Public Overrides Function IsLeapYear (year As Integer, era As Integer) As Boolean

Parameters

year: Int32

An integer that represents the year.

era: Int32

An integer that represents the era. Specify either HebrewEra or HebrewCalendar.Eras[Calendar.CurrentEra].

Returns

Boolean

true if the specified year is a leap year; otherwise, false.

Examples

The following code example calls IsLeapYear 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;
   
   // 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++ )
      Console::Write( "\t {0}", myCal->IsLeapYear( y, 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++ )
         Console::Write( "\t {0}", myCal->IsLeapYear( y, myCal->Eras[ i ] ) );
      Console::WriteLine();

   }
}

Remarks

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.
