Examples

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();

   }
}

Remarks

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.
