The g flag creates it's own index apparently (see: stackoverflow.com/questions/209732/…).

If you use the g flag you will get inconsistent results.

I think it might help if you set an accurate expectation, as this regex does NOT, in fact, correctly validate leap years; e.g., there is no Feb.

It seems that the checking validation of email addresses is actually two separate problems: 1- Validation of email format: Making sure if the email complies with the format and pattern of emails in RFC 5322 and if the TLD actually exists. For example, although the address Thank you for your interest in this question.

To match a date in the format 'yyyy-MM-dd hh:mm' (Or indeed in whatever order you please) 1/1/11 or 1.1.11 or 1-1-11 : true 01/01/11 or or 01-01-11 : true 01/01/2011 or or : true 01/1/2011 or 01.1.2011 or 01-1-2011 : true 1/11/2011 or 1.11.2011 or 1-11-2011 : true 1/11/11 or 1.11.11 or 1-11-11 : true 11/1/11 or 11.1.11 or 11-1-11 : true^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((19|[2-9]\d)\d))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((19|[2-9]\d)\d))|((0[1-9]|1\d|2[0-8])\/02\/((19|[2-9]\d)\d))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$ ((((0[13578]|1[02])(\/|-|.)(0[1-9]|1[0-9]|2[0-9]|3[01]))|((0[469]|11)(\/|-|.)(0[1-9]|1[0-9]|2[0-9]|3[0]))|((02)((\/|-|.)(0[1-9]|1[0-9]|2[0-8]))))(\/|-|.)(19([6-9][0-9])|20(0[0-9]|1[0-4])))|((02)(\/|-|.)(29)(\/|-|.)(19(6[048]|7[26]|8[048]|9[26])|20(0[048]|1[26]))) I suspect that the following is as accurate as can be expected without knowing when the user's locale switched over from the Julian to the Gregorian calendars.

Unfortunately, all it does is match valid numbers in a date time input, and 31st Feb will be marked as valid, but as so many have said, regex really isn't the best tool to do this test.

Here's an example of the above in action: Almost all answers to this questions suggest using Regex to validate emails addresses.

I think Regex is only good for a rudimentary validation.

I'm tired of being told my e-mail address of "foo [email protected]" is invalid.

The best option is to ask the user to type their e-mail in twice and if you MUST use a regex checker, then tell the user that their e-mail address does not appear to be valid and ask if they are sure they typed it right.
