Is there a version that requires 4 digit years?  This one seems to accept 2 digit years.

You need an @ before the regex's to avoid Visual Studio giving you an error.
so RegEx.IsMatch(input, @"...");

Hello.  Great expression!  However, I'm looking for one in a different format?  Do you have one, or does any other reader know of one that handles the following formats?
MMDDYY, MMDDYYYY, MM/DD/YY, MM/DD/YYYY
TIA,

here it comes.
As I discovered into your email that you do not need DDMMYYYY validation, I removed it... se here :

After must testing I found this regexp to be the only one to work in all the cases I required, except 1. I need to extend it so that it also accepts 1 digits years (which I will convert with javascript from 0 to 2000, 1 to 2001, etc). I've no experience with regular expression and am finding this probably easy task impossible to complete. 
Thanks in advance for any help.

Here's one in that format.
http://www.regexlib.com/REDetails.aspx?regexp_id=405
although it only uses spaces for separators so would still need slight modification

I'll do one for you if I have time. It's easy...
I will be longer because not numeric, but whatever...
Best regards.

I think this is one of the best regular expressions i have ever seen.
Q: What can be done for this to take dates like: "01-Jan-2003" or: "12-Dec-2004" ... ??
or: 14 Feb 2004 
?
format for .NET is: "dd-MMM-yyyy" 
How can this be done?

On earth, there's sometimes something strange. A metric system exists, as well as a "logical" way to go from the smallest part to he biggest : days, then months, then years.
DD/MM/YY
With a touch of humour.

Doesn't seem to work with 13 or higher in the middle group of digits.  For example, 02/12/03 works but 02/13/03 does not.

Hi Thiago,
try to replace
     [\.\-\/]
with
     [:punct:]
you can find docs about regexp in jakarta here :
http://jakarta.apache.org/regexp/apidocs/org/apache/regexp/RE.html
or java help here:
http://devedge.netscape.com/library/manuals/2000/javascript/1.3/reference/regexp.html
Please, note that this regexp should be java compliant.
Note also the "red" issues of jakarta.
Hope this helps.
Dany

Hi Dany
Thank you for this extremely useful regex. I'm a CTO in a software company, where the pressure hits the roof every day and have no time to sit down and create an expression like this. I'm going to use it in a high profile app for a Scandinavian company. You have already been credited.
Thanks again.

Your welcome guys !
The secret is to separate your expression into very simple working (and 100% tested) regexp, and then respect the logical way to construct a bigger one, and so on...
If you wan, I've got a file with separated expressions (basic month validator, for example, then day validator, then leap year, then non leap year, etc...)
send me a mail.

Too many posted regex's do not work.
AFter testing 12-15 posted regexes, this is the first that I have found that has passed ALL of my tests.
It may still fail some, but works better than any I have found so far.
Well done Dany!
