Asked in Space Travel and Exploration
How many full moons are in a year?
-- Always at least 12.
-- If the first one occurs by January 10th, then there's enough time left
in that calendar year for 12 more, for a total of 13.
Stated another way:
All of the moon's phases seen during the first 10 days of January will occur 13 times in that year.
All of the others will occur 12 times in that year.
