Jquery and Regex numeric check

Question

Hi all having a little problem with regex and Jquery in checking that a date will work correctly.

Currently it doesn't accept the number 01 but does 02+ but works as expected with ranges above 31.

this is the js fiddle page. http://jsfiddle.net/b3aHt/

Thanks

01 fails because of dob < 2.

I don't think regular expressions make for a very neat solution here. I would rather test

if(dob.length != 2 || isNaN(dob) || dob < 0 || dob > 31) {
   // not between 01 and 31
}

oh that was just to check that dobs length was greater than to should that be dob.length < 2?
