Here's a more concise way of doing it: int year = 2012; // or whatever int daysInYear = DateTime.IsLeapYear(year) ? 366 : 365; Console.WriteLine(daysInYear); // 366 int startIndex = (7 - (int)new DateTime(year, 1, 1).DayOfWeek) % 7; int numSundays = (daysInYear - startIndex >= 365) ? 53 : 52; int diyExceptSunday = daysInYear - numSundays; Console.WriteLine(diyExceptSunday); // 313

hi, try.... private static int GetDaysInAYearWithoutSunday(int year) { int days = 0; for (int i = 1; i { int sundaycount = GetNumberOfSundays(i, year); days = days += sundaycount; } return days; } private static int GetNumberOfSundays(Int32 Month, Int32 Year) { DateTime StartDate = new DateTime(Year, Month, 1); Int32 iDays = DateTime.DaysInMonth(Year, Month); DateTime EndDate = StartDate.AddDays(iDays - 1); Int32 SundayCount = 0; while (StartDate.DayOfWeek != DayOfWeek.Sunday) { StartDate = StartDate.AddDays(1); } SundayCount = 1; StartDate = StartDate.AddDays(7); while (StartDate { SundayCount += 1; StartDate = StartDate.AddDays(7); } return iDays - SundayCount; } static void Main(string[] args) { int vvv = GetDaysInAYearWithoutSunday(2012); } hope this will help you.
