To be honest, this is one of the best calendar I have ever seen. I was really excited when I was playing with Calendar. It is powerful and yet really easy to implement. You can also have different CSS Styling for the calendar.
Calendar has been successfully tested in Safari, Firefox, Opera and Internet Explorer. The class requires Mootools 1.1 with Fx.Style, Element and Window. In order to enable dragging, the class also requires the Drag component.
Requirements: Safari, Firefox, Opera and Internet Explorer with Mootools Framework
