Milo, 405 lunations or synodic months are 11959.88...
or practically 11960 lunations, as I already told you
several times, and how this value can be found: start
with the Stone Age way of laying out 30 29 30 29 30 29
30 29 30 29 30 ... pebbles for as many days in 1 2 3 4 5
6 7 8 9 10 11 ... lunations. 15 and 17 lunations counted
that way yield 443 and 502 days respectively. Now add up
15 17 15 17 15 17 lunations, and you get 443 945 1347 1890
2392 days for 17 32 49 64 81 lunations. Take 2392 days for
81 lunations, multiply the numbers by a factor of 5 and
you obtain 11680 days for 405 lunations.
