Açıklamalar

DayOfWeek özelliği yalnızca özelliği ise IsFixedDateRulefalsegeçerli bir değer döndürür.

DayOfWeek özelliği, kayan tarih kuralının uygulandığı haftanın gününü gösterir (örneğin, Kasım ayının ikinci Pazar günü). Buna karşılık özelliği, Day sabit tarih kuralının uygulandığı ayın gününü gösterir (örneğin, 15 Nisan).

Şunlara uygulanır
