JGGJCalendar
A fully customizable datepicker for your Swing application!
...JGGJCalendar is easy to set up in your code and provides a powerful interface with getter and setter methods. It's "locale sensitive" but you can change the Locale and the formatting rules before and after the initialization. JGGJCalendar supports the Gregorian calendar, the Imperial Japanese calendar and Thai Buddhist calendar. It was built to be fully customizable: you can easily change every color of the widget to match your application style and you can easily translate the interface (except for the Locale dependent data).
