## Description

date-fns is a JavaScript date utility library providing a collection of pure functions for manipulating, formatting, and calculating dates and times. It serves as an immutable date manipulation library and a tool for time zone management, ensuring that date transformations are performed without modifying the original date objects.

The library functions as a date formatting tool that converts date objects into human-readable strings using custom patterns and international locales. It includes a specific toolset for adjusting and calculating date representations across different geographical regions and time offsets.

The project covers a broad range of temporal capabilities, including date manipulation, temporal data calculation, and international date formatting tailored to regional standards.
