Il ToDateTime metodo è utile perché può convertire qualsiasi data nel calendario corrente in una data del calendario gregoriano.The ToDateTime method is useful because it can convert any date in the current calendar to a Gregorian calendar date. La data gregoriano può essere successivamente utilizzata, ad esempio, per confrontare le date in calendari diversi o creare una data equivalente in un determinato calendario.The Gregorian date can subsequently be used, for example, to compare dates in different calendars or create an equivalent date in a particular calendar.
