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.

The following code example calls IsLeapYear for five years in each of the eras.

using System;
using System.Globalization;


public class SamplesHebrewCalendar  {

   public static void Main()  {

      // Creates and initializes a HebrewCalendar.
      HebrewCalendar myCal = new 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();
      }

   }

}
