The Metonic cycle, by strategically inserting seven leap months over its 19-year span, minimizes the drift between lunar and solar cycles.
-
Leap Year Determination
Within the 19-year Metonic cycle, specific years are designated as leap years. Years 3, 6, 8, 11, 14, 17, and 19 of the cycle receive an additional month, Adar I, inserted before the regular month of Adar, which then becomes Adar II. This precisely structured insertion ensures the long-term alignment of the Hebrew calendar with the seasons.
