Examples
The following 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 TaiwanCalendar.
TaiwanCalendar^ myCal = gcnew TaiwanCalendar;
// Checks all the months in five years in the current era.
int iMonthsInYear;
for ( int y = 90; y <= 94; y++ )
{
Console::Write( " {0}:\t", y );
iMonthsInYear = myCal->GetMonthsInYear( y, TaiwanCalendar::CurrentEra );
for ( int m = 1; m <= iMonthsInYear; m++ )
Console::Write( "\t {0}", myCal->IsLeapMonth( y, m, TaiwanCalendar::CurrentEra ) );
Console::WriteLine();
}
}

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