Ron Note that both solutions so far are only partial solutions for most real world scenarios. For example: 0001-12-25 will pass both, and would appear to be Christmas #1 to the average human eye, or a least readily identifiable in context as such. Unfortunately, we've made rather of mess of dates and calendars over the centuries, and 0001-12-25 is unlikely to be "correct" in any real sense of the word, for most applications. So you probably should include several more stringent checks suitable to your web application. Some examples: Birth dates for living humans would be current date - 120 years range. Credit card expirations should be current date + 10 years (I think...) -- Actually, older dates are 'valid' but the credit card won't go through anyway, so that might need 2 separate checks. My point being that there really cannot be a single "valid" date check because there's no way to be certain of the unique needs of your web application. The vagaries of date/time input are legion. And don't even get me started on the goofball 15-minute offset time-zone thing... :-) -- Some people have a "gift" link here. Know what I want?
