Joda-Time provides a Java library for date and time handling including
the ISO8601 standard. It completely replaces the JDK Date and Calendar
classes, while still providing good integration. It is open-source
software under the ASF2 license.

The major 1.0 release has just been completed after more than a year
of development, testing and beta releases. We consider Joda-Time ready
for production use.

Major features of Joda-Time
---------------------------
- Easy to Use - Calendar makes accessing 'normal' dates difficult, due
to the lack of simple methods. Joda-Time has straightforward field
accessors. And the index of January is 1!

- Extensible - Joda-Time supports multiple calendar systems via a
plugin mechanism, which is much more extensible than the subclasses of
Calendar. Currently supported calendars are ISO8601, GregorianJulian,
Buddhist (Thai) and Coptic.

- Comprehensive - Joda-Time includes classes for datetimes, dates
without times, times without dates, intervals and time periods.

- Advanced formatting - An advanced and extensible formatting
mechanism is included, allowing input and output to string in a
thread-safe manner.

- Well documented. There is documentation in the form of a quick and
full user guide, plus reference pages, FAQs and javadoc.

- Tested. There is good test coverage, see the website, providing an
assurance of quality.

Feedback

As always, let us have any feedback - whether bugs or reviews, good or
bad! Only with the input from the community can the library improve.
