==Etymology==
A blue moon is the appearance of the third full moon in a season that has four full moons, instead of the usual three. It is never visually blue. Because a blue moon occurs only every two or three years, the term blue moon is used colloquially to mean a rare event, as in the phrase "once in a blue moon".
