Once in a Blue Moon

You ever hear that phrase? "Once in a blue moon"

It means something rare. And today is one.

A blue moon is the second full moon in a month. Most years have twelve full moons, occur roughly monthly. But each solar calendar year contains an excess of roughly eleven days compared to the lunar year. the extra days accumulate, and every 2 or 3 years, we end up with a thirteenth full moon.

And this year, the Blue Moon happens to be on New Year's Eve, which is even rarer. The next time we'll see this is in 2028.

Happy New Year's everyone! Hope you have cool plans to coincide with the Blue Moon.
