Comment:
This is almost an identical copy of my regex http://regexlib.com/REDetails.aspx?regexp_id=369 the only difference is this one only allows one type of date field separator (/) where the original gave you three choices. If you are going to modify someone else's work you should give them credit in the "source" field.
