Active Calendar is an ASP.NET server control that allows users to select a date and/or time quickly using a professional looking date picker with a client-side managed event system. No postback to the server required, no external script file required.

Active Calendar includes the Active DateTime technology. You can disable the visible calendar format and simply use the Active DateTime component of ActiveCalendar to provide a date/time selector group with client-side validation.
