And which knuckles do you use to remember which years are leap years?  ;)

He does.  In his words: "how can I check whether or not such strings
represent a valid date?"
    
His problem is verifying that the entire date is correct.  By the time you
factor in the varying days of the months and leap years, I can understand
wanting to use a prewritten and tested module rather than an ad-hoc solution
for a problem that many people must have encountered before.
