the calendar is awesome ... thank you so much for this!

I'm currently trying to include it as a flat calendar into a small site which has a database driven event calendar. I use ColdFusion for the dynamic part. So far, I have managed to read "special dates" (= days with some kind of event) from the database and mark them in the calendar, disabling all other dates, so that only dates with some event can be clicked.

Next I'd love to add a tooltip to these dates. The idea would be to read short event descriptions for each special date from the database, along with the special dates themselves, and attach them to the tooltip for these dates. Is there already something prepared for this and where? I can't seem to find anything (although the calender "provides help hints (also configurable)") and I don't quite understand how to write a function to add custom made tooltips for days. I'm sure it must be easy.
