I've actually worked out, on the computer, the least-erroneous way of doing this. It's actually three Metonic cycles, one of which is one day different in length than the other two. 57 years = 705 months = 20819 days. Quoting from my thread-starting "Survey(?) of ConLangs' Calendars and Colors and Kinterms" post: "Mine will use a lunisolar calendar with a cycle that is 57 years long, and 705 months long, and 20819 days long. Some months will be 29 days and some will be 30 days; some years will be 12 months and some will be 13 months; so some years will be 354 days, some will be 355 days, some will be 383 days, and some will be 384 days. Every 57 years = 705 months = 20819 days, everything will synch-up again." Tom H.C. in MI
