Datejs is an open-source JavaScript library for parsing, formatting, and processing dates and times, with support for 150+ cultures. It provides a fluent, chainable API for date manipulation such as relative dates, comparisons, and arithmetic.

Use cases

• parse human-readable date strings in javascript
• format dates for different locales and cultures
• compute relative dates like next friday or three months ago
• add and subtract days, months, or years from dates
• check whether a date is a weekday or specific month
• convert between php/unix date formats and javascript

When to choose

• you need natural-language date parsing with strong culture/locale support in a legacy javascript project
• you want a lightweight, dependency-free date utility with a fluent chainable api

When to avoid

• you are starting a new project and need actively maintained software
• you need timezone-aware date handling (use a modern library like date-fns, Luxon, or Day.js)
• you need modern ES module or TypeScript support
