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 month is an entire month that occurs only in a leap year. In the Hebrew calendar, Adar Beit is the only leap month.

The following code example calls IsLeapMonth for all the months in five years in the current era.


using System;
using System.Globalization;


public class Example
{

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {

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

      // Checks all the months in five years in the current era.
      int iMonthsInYear;
      for (int y = 5761; y <= 5765; y++)
      {
         outputBlock.Text += String.Format("{0}:\t", y);
         iMonthsInYear = myCal.GetMonthsInYear(y, HebrewCalendar.CurrentEra);
         for (int m = 1; m <= iMonthsInYear; m++)
            outputBlock.Text += String.Format("\t{0}", myCal.IsLeapMonth(y, m, HebrewCalendar.CurrentEra));
         outputBlock.Text += "\n";
      }

   }

}
