Where did the phrase 'once in a blue moon' come from? A folklorist traces the convoluted evolution of the phrase, while discussing why it adopted the many meanings it has throughout history.
Defining the Original Blue Moon. The correct, original definition is that a Blue Moon is the third full Moon in an astronomical season with four full Moons. A normal year has four astronomical seasons-spring, summer, fall (autumn), and winter-with three months and normally three full Moons each.here are two definitions of a Blue Moon in astronomy; both are a type of full moon. If the moon actually looks blue, it's caused by a rare type of dust in the atmosphere. The Mt. Karaktoa-eruption caused blue moons. When Mt. Karaktoa erupted in 1883, the moon looked blue.
