In 2006,
Sky and Telescope writers Donald Olson, Richard Fienberg and Roger
Sinnott tracked down the origin of the definition of "blue moon." The
traditional definition of a blue moon is based on guidelines in the
Maine Farmers’ Almanac, which relies on the tropical year -- from one
winter solstice to the next -- rather than the traditional calendar
year. Usually a tropical year will feature 12 full moons, with three in
each season, but occasionally, a tropical year will contain 13 full
moons, and one season will have an extra.
