Parametry

year
Int32

Rok.

month
Int32

Celé číslo od 1 do 12, které představuje měsíc.

day
Int32

Celé číslo od 1 do 30, které představuje den.

era
Int32

Éra. Zadejte UmAlQuraCalendar.Eras[UmAlQuraCalendar.CurrentEra] nebo UmAlQuraEra.

Návraty

Boolean

trueje-li zadaný den přestupný den; v opačném případě . false Návratová hodnota je vždy false proto, že UmAlQuraCalendar třída nepodporuje přestupné dny.
