| Description |
After looking for a date regular expression, I could not find one that meet my need, so I develop one that handles 1 or 2 digets in the month and day and also handle feb up to 29. This will allow both / and - for separators, which is what I needed. I hope this helps others too. Thanks,

allows '99999'. In fact allows just about anything.

I don't know why the search didn't find them before but if you browse the date & times patterns there are regexs here that match. The following also correctly handle leap years.
mm/dd/yy - http://www.regexlib.com/REDetails.aspx?regexp_id=113 and http://www.regexlib.com/RETester.aspx?regexp_id=369
dd/mm/yy - http://www.regexlib.com/REDetails.aspx?regexp_id=151
