Great Calendar! and very flexible

I’ve tried some other calendars but none of the previous I’ve tried fit my needs, I needed one where I can have repetitive events, but with one (or more) occurrence of the event could be with no events due holidays or other events, so I tried to use ‘My Calendar’ I couldn’t make what I wanted, other one I love the view was the ‘Ajax Event Calendar’ where I had problems deleting one occurrence of the event (due new year’s eve) and well, I can continue the list, so I tried this one and it does pretty much what I want with the free version.
Thanks!
