{
    public static void Main()
    {
      PersianCalendar jc = new PersianCalendar();
      DateTime thisDate = DateTime.Now;

      foreach (int era in jc.Eras)

                        jc.IsLeapYear(1370, PersianCalendar.PersianEra));
        //--------------------------------------------------------------------------------

        // Get the 4-digit year for a year whose last two digits are 99. The 4-digit year
        // depends on the current value of the TwoDigitYearMax property.

// The example displays the following output:

//         If TwoDigitYearMax = 2012, ToFourDigitYear(99) = 1999

Remarks

Starting with the .NET Framework 4.6, the value of the MinSupportedDateTime property is equivalent to the first moment of March 22, 622 C.E. in the Gregorian calendar. In previous versions of the .NET Framework, it is equivalent to the first moment of March 21, 622 C.E. in the Gregorian calendar. For more information, see "The PersianCalendar class and .NET Framework versions" in the PersianCalendar topic.

622 C.E. is equivalent to the year 0001 in the Persian calendar.
