Population Statistic: Read. React. Repeat.
Wednesday, December 30, 2020

I’m sure it’s a good omen that 2010 will ring in with a rare blue moon, or second full moon within a calendar month.

What’s more interesting is how the popular term “blue moon” came about:

The popular definition of blue moon came about after a writer for Sky & Telescope magazine in 1946 misinterpreted the Maine Farmer’s Almanac and labeled a blue moon as the second full moon in a month. In fact, the almanac defined a blue moon as the third full moon in a season with four full moons, not the usual three. Though Sky & Telescope corrected the error decades later, the definition caught on.

Thus born out of error, it really should be called a “blew moon”. At least then we all wouldn’t be straining out necks to see the non-existent bluish hue that you’d expect.
