When I test this, it appears that it validates almost any year as valid. For example, 030/10/05 193/10/05 200040343/10/05 all validate as a match.... Any way to get the year portion to only match 1600 - 9999 years?

Basically the (?:...) construct prevents the regex engine from remembering value matched inside the parenthesis
Normally the value match inside of parenthesis, a group or submatch, is stored for later use, a backreference.

Here is a 1900-1999 version with leap years for that period still intact
^(?:(?:(?:(?:19)(?:0[48]|[2468][048]|[13579][26])))(\/|-|\.)(?:0?2\1(?:29))$)|(?:(?:19)\d{2})(\/|-|\.)(?:(?:(?:0?[13578]|1[02])\2(?:31))|(?:(?:0?[1,3-9]|1[0-2])\2(29|30))|(?:(?:0?[1-9])|(?:1[0-2]))\2(?:0?[1-9]|1\d|2[0-8]))$

Ha Ha! This year there were 29 days in February.
Anyway try http://www.regexlib.com/REDetails.aspx?regexp_id=95
it always allows Feb 29 but you should be able change that to suit your needs.

Thanks for your quick reply. How about I assume there is only 28 days in Feb. Like if this is only for this year.
Thanks.

If you don't validate leap year you can't validate days in Feb.

You could also try updating to the latest version of the
Window scripting enigine http://msdn.microsoft.com/library/default.asp?url=/nhp/default.asp?contentid=28001169
if you don't have the latest version and see if that helps

I looked at that link but I don't see how that would apply since the regex doesn't meet that critera.
This is only one repetition factor in the entire expression \d{2}.
You can try and replace it with \d\d
Maybe IE5's regex engine doesn't support {n} repetitions. Anyone know?

It might be easier to check the year in your code
Starting on such an odd year (1753) makes modifying the year checks tricky because you have to
1) check the year in two places. Leap and non-leap years
2a) starting in the middle of the century and
2b) starting a 1/3 into the decade will require two special checks
for 1753-1799 for both year checks
However instead of changing the original regex I appended a negative look-ahead for the years 1600-1752
(?!(?:16\d\d|(?:17(?:[1-4]\d|5[012]))))
actual
The following regex should work but you should give it some more testing.
^(?!(?:16\d\d|(?:17(?:[1-4]\d|5[012]))))(?:(?:(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))(\/|-|\.)(?:0?2\1(?:29))$)|(?:(?:1[6-9]|[2-9]\d)?\d{2})(\/|-|\.)(?:(?:(?:0?[13578]|1[02])\2(?:31))|(?:(?:0?[1,3-9]|1[0-2])\2(29|30))|(?:(?:0?[1-9])|(?:1[0-2]))\2(?:0?[1-9]|1\d|2[0-8])))$
of course the two digit years would still take 00-99 since no century is ass

That would depend on what you wanted to change the starting and ending years to.
I'm guessing you want a narrower range?
