Super AJAX Calendar
Here's a new version of my original AJAX Calendar. It includes lots of new features and a visual refresh. This version features linked events, an admin tool to easily manipulate those events, and a jump to box for jumping straight to the month / year you're looking for. This calendar has everything you need and it's styled with an external CSS style sheet, so you can integrate it into your site with ease! Works perfectly with IE6 and Firefox!
