the XML Calendar (formerly known as the 9k XML Calendar, but with enhancements has grown to 15k) is my experiment with XML and the Date object in Flash 5's ActionScipt. The external XML data file for the events can be exchanged for your own set of events. Updated Dec 2001. Read about the changes here.
For your own copy, email me [adam at admataz dot com] and I'll send you a copy of the .fla with instructions to make your own events.xml files
