This implementation of the HebrewCalendar class recognizes only the Hebrew years 5343 to 5999 (1583 to 2239 in the Gregorian calendar).
In every 19-year cycle that ends with a year that is evenly divisible by 19, the 3rd, 6th, 8th, 11th, 14th, 17th, and 19th years are leap years. A common year can have from 353 to 355 days, depending on the placement of Jewish holidays. A leap year can have from 383 to 385 days.
A leap day is a day that occurs only in a leap year. In the Hebrew calendar, the last day of Adar Alef and all the days in Adar Beit are considered leap days.
The following code 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 HebrewCalendar. HebrewCalendar^ myCal = gcnew HebrewCalendar; // Creates a holder for the last day of the second month (February). int iLastDay; // Displays the header. Console::Write( "YEAR\t" ); for ( int y = 5761; y <= 5765; y++ ) Console::Write( "\t {0}", y ); Console::WriteLine(); // Checks five years in the current era. Console::Write( "CurrentEra:" ); for ( int y = 5761; y <= 5765; y++ ) { iLastDay = myCal->GetDaysInMonth( y, 2, HebrewCalendar::CurrentEra ); Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, HebrewCalendar::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 = 5761; y <= 5765; y++ ) { iLastDay = myCal->GetDaysInMonth( y, 2, myCal->Eras[ i ] ); Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, myCal->Eras[ i ] ) ); } Console::WriteLine(); } } /* This code produces the following output. YEAR 5761 5762 5763 5764 5765 CurrentEra: False False False False False Era 1: False False False False False */
