Magical things happen once upon a blue Moon. And this Thursday we get a chance to find out just what those magical things as we watch the rare lunar event coincide with all the beautiful fireworks of New Year's Eve.
Blue Moon is the term applied to the second full Moon in a calendar month. It's an event that occurs roughly every two and a half years. This Thursday's blue Moon is far rarer than that though, because it's happening right on New Year's Eve—a coincidence that happens only about once in every twenty years.
PS: No, the Moon doesn't actually turn blue. It's just the term used to describe this lunar event.
