How about an abstract Event class.  The class should have a method that
given a date returns true/false depending if the event occurs on that date.
Now you just subclass as needed to support recurring, one-off or ranges
Event objects.  Would this work?

Could you then use ZCatalog to find all events occuring on a certain date?
