This datepicker widget uses Prototype and Scriptaculous. It was originally created by Mathieu Jondet (mathieu@eulerian.com) of Eulerian Technologies and includes code by Arturas Slajus for extending the formatting. Mathieu has moved on, but I want to keep developing this. Let me know if you would like to as well. Contact me at tigre@pobox.com

v1.0 now includes customizable and combinable date filters to limit what dates can be selected. There's even an example of using a Google calendar as the data source for a filter.

Key features: * Customizable and combinable date filters * Customizable callbacks when selecting a date, or just closing * Multi-language support: * English * French * Spanish * Italian * German * Portuguese * Dutch * Danish * Hungarian * Lithuanian * Latvian * Polish * Norwegian * Swedish * Finnish * Romanian * Chinese * Japanese * Customizable date format, and language-specific defaults * All Scriptaculous effects available for opening and closing the widget
