once in a blue moon

Have you ever heard the phrase "once in a blue moon"? You know... something that rarely happens. Have you ever wondered where it originated? Is there such a thing as a "blue" moon?

Actually, yes, there is. And one is going to happen this year!

That's right. This Dec. 31st is going to be a blue moon. Oh, not literally, of course.

A blue moon is a second full moon in the same month. For more information on the blue moon, go here.

It's interesting what you can learn if you just ask the right questions. :)

Until next time...
