A partir de .NET Framework 4.6, el valor de la MinSupportedDateTime propiedad es equivalente al primer momento del 22 de marzo de 622 C.E. en el calendario gregoriano. En versiones anteriores de .NET Framework, equivale al primer momento del 21 de marzo de 622 C.E. en el calendario gregoriano. Para obtener más información, vea "La clase PersianCalendar y las versiones de .NET Framework" en el PersianCalendar tema.

622 C.E. equivale al año 0001 del calendario persa.
