Here is some basic code to work out the number of working days (Monday to Friday) in any given month and year: int[] daysInMonth = {31 28 31 30 31 30 31 31 30 31 30 31}; int month = 6; // June int year = 2012; if (DateTime.IsLeapYear(year)) daysInMonth[1] = 29; DateTime dt = new DateTime(year month 1); int workingDays = 0; for(int i = 1; i { if(dt.DayOfWeek != DayOfWeek.Sunday && dt.DayOfWeek != DayOfWeek.Saturday) workingDays++; dt = dt.AddDays(1); } label1.Text = workingDays.ToString(); // 21 If you want to regard Saturday as a working day then just change this line: if(dt.DayOfWeek != DayOfWeek.Sunday && dt.DayOfWeek != DayOfWeek.Saturday) workingDays++; to this: if(dt.DayOfWeek != DayOfWeek.Sunday) workingDays++;
