You can't validate dates this way - this would allow e.g. 99/99/0000

Are you trying to do this in client-side JavaScript...?

Hi,

In addition to Mark's reply you have to consider every aspect of the date
validation, lexical and logical validation (number of days in a certain
month, leap years etc.)
