Who Knew?

There will be a blue moon on New Year's Eve. But it has nothing to do with the color of our celestial neighbor. "Blue moon" refers to the second full moon in a month. And because a full moon occurs every 29.5 days, every two years there will be an additional moon with New Year's Eve getting one every 19 years. Did that make sense? If not, read it again. I did at least four or five times.
