Ken, Yeves, et al:

I'm not a regEx user, but doesn't the above accept as valid dates input like:

* 30/02/2002   (Feb 30)
* 31/04/2002   (April 31)
* 29/02/2002   (Feb 29 on non leap years)

etc.?

The Serendipity Library validDate function will correctly validate 
any date as correct or incorrect based on the system date format:
