I am not expert in writing regular expressions so need your help. I want to validate date in \"dd-MMM-yyyy\" format i.e. 07-Jun-2012. I am using RegularExpressionValidator i
Yet another idea would be to try this (similar to user1441894's idea):
var x = DateTime.Parse("30-Feb").GetDateTimeFormats();
I learned to use this yesterday (for a different purpose). So try-catch this statement to deal with validity/invalidity of the date :)
