I need something much simpler for use in Access. I don't need it to validate as the user will be keying in the DateTime from an email. I will be using this to Index emails into our document management system and can only have 255 total characters. The user will also be keying in the document name with the date and time. For example the document might be named something like this: 165502_227_2018_EMAILCORR mm-dd-YYYY 12:18 PM

There are forced CRLF on this page. The regex should be one long string, no line breaks.
http://regexlib.com/REDetails.aspx?regexp_id=113 is a mm/dd/yyyy date regex. It accept two digit years but removing the question marks before both \d{2} you can make it accept only 4 year dates

I tried using the date expression(with out time check) and it's not working. I think there's a missing parenthesis somewhere and I can't find it. Also, I made a typo in my previous post, I meant to say mm/dd/yyyy; could you flip it around?

Here is the time portion of this regex http://regexlib.com/REDetails.aspx?regexp_id=370
I've posted a dd/mm/yyyy regex here
http://regexlib.com/REDetails.aspx?regexp_id=505
However this regex is geared toward .Net so it may not work with another language. Here is the regex with the time check removed
(?n:^(?=\d)((?<day>31(?!(.0?[2469]|11))|30(?!.0?2)|29(?(.0?2)(?=.{3,4}(1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|(16|[2468][048]|[3579][26])00))|0?[1-9]|1\d|2[0-8])(?<sep>[/.-])(?<month>0?[1-9]|1[012])\2(?<year>(1[6-9]|[2-9]\d)\d{2}))$)

Sorry Jensen but I'm not really an ASP.Net programmer.
I only learned how to implement the asp:RegularExpressionValidator yesterday. I don't know what all the attributes do, so i don't really know what 'static' does in regard to the validator. I just modified some sample code I found.
But assuming you can modify the regex the control uses on the fly then I think you had the right approach to to handling dd/mm/yy. Just use this regex for d/m/y
^(?=\d)(?:(?:31(?!.(?:0?[469]|11))|(?:30|29)(?!.0?2)|29(?=.0?2.(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))|(?:2[0-8]|1\d|0?[1-9]))([-./])(?:1[012]|0?[1-9])\1(?:1[6-9]|[2-9]\d)?\d\d)?(\x20?((0?[1-9]|1[012])(:[0-5]\d){0,2}(\x20[AP]M))|([01]\d|2[0-3])(:[0-5]\d){1,2})?$

Well that is what i did . Does display need to be "static" . I use dynamic.
I also wnat my validator to work as well for german, danish or norwegian datetime.
The problem is that the use dd-mm-yyyy or dd.mm.yyyy.
My first approch was to detect the user language preference and then set the ValidateExpression property of my regular expresssion validator property to the appropriate expression. And i want all tis to happen on the client side.
So far , the "en" (english) one is the only one that works with javascript.
I'am rigth and how could i solve this.

I have just added the string (?:\s+)? before and after the original expression to trim spaces before and after.
It works great.

Feb 29th is only valid in leap years. If you test this RE with 02/29/2100 it will fail, as it should.

This regex validates 01/01/2100...which it should not.
Leap years only occur when the year is divisible by four, or when it is divisible by both 100 and 400.
