month names, Luxon uses the browser's native **Intl (Internationalization) API**. This significantly reduces the bundle size of your application while providing world-class support for hundreds of languages and calendar systems.

First-Class Timezones

Luxon treats timezones as a core concept. It allows you to wrap a UTC timestamp in a specific IANA zone (like `America/New_York`) with a single function call, making it the primary choice for applications that need to display different times to different users.

Conclusion

Luxon is the "grown-up" version of Moment. It is stable, predictable, and perfectly suited for modern, functional JavaScript applications. On the Epoch Clock, we recommend Luxon for any developer looking for a comprehensive, production-ready time library.
