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)" : "");
   }
