Regex, definitely , is not the right tool to solve this problem.

If you want to compare two dates, then use the struct DateTime .

I'll assume that the input is two strings, s1 and s2 , in a valid format.

var d1 = DateTime.Parse(s1)
var d2 = DateTime.Parse(s2)

d1 < d2

If you are not sure that the string format is valid then you should use DateTime.TryParse
