Dayjs

Day.js is a lightweight utility for parsing, validating, and manipulating date objects. It provides a fluent, chainable interface that allows for complex time calculations and transformations to be performed through a sequence of readable method calls. By utilizing an immutable wrapper pattern, the library ensures data integrity by creating new instances for every operation rather than modifying existing objects.

The project is distinguished by a minimalist core abstraction that maintains a small footprint by offloading non-essential features to an optional, modular plugin system. This architecture allows developers to extend functionality or add specialized formatting capabilities by registering independent modules only when needed. Furthermore, the library includes an internationalization engine that supports dynamic, lazy loading of locale data to keep bundle sizes minimal while respecting regional date and time conventions.
