      myCals[4] = new KoreanCalendar();
      myCals[5] = new TaiwanCalendar();
      myCals[6] = new ThaiBuddhistCalendar();

      // For each calendar, displays the current year, the number of months in that year,
      // and the number of days in each month of that year.
      int i, j, iYear, iMonth, iDay;
      DateTime myDT = DateTime.Today;

      for (i = 0; i < myCals.Length; i++)
