Yeah, well let's not go there because some folks even call it recurrence 
when it relies on a fixed day of the week but a count of week into the 
month (like "last Tuesday of every month"). Such moronic scheduling 
should be criminal ;-)

I agree that recurrence should be handled in the presentation layer, 
provided the data is in. but what data? Depends on type of recurrence, 
which is where the business layer interferes with the data layer anyway. 
those damn humans think "every other wednesday" is recurrence.... duh. 
It's really "every other day that has already been assigned the label 
"Wednesday" and that works just fine using the flag approach, right?

I'd appreciate an example of that 'simple math' cliff? Might make it 
clearer what you mean.
