Opmerkingen
De waarde van de MaxSupportedDateTime eigenschap is het laatste moment van 31 december 9999 C.E. in de Gregoriaanse kalender. In het .NET Framework 4.6 is deze waarde gelijk aan de 13e dag van de 10e maand van het jaar 9378 in de Perzische kalender. In eerdere versies van het .NET Framework is het gelijk aan de tiende dag van de 10e maand van het jaar 9378 in de Perzische kalender. Zie 'The PerzischCalendar-klasse en .NET Framework-versies' in het onderwerp PersianCalendar voor meer informatie.
9999 C.E. is gelijk aan het jaar 9378 in de Perzische kalender.
