Date-fns Date Utility Patterns

This skill provides specialized guidance for using date-fns, the functional and modular date utility library, within TypeScript projects. It enforces best practices such as immutable date operations, safe ISO parsing, and tree-shakeable imports to minimize bundle sizes. Whether you are handling complex timezones with @date-fns/tz, generating localized date strings, or performing precise date arithmetic, this skill ensures your implementation follows modern standards and avoids common pitfalls like browser-inconsistent native Date parsing and side-effect-prone mutations.
