I have worked extensively with this tag.. Production site I designed is online and has this calendar of events http://www.aley.net/Ar/events/

... and a fine job you have done as well.

This is the source.. It has some arabic text (sorry) but it will help you get the idea behind what I have setup..

Thank You!!! This is the first time that the tag has made sense to me. I'm now in the process of making dirivitaive works of ZCatalog and KMNetNews so that I can create a public updatable calendar.
