However our month-to-month calendar, primarily based on Earth’s orbit across the Solar, does not neatly match with the lunar cycle, and so some years we’ve got 13 full Moons.

Because of this typically we get two full Moons in a calendar month, and that is the casual definition of a blue Moon.

The older, extra conventional which means of a blue Moon is said to the astronomical season.

An astronomical season is the time frame between a solstice and an equinox.

Within the northern hemisphere, summer season solstice (round 20–22 June) marks the beginning of astronomical summer season.

Three months later, autumn equinox (round 21–23 September) marks the beginning of astronomical autumn.

Inside that point, often we’d see three full Moons.

The Maine Farmers’ Almanac definition of a blue Moon is that it is the third full Moon in a quarterly season of 4 full Moons.

It is a seasonal blue Moon, and is the definition most popular by many astronomers.
