  • The Metonic cycle is a cycle of 19 tropical years – conventionally equated to 235 synodic months – in which the moon returns to almost the same apparent position relative to the sun, so that new and full moons occur at the same dates in the corresponding year of each cycle.

    It was widely adopted in eastern lunisolar calendars, and was the basis of the early Christian calculation of the date of Easter.
