Comment:
The way the RegEx is currently written, Feb. the 19 of any year is invalid.
this line:
([0][1-9]|[12][0-8])
Should read:
([0][1-9]|[1][\d]|[2][0-8])
Title: Leap years messed up in modified code

Comment:
Now the leap year dates don't seem to work with the modified code given July 16, 2004. Example:
29/02/2004, 29/02/1996, 29-02-1992
Title: Even Better Date Validation

Comment:
Improved to include validation of leap years 1000 through 9999 (includes the Gregorian divisible by 100 and divisible by 400 check: thanks for the heads up Michael).

If you are basing this on the Gregorian Calendar you should know that not all centuries are leap years. 2100, 2200 for example are not leap years. See http://scienceworld.wolfram.com/astronomy/GregorianCalendar.html
They are several date regexs on this library that also include the century check that you can look at
