Commenti

Ad esempio, in HebrewCalendar, GetMonthsInYear restituisce 12 per un anno comune o 13 per un anno bisestile.

Note per gli implementatori

La classe derivata deve supportare CurrentEra quando viene passata come era parametro. Un modo per supportare CurrentEra è sostituendolo con il valore archiviato in Eras[0], che è il valore per l'era corrente del calendario.
