Keterangan

Properti Day mengembalikan nilai yang valid hanya jika IsFixedDateRule properti adalah true.

Nilai Day properti sesuai dengan nilai day parameter CreateFixedDateRule metode . Jika nilainya lebih besar dari jumlah hari dalam bulan transisi, transisi terjadi pada hari terakhir dalam sebulan.

Properti Day menunjukkan hari dalam sebulan di mana aturan tanggal tetap diterapkan (misalnya, 15 April). Sebaliknya, DayOfWeek properti menunjukkan hari dalam seminggu di mana aturan tanggal mengambang diterapkan (misalnya, Minggu kedua November).
