Tempo is a tiny, tree-shakable JavaScript/TypeScript library for parsing, formatting, manipulating, and internationalizing dates and times. It works with native Date objects and leverages Intl.DateTimeFormat under the hood for timezone offsets and locale-aware formatting.

Use cases

• format dates for different locales in javascript
• parse a date string in any format
• convert dates between timezones
• manipulate and add to dates in typescript
• replace moment.js with a tiny date library
• internationalize date and time formatting in a web app

When to choose

• you want a very small, tree-shakable date utility library
• you prefer working with native Date objects instead of custom date primitives
• you need locale-aware formatting or timezone handling without heavy dependencies

When to avoid

• you need complex calendar features like recurring events or full calendar UI
• you already rely on a mature ecosystem like date-fns or Luxon with plugins
• you need immutable custom date types with rich chaining APIs
