Commenti

Sebbene il valore della MinSupportedDateTime proprietà sia il primo istante del 1 ° gennaio 0001 e.v., il calendario gregoriano non è stato introdotto fino al 15 ottobre 1582 e la relativa adozione nel continente europeo e in tutto il mondo è stato lento.Although the value of the MinSupportedDateTime property is the first moment of January 1, 0001 C.E., the Gregorian calendar was not introduced until October 15, 1582, and its adoption throughout the European continent and worldwide was slow. Fino a quando non hanno adottato il calendario gregoriano, la maggior parte delle impostazioni cultura nei continenti europei, americani ed australiali usava il calendario Giuliano JulianCalendar , rappresentato dalla classe.Until they adopted the Gregorian calendar, most cultures in the European, American, and Australian continents used the Julian calendar, which is represented by the JulianCalendar class.
