## Description

Luxon is a JavaScript library for parsing, validating, manipulating, and formatting dates and times. It provides a suite of immutable objects for managing points in time, durations, and intervals, ensuring that all transformations return new instances to maintain predictable state.

The library distinguishes itself by leveraging the native Internationalization API and environment-based time zone databases. This architecture allows for localized date formatting and global time zone conversions without requiring external data files or additional dependencies. It also supports non-Gregorian calendar systems to accommodate diverse regional requirements.

The library features a chainable, fluent interface that organizes complex temporal operations into readable sequences. Its core design separates parsing logic from rendering logic, providing a consistent framework for calendar arithmetic, interval calculations, and cross-cultural date representation.
