iZeit is an easy to use online PHP calendar. Unlike other online calendars such as Google or 30Boxes, iZeit runs on your own server, so it's totally customizable. The development team is constantly looking for suggestions for future versions of the calendar, so if you think of something not yet implemented, let us know!
