When overridden in a derived class, determines whether the specified year in the specified era is a leap year.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- year
-
Type:
System::Int32
An integer that represents the year.

-
Type:
System::Int32
An integer that represents the era.
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | year is outside the range supported by the calendar. -or- era is outside the range supported by the calendar. |
To make up for the difference between the calendar year and the actual time that the earth rotates around the sun or the actual time that the moon rotates around the earth, a leap year has a different number of days from a standard calendar year. Each Calendar implementation defines leap years differently.
Notes to Inheritors:
The derived class must support CurrentEra when it is passed as the era parameter. One way to support CurrentEra is by replacing it with the value stored in Eras[0], which is the value for the current era of the calendar.
