The Hebrew calendar recognizes two eras: B.C.E. (before the common era) and A.M. (Latin "Anno Mundi", which means "the year of the world"). This implementation of the HebrewCalendar class recognizes only the current era (A.M.) and 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 Hebrew calendar has 12 months during common years and 13 months during leap years:

The days in Cheshvan and Kislev vary depending on the placement of Jewish holidays. During leap years, Adar is replaced by Adar Alef with 30 days and Adar Beit with 29 days. Adar Beit is considered the leap month. The last day of Adar Alef and all the days in Adar Beit are considered leap days.

The date January 1, 2001 A.D. in the Gregorian calendar is equivalent to the sixth day of Tevet in the year 5761 A.M. in the Hebrew calendar.

Each CultureInfo object supports a set of calendars. The CultureInfo.Calendar property returns the default calendar for the culture, and the CultureInfo.OptionalCalendars property returns an array containing all the calendars supported by the culture. To change the calendar used by a CultureInfo object, the application can set the Calendar property of CultureInfo.DateTimeFormat to a new Calendar object if the new calendar is one of the culture's optional calendars. The following example shows how to change the calendar for the he-IL culture to the Hebrew calendar.


// Change the calendar used by a he-IL CultureInfo object from Gregorian to Hebrew. 
CultureInfo hebrewCulture = new CultureInfo("he-IL");
Calendar originalCalendar = hebrewCulture.Calendar;
string message = null;

// Confirm that the default calendar is not the Hebrew calendar.
if (originalCalendar.ToString() != "System.Globalization.HebrewCalendar")
{
   // Check whether the culture supports the Hebrew calendar.
   bool supported = false;
   foreach (Calendar supportedCal in hebrewCulture.OptionalCalendars)
   {
      if (supportedCal.ToString() == "System.Globalization.HebrewCalendar")
      {
         supported = true;            
         hebrewCulture.DateTimeFormat.Calendar = supportedCal;
         message = String.Format("Changed the current calendar for the {0} culture from {1} to {2}.",
                                 hebrewCulture.ToString(),
                                 originalCalendar.ToString().Replace("System.Globalization.", ""),
                                 supportedCal.ToString().Replace("System.Globalization.", ""));                                 
         break;
      }
   }
   if (! supported) message = "The Hebrew calendar is not supported.";
}       
else
{
   message = String.Format("Hebrew is the default calendar for the {0} culture.",
                           hebrewCulture.ToString());
}
outputBlock.Text += message + "\n";
// The example displays the following output:
//   Changed the current calendar for the he-IL culture from GregorianCalendar to HebrewCalendar.
