TaiwanCalendar.IsLeapMonth Method (Int32, Int32, Int32)

Determines whether the specified month in the specified year in the specified era is a leap month.

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

public override bool IsLeapMonth (
	int year,
	int month,
	int 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.

using System;
using System.Globalization;


public class SamplesTaiwanCalendar  {

   public static void Main()  {

      // Creates and initializes a TaiwanCalendar.
      TaiwanCalendar myCal = new TaiwanCalendar();

      // Checks all the months in five years in the current era.
      int iMonthsInYear;
      for ( int y = 90; y <= 94; y++ )  {
         Console.Write( "{0}:\t", y );
         iMonthsInYear = myCal.GetMonthsInYear( y, TaiwanCalendar.CurrentEra );
         for ( int m = 1; m <= iMonthsInYear; m++ )
            Console.Write( "\t{0}", myCal.IsLeapMonth( y, m, TaiwanCalendar.CurrentEra ) );
         Console.WriteLine();
      }

   }

}
