Hello perl gurus, I am trying to have a regular expression to validate a string to that it is in the format yyyy/mm/dd, and also within the range of 1753/01/01 and 9999/31/31.

I have managed to do this with this simple regex:

((17((5[3-9])|([6-9]\d)))|((18|19)\d\d)|([2-9]\d\d\d))[-/.](0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])

However, obviously this doesn't take care of leap years, and february dates. How can I achieve this? I am completely stuck.

Thanks all
