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.
The following example calls IsLeapYear for five years in each of the eras.
using namespace System; using namespace System::Globalization; int main() { // Creates and initializes a JapaneseCalendar. JapaneseCalendar^ myCal = gcnew JapaneseCalendar; // Displays the header. Console::Write( "YEAR\t" ); for ( int y = 1; y <= 5; y++ ) Console::Write( "\t {0}", y ); Console::WriteLine(); // Checks five years in the current era. Console::Write( "CurrentEra:" ); for ( int y = 1; y <= 5; y++ ) Console::Write( "\t {0}", myCal->IsLeapYear( y, JapaneseCalendar::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 = 1; y <= 5; y++ ) Console::Write( "\t {0}", myCal->IsLeapYear( y, myCal->Eras[ i ] ) ); Console::WriteLine(); } } /* This code produces the following output. YEAR 1 2 3 4 5 CurrentEra: False False False True False Era 4: False False False True False Era 3: False False True False False Era 2: True False False False True Era 1: True False False False True */
