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

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.

Type: System::Boolean

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 namespace System;
using namespace System::Globalization;
int main()
{

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

   }
}
