Question

I want to check the date which must be in the format dd-mm-yyyy using a regular expression, and it also must check the leap year dates.

I am using RegularExpressionValidator for checking the date.

Answer 1

Try this regular expression-

^(((((0[1-9])|(1\d)|(2[0-8]))-((0[1-9])|(1[0-2])))|((31-((0[13578])|(1[02])))|((29|30)-((0[1,3-9])|(1[0-2])))))-((20[0-9][0-9]))|(29-02-20(([02468][048])|([13579][26]))))$
