Question

I need a regular expression to validate credit card expiry date. Note that the format of the “date” is MM/YY where YY is the year without century and MM is the month (from 01 to 12). I do not need the YY to be in some limited range but only the MM.
Thank you in advance.

Answer 1

This regexp does the job:

(0[1-9]|1[0-2])\/[0-9]{2}

Note that it has a capturing group, depending on your regexp engine you can make it non-capturing like this:

(?:0[1-9]|1[0-2])\/[0-9]{2}
