Exceptions

Examples

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

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Creates and initializes a JapaneseCalendar.
   JapaneseCalendar^ myCal = gcnew JapaneseCalendar;
   
   // Checks all the months in five years in the current era.
   int iMonthsInYear;
   for ( int y = 1; y <= 5; y++ )
   {
      Console::Write( " {0}:\t", y );
      iMonthsInYear = myCal->GetMonthsInYear( y, JapaneseCalendar::CurrentEra );
      for ( int m = 1; m <= iMonthsInYear; m++ )
         Console::Write( "\t {0}", myCal->IsLeapMonth( y, m, JapaneseCalendar::CurrentEra ) );
      Console::WriteLine();

   }
}

Remarks

Leap years in the Japanese 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 Japanese calendar does not have any leap months.
