Depending on what you mean with this, I believe Visual Basic (gasp !
shock ! horror !) has a DateSerial function that can overflow in any
direction.  If you want to know the last day of february this year, you
can write DateSerial(2007, 3, 0), for instance.

It's extremely useful.  (And you have the same with TimeSerial, even if
it's a bit less useful.)
