Longest Jewish year
This year, 5779, is the longest possible year on the Jewish calendar. Not only is it a leap year, but Cheshvan and Kislev both have 30 days, for a total of 385 days. How often does that happen?

Could you add something about how you arrived at (or sourced) that number?

Where do you get 1371/8512 from? My reading of the Tur’s chart gives 40/247, which is slightly off but still rounds to 16.1%. Where does the difference come from? (And what does 8512 represent? I know of 19 year cycles, 247 year cycles, and over 600K year cycles, but 8512 is new to me.)

Ah, makes sense now. So 8512 doesn’t mean anything in particular, that’s just the most reduced fraction?
