Just purchased WebCalendar and just having a play with it before Sunday lunch... roast beef takes priority, so must be quick!
I'm currently re-doing our college site, there's a draft at:
Sorry menus don't point anywhere. WebCal was very easy to integrate and a one-time fix will sort the IE problem but haven't bothered with that yet.
One annoying thing is that it seems to truncate the last word of the drop down message when you hover over date, i.e "test" becomes "tes ...", not "test ...". I see Janys has added in blank spaces to get round the issue.
When I played with re-organising date and mixing holidays, etc, I couldn't get it to display both for a given date but thet may be me and I'll have another look and post something if I can duplicate the error.
Janys has put about 3 dots after the word to avoid truncation.......
p.s. Rather than get upset later, I will tell you now, don't bother to try to get several things appearing on your slide-down. If you want several events to show, uncheck the slide-down, and just use the click on date to give a list of more than one event on any day.
p.p.s. Your site has a nice clean start.... look forward to seeing it when you have found time to add more!
