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

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

public override bool IsLeapMonth(
	int year,
	int month,
	int era
)

Parameters

year
Type: System.Int32

An integer that represents the year.

month
Type: System.Int32

An integer from 1 to 12 that represents the month.

era
Type: System.Int32

An integer that represents the era.

Return Value

Type: System.Boolean
This method always returns false.

ExceptionCondition
ArgumentOutOfRangeException

era is outside the range supported by this calendar.

-or-

year is outside the range supported by this calendar.

-or-

month is outside the range supported by this calendar.

In every 30-year cycle that ends with a year that is evenly divisible by 30, the 2nd, 5th, 7th, 10th, 13th, 16th, 18th, 21st, 24th, 26th, and 29th years are leap years. A common year has 354 days and a leap year has 355 days.

A leap month is an entire month that occurs only in a leap year. The Hijri 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 SamplesHijriCalendar  {

   public static void Main()  {

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

      // Checks all the months in five years in the current era. 
      int iMonthsInYear;
      for ( int y = 1421; y <= 1425; y++ )  {
         Console.Write( "{0}:\t", y );
         iMonthsInYear = myCal.GetMonthsInYear( y, HijriCalendar.CurrentEra );
         for ( int m = 1; m <= iMonthsInYear; m++ )
            Console.Write( "\t{0}", myCal.IsLeapMonth( y, m, HijriCalendar.CurrentEra ) );
         Console.WriteLine();
      }

   }

}
