FlatCalendarXP is arguably the most powerful and configurable JavaScript calendar available. There are very few, if any, things that other JavaScript calendars can do that FlatCalendarXP can not. You'll be amazed to see how simple and fast it is to get it generated by a calendar tag - YES! Only one tag* on your web page, no chaos, no mess-up. It features database-driven events/agendas, real cross-browser capability, extremely customizable UI, super easy-to-use design and a compact and fast JavaScript engine. It works perfectly with ASP.NET, ASP, JSP, PHP, ColdFusion and other web frameworks.
