Well, the .NET Framework doesn't contain a DateTimePicker control for ASP.NET so I assume you must be using a custom control.

If so replace the Value property in the following expression with whatever property in your control gives the currently selected date as a DateTime:

bool isValid = (DateTimePicker1.Value.DayOfWeek == DayOfWeek.Monday)
&& (DateTimePicker2.Value.DayOfWeek == DayOfWeek.Saturday)
&& ((DateTimePicker2.Value.Date - DateTimePicker1.Value.Date).Days == 12);
