public class Example
{
   public static void Main()
   {
      DateTime date1 = new DateTime(2011, 4, 3, new GregorianCalendar());
      Calendar cal = new UmAlQuraCalendar();

      Console.WriteLine("{0:MMMM d, yyyy} in the Gregorian calendar is equivalent to:", date1);
      DisplayCalendarInfo(cal, date1);

      // Add 2 years and 10 months by calling UmAlQuraCalendar methods.
      date1 = cal.AddYears(date1, 2);
      date1 = cal.AddMonths(date1, 10);

      Console.WriteLine("After adding 2 years and 10 months in the {0} calendar,",
                        GetCalendarName(cal));
      Console.WriteLine("{0:MMMM d, yyyy} in the Gregorian calendar is equivalent to:", date1);
      DisplayCalendarInfo(cal, date1);
   }

   private static void DisplayCalendarInfo(Calendar cal, DateTime date1)
   {
      Console.WriteLine("   Calendar:   {0}", GetCalendarName(cal));
      Console.WriteLine("   Era:        {0}", cal.GetEra(date1));
      Console.WriteLine("   Year:       {0}", cal.GetYear(date1));

      Console.WriteLine("   DayOfMonth: {0}", cal.GetDayOfMonth(date1));
      Console.WriteLine("   DayOfWeek:  {0}\n", cal.GetDayOfWeek(date1));
   }

   private static string GetCalendarName(Calendar cal)
   {
      return cal.ToString().Replace("System.Globalization.", "").
             Replace("Calendar", "");
   }
