Here is what I found on Wikipedia:

A blue moon is an extra full moon that appears in a subdivision of a year, either the third of four full moons in a season or, recently, a second full moon in a month of the common calendar. Metaphorically, a “blue moon” is a rare event, as in the expression “once in a blue moon”.

The phrase has nothing to do with the actual color of the moon, although a literal “blue moon” (the moon appearing with a tinge of blue) may occur in certain atmospheric conditions; e.g., when there are volcanic eruptions or when exceptionally large fires leave particles in the atmosphere.

Two full moons in one month.

A blue moon is the second full moon in a month, if there is one.

I don’t know, but it saw me standing alone, without a love of my own.
