Hi, This is an excellent pattern to validate the date/ date & time. I am fairly new to Regex. Can you please provide the above pattern limiting the century to 19th and 20th (say year between 1900 and 2099).

Hi Michael
Its great work done by you to validate date using a Regular Expression. I have gone through your expresions, but i need the same DATE validation in MMM-DD-YYYY e.g. Feb-29-2008 this format including leap year validation for February 29 also. 
Please let me know if this format of validation is available in your archive at this regexlib.com.
Please mail me to [email protected]
Yours 
Ravi Kumar GVR

is there a way to shorten this expression to only match 'MM/dd/yyyy'? I noticed it matched 'MM-dd-yyyy', that wouldn't be good for me either. I'm new to regex, I have O'Reilly's regex books on order... this expression is close to what i need, I'm not sure what to edit out of it. Could someone email? [email protected], thanks

Sorry, that should read... you can't properly validate leap years with only two digit years.

No, it isn't because you can't leap years properly using two digit years.  Please see http://regexadvice.com/blogs/mash/archive/2004/04/23/304.aspx if you want more info on this.

I can get matches for two-digit years when I modify this for JavaScript. Is this comment useful?

Wow, you're awesome.. Thanks very much, the script works great, the regex works perfect...
I see I really need to set aside more time for learning more about this.. I had no idea that it was that in-depth and inclusive... 
Thanks again, especially for the quick response.

Sorry there was an unescaped / in the pattern. It should be fixed now.
The part of the pattern (?!/31) should be (?!\/31)

your blog listed this as the one for using with javascript, but I get errors with it on this line : 
var oRegExpNewDate = /(?=\d)^(?:(?!(?:10\D(?:0?[5-9]|1[0-4])\D(?:1582))|(?:0?9\D(?:0?[3-9]|1[0-3])\D(?:1752)))((?:0?[13578]|1[02])|(?:0?[469]|11)(?!/31)(?!-31)(?!\.31)|(?:0?2(?=.?(?:(?:29.(?!000[04]|(?:(?:1[^0-6]|[2468][^048]|[3579][^26])00))(?:(?:(?:\d\d)(?:[02468][048]|[13579][26])(?!\x20BC))|(?:00(?:42|3[0369]|2[147]|1[258]|09)\x20BC))))))|(?:0?2(?=.(?:(?:\d\D)|(?:[01]\d)|(?:2[0-8])))))([-.\/])(0?[1-9]|[12]\d|3[01])\2(?!0000)((?=(?:00(?:4[0-5]|[0-3]?\d)\x20BC)|(?:\d{4}(?!\x20BC)))\d{4}(?:\x20BC)?)(?:$|(?=\x20\d)\x20))?((?:(?:0?[1-9]|1[012])(?::[0-5]\d){0,2}(?:\x20[aApP][mM]))|(?:[01]\d|2[0-3])(?::[0-5]\d){1,2})?$/;
I've tried it with and without the starting and ending /.
I get this error:
Error: Expected ')' in regular expression.
I copied the code from the test page.. Any ideas?
Thanks
