    Joda-Time

    Joda-Time

    Replacement for the Java date and time classes prior to Java SE 8

Note that from Java SE 8 onwards, users are asked to migrate to java.time (JSR-310) - a core part of the JDK which replaces this project. The design allows for multiple calendar systems, while still providing a simple API.
