Double-Blue-Moon years 1600-9999 -------------------------------- m = month of first Blue Moon n = month of second Blue Moon If m=12 then the year refers to the SECOND Blue Moon, and the first Blue Moon occurred in December of the PREVIOUS year. Columns A to S: Metonic cycle to which the year (module 19) belongs. Hence, 'E 05' means that (year mod 19) = 4, and this is the fifth Metonic cycle (5 * 19 = 95 years) since the first Double-Blue-Moon years with that letter.
