What is a blue moon?
A blue moon does not refer to the Moon’s color. Instead, it is a term used for the second full moon within the same month.
Most years have twelve full moons-one each month. A lunar month is about 29.5 days –from one full moon to the next. A year with 12 full moons has about eleven extra days each year. These extra days add up, so about every two or three years there is an extra full moon. YEP! this is what is called a blue moon.
