      ' Gets the calendars supported by the ar-SA culture.
      Dim myOptCals As Calendar() = New CultureInfo("ar-SA").OptionalCalendars

      ' Checks which ones are GregorianCalendar then determines the GregorianCalendar version.
      outputBlock.Text &= "The ar-SA culture supports the following calendars:" & vbCrLf
      Dim cal As Calendar
      For Each cal In myOptCals
         If cal.GetType() Is GetType(GregorianCalendar) Then
            Dim myGreCal As GregorianCalendar = CType(cal, GregorianCalendar)
            Dim calType As GregorianCalendarTypes = myGreCal.CalendarType
            outputBlock.Text += String.Format("   {0} ({1})", cal, calType) & vbCrLf
         Else
            outputBlock.Text += String.Format("   {0}", cal) & vbCrLf
