Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)

'Declaration
Public Overrides Function IsLeapMonth ( _
	year As Integer, _
	month As Integer, _
	era As Integer _
) As Boolean
'Usage
Dim instance As TaiwanCalendar
Dim year As Integer
Dim month As Integer
Dim era As Integer
Dim returnValue As Boolean

returnValue = instance.IsLeapMonth(year, month, era)
public boolean IsLeapMonth (
	int year, 
	int month, 
	int era
)
public override function IsLeapMonth (
	year : int, 
	month : int, 
	era : int
) : boolean

Parameters

year

An integer that represents the year.

month

An integer from 1 to 12 that represents the month.

era

An integer that represents the era.

Return Value

This method always returns false, unless overridden by a derived class.

Exception typeCondition

ArgumentOutOfRangeException

year is outside the range supported by the calendar.

-or-

month is outside the range supported by the calendar.

-or-

era is outside the range supported by the calendar.

Leap years in the Taiwan calendar correspond to the same leap years in the Gregorian calendar. A leap year in the Gregorian calendar is defined as a Gregorian year that is evenly divisible by four, except if it is divisible by 100; however, Gregorian years that are divisible by 400 are leap years. A common year has 365 days and a leap year has 366 days.

A leap month is an entire month that occurs only in a leap year. The Taiwan calendar does not have any leap months.

The following code example calls IsLeapMonth for all the months in five years in the current era.
