Hinweise
Der gregorianische Kalender umfasst zwei Zeiträume: v. Chr. (vor Christus) bzw. v. u. Z. (vor unserer Zeitrechnung) und n. Chr. (nach Christus) bzw. u. Z. (unserer Zeitrechnung). Die vorliegende Implementierung der GregorianCalendar-Klasse umfasst nur den Zeitraum nach Christi Geburt (n. Chr. bzw. u. Z.).
Ein Schaltjahr ist im gregorianischen Kalender als ein Jahr definiert, das ohne Rest durch 4 teilbar ist, sofern es nicht durch 100 teilbar ist. Bei Jahren, die durch 400 teilbar sind, handelt es sich jedoch ebenfalls um Schaltjahre. So war das Jahr 1900 im Gegensatz zum Jahr 2000 z. B. kein Schaltjahr. Ein Gemeinjahr hat 365 und ein Schaltjahr 366 Tage.
Der gregorianische Kalender besteht aus 12 Monaten mit je 28 bis 31 Tagen: Januar (31 Tage), Februar (28 oder 29 Tage), März (31 Tage), April (30 Tage), Mai (31 Tage), Juni (30 Tage), Juli (31 Tage), August (31 Tage), September (30 Tage), Oktober (31 Tage), November (30 Tage) und Dezember (31 Tage). Der Februar hat während eines Schaltjahres 29 und während eines Gemeinjahres 28 Tage.
Jede CultureInfo unterstützt eine Gruppe von Kalendern. Die Calendar-Eigenschaft gibt den Standardkalender für die Kultur an, und die OptionalCalendars-Eigenschaft gibt ein Array mit allen von der Kultur unterstützten Kalendern an. Um den von einer CultureInfo verwendeten Kalender zu ändern, legen Sie die Calendar-Eigenschaft von CultureInfo.DateTimeFormat auf einen neuen Calendar fest.
GetEra ignoriert die Interpunktion in abgekürzten Zeitraumnamen nur dann, wenn der GregorianCalendar in DateTimeFormatInfo.Calendar ausgewählt ist und die Kultur "A.D." als Namen des Zeitraums verwendet, d. h., "A.D." ist äquivalent zu "AD".
Beispiel
Im folgenden Codebeispiel wird veranschaulicht, dass DateTimeFormatInfo die Interpunktion im Namen des Zeitraums nur dann ignoriert, wenn es sich um den gregorianischen Kalender handelt und die Kultur den Zeitraumnamen "A.D." verwendet.
