         for ( int m = 1; m <= iMonthsInYear; m++ )
            Console.Write( "\t{0}", myCal.IsLeapMonth( y, m, HebrewCalendar.CurrentEra ) );

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.

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.
