Joda-Time is a quality date and time library for Java, serving as the de facto standard replacement for the poor JDK date/time classes prior to Java SE 8. It provides immutable, thread-safe classes like DateTime, LocalDate, and Period, supports multiple calendar systems, and is now in maintenance mode with users encouraged to migrate to java.time (JSR-310).
Use cases
- handle dates and times in Java before JDK 8
- work with multiple calendar systems like Buddhist or Islamic
- calculate differences between two dates
- format and parse dates with time zones
- represent dates without time or times without dates
- handle daylight savings transitions correctly
- support date/time on older Android API levels
When to choose
- maintaining legacy Java codebases predating Java SE 8
- needing calendar systems beyond Gregorian (Buddhist, Coptic, Ethiopic, Islamic)
- supporting Android API levels below 26 where java.time is unavailable
- requiring a proven, stable, thread-safe date/time API
When to avoid
- starting a new project on Java SE 8 or later (use java.time instead)
- targeting Android API 26+ (use built-in java.time)
- needing active development or new features (project is maintenance-only)
- willing to use ThreeTenABP backport on older Android
