Examples

下面的示例在每个纪元的五年中,为第二个月(2月)的最后一天调用 IsLeapDayThe following example calls IsLeapDay for the last day of the second month (February) for five years in each of the eras.

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Creates and initializes a KoreanCalendar.
   KoreanCalendar^ myCal = gcnew KoreanCalendar;
   
   // Creates a holder for the last day of the second month (February).
   int iLastDay;
   
   // Displays the header.
   Console::Write( "YEAR\t" );
   for ( int y = 4334; y <= 4338; y++ )
      Console::Write( "\t {0}", y );
   Console::WriteLine();
   
   // Checks five years in the current era.
   Console::Write( "CurrentEra:" );
   for ( int y = 4334; y <= 4338; y++ )
   {
      iLastDay = myCal->GetDaysInMonth( y, 2, KoreanCalendar::CurrentEra );
      Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, KoreanCalendar::CurrentEra ) );

   }
   Console::WriteLine();
   
   // Checks five years in each of the eras.
   for ( int i = 0; i < myCal->Eras->Length; i++ )
   {
      Console::Write( "Era {0}:\t", myCal->Eras[ i ] );
      for ( int y = 4334; y <= 4338; y++ )
      {
         iLastDay = myCal->GetDaysInMonth( y, 2, myCal->Eras[ i ] );
         Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, myCal->Eras[ i ] ) );

      }
      Console::WriteLine();

   }
}

Remarks

韩语日历中的闰年对应于公历中的相同闰年。Leap years in the Korean calendar correspond to the same leap years in the Gregorian calendar. 公历中的闰年定义为可被四整除的公历年份,但它可被100整除。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. 但是,400可以整除的公历年是闰年。However, Gregorian years that are divisible by 400 are leap years. 一个常见年份有365天,闰年有366天。A common year has 365 days and a leap year has 366 days.

闰日是指仅在闰年发生的日期。A leap day is a day that occurs only in a leap year. 例如,2月29日是唯一的闰日。For example, the 29th day of February is the only leap day.
