[](https://github.com/formkit/tempo/actions/workflows/tests.yml)   # Tempo — The easiest way to work with dates in JavaScript (and TypeScript) Tempo is a new library in a proud tradition of JavaScript date and time libraries. Inspired by the likes of moment.js, day.js, and date-fns Tempo is built from the ground up to be as small and easy to use as possible. Tempo is best thought of as a collection of utilities for working with `Date` objects — an important distinction from other libraries that provide custom date primitives. Under the hood, Tempo mines JavaScript's `Intl.DateTimeFormat` to extract complex data like timezones offsets and locale aware date formats giving you a simple API to format, parse, and manipulates dates. Tempo is tiny tree-shakable framework, you can only take what you need. You can work with timezones with only a few bytes of library code, or perform full international date formatting for ~2Kb (minified and brotlied). [Size Limit](https://github.com/ai/size-limit) controls the size. ## Development Install from the repository root with `pnpm`: ```bash corepack enable pnpm install ``` Build the library: ```bash pnpm build ``` Build the docs app: ```bash pnpm docs-build ``` --- Created by the FormKit team.
