There’s A “Blue Moon” Tonight And It Won’t Happen Again For 3 Years
For everyone who has ever said you might do something "once in a blue moon," tonight is your night!
Today brings us the second full moon in a single month.
According to modern folklore, such an event is called a "blue moon."
The moon will not actually be blue, but two full moons in a single month is still a pretty rare event.
So make this blue moon count! Remember: You only blue moon once (in a while).
