public class Example
   public static void Main()
      Calendar cal = new UmAlQuraCalendar();
      int currentYear = cal.GetYear(DateTime.Now);

      for (int year = currentYear; year <= currentYear + 9; year++)
         Console.WriteLine("{0:d4}: {1} days {2}", year, 
                           cal.GetDaysInYear(year, UmAlQuraCalendar.UmAlQuraEra), 
                           cal.IsLeapYear(year, UmAlQuraCalendar.UmAlQuraEra) ?
                              "(Leap Year)" : "");        
// The example displays the following output:
//       1431: 354 days
//       1432: 354 days
//       1433: 355 days (Leap Year)
//       1434: 354 days
//       1435: 355 days (Leap Year)
//       1436: 354 days
//       1437: 354 days
//       1438: 354 days
