what is a blue moon and how often does it happen?
In: Physics
It happens once in a blue moon… Sorry.
A blue moon is an additional full moon that appears in a subdivision of a year: either the third of four full moons in a season, or a second full moon in a month of the common calendar.
It has nothing to do with the color.
To answer your ‘how often’ question literally 1.16699016e-8hz is the frequency of a blue moon. Or once every thousand days.
I sourced my info from two google searches.
