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.

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      ' Creates and initializes a HebrewCalendar.
      Dim myCal As New HebrewCalendar()

      ' Displays the header.
      outputBlock.Text &= "YEAR" + ControlChars.Tab
      Dim y As Integer
      For y = 5761 To 5765
         outputBlock.Text += String.Format(ControlChars.Tab + "{0}", y)
      Next
      outputBlock.Text &= vbCrLf

      ' Checks five years in the current era.
      outputBlock.Text &= "CurrentEra:"
      For y = 5761 To 5765
         outputBlock.Text += String.Format(ControlChars.Tab + "{0}", myCal.IsLeapYear(y, HebrewCalendar.CurrentEra))
      Next
      outputBlock.Text &= vbCrLf

      ' Checks five years in each of the eras.
      Dim i As Integer
      For i = 0 To myCal.Eras.Length - 1
         outputBlock.Text += String.Format("Era {0}:" + ControlChars.Tab, myCal.Eras(i))
         For y = 5761 To 5765
            outputBlock.Text += String.Format(ControlChars.Tab + "{0}", myCal.IsLeapYear(y, myCal.Eras(i)))
         Next 
         outputBlock.Text &= vbCrLf
      Next 
   End Sub 
End Class 
'This code produces the following output.
