Commenti

In GregorianCalendar ,GetDaysInYear ad esempio, restituisce 365 per un anno comune o 366 per un anno bisestile.For example, in GregorianCalendar, GetDaysInYear returns 365 for a common year or 366 for a leap year.

Note per gli eredi

La classe derivata deve supportare CurrentEra quando viene passata era come parametro.The derived class must support CurrentEra when it is passed as the era parameter. Un modo per supportare CurrentEra è sostituirlo con il valore archiviato in ere [0], che corrisponde al valore dell'era corrente del calendario.One way to support CurrentEra is by replacing it with the value stored in Eras[0], which is the value for the current era of the calendar.
