Calendar.GetLeapMonth Method (Int32, Int32)
Calculates the leap month for a specified year and era.
Assembly: mscorlib (in mscorlib.dll)
Return ValueType: System.Int32
A positive integer that indicates the leap month in the specified year and era.
Zero if this calendar does not support a leap month or if the year and era parameters do not specify a leap year.
In a calendar that supports the notion of a leap month, the leap month can occur either after a particular month or after any month in a year. For example, the GetMonth(DateTime) method returns a number between 1 and 13 that indicates the month associated with a specified date. If there is a leap month between the eighth and ninth months of the year, the GetMonth(DateTime) method returns 8 for the eighth month, 9 for the leap eighth month, and 10 for the ninth month.
