I think it pretty well follows. Consider the latest possible case, where a
full moon falls late on January 31. February will have no full moon, even
in a leap year, with a 29.5 day sidereal month. That puts the next full
moon on either March 1st or 2nd, and the *next* full moon will fall on
March 30 or 31.
I: 31/01 23:50
plus 29 12:00
60/01 35:50
corr 61/01 11:50
corr -31 (leap year)
30/02 11:50 30/02 11:50
corr -28 -29
II: 02/03 11:50 01/03 11:50
29 12:00 29 12:00
III: 31/03 23:50 30/03 23:50
If the first full moon falls earlier on January 31, the third one will
still be within March...
