Update 21 November 2005: Added the "addMonths" method and removed the GregorianCalendar field to reduce memory footprint.
There jar containing the CalendarDate .java and .class files is here.
As the CalendarDate distribution is just two classes, it may be easier to just download them
Javadoc is here.
Unit tests for CalendarDate are available from the project's CVS repository. Code coverage results for these tests are here.
