Remarques

Bien que la valeur de la propriété MinSupportedDateTime soit le premier moment du 1er janvier 0001 (notre ère), le calendrier grégorien n’a pas été introduit jusqu’au 15 octobre 1582 et son adoption sur le continent européen et dans le monde entier était lente.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. Tant qu’ils n’ont pas adopté le calendrier grégorien, la plupart des cultures des continents européens, américain et australien utilisaient le calendrier julien, qui est représenté par la classe JulianCalendar.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.
