Golden number

GOLDEN NUMBER. A term used in the elaborate tables placed at the beginning of the Prayer Book for the finding of Easter. The Golden Number of a year marks its place in a cycle, called the Metonic Cycle (from Meton, an Athenian astronomer B.C. 432), of nineteen years. The year A.D. 1 was fixed as the second year of such a cycle. Hence the rule given to find the Golden Number, viz., "Add one to the year of our Lord, and then divide by 19; the remainder, if any, is the Golden Number; but if there be no remainder, then 19 is the Golden Number."
