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.
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(); } } /* This code produces the following output. 1421: False False False False False False False False False False False False 1422: False False False False False False False False False False False False 1423: False False False False False False False False False False False False 1424: False False False False False False False False False False False False 1425: False False False False False False False False False False False False */
