Question

I am trying to write an regular expression in c#
that will check a date (DD/MM/YYYY).

Any date (01/01/0000) or (12/12/9999) will be fine too.
The day time must be from 01-12,
the month time must be from 01-12,
the year time must be from 0000-9999
and between them must be “/”.

Answer 1

^([012]\d|30|31)/(0\d|10|11|12)/\d{4}$

should do it!
