Blue Moon

Nancy and the Gleaner pointed out that this December is a rarity in that there are two full moons that fall within it. Depending on which definition you use the second full moon, which occurs on New Year's Eve, could be considered a Blue Moon. Another definition only considers a moon 'blue' when it occurs for the fourth time in one season of the year. In that case the fourth moon of any season is considered a Blue Moon. For the next instance of that definition you'll have to wait until November 21st next year. A Blue Moon for my birthday, sweet.

The terminology is not literal; it does not refer to a moon that appears blue. The origin of the term 'blue' moon is debated and that friggin' wiki doesn't give me any answers. It did reveal this much though; the Blue Moon, under any of the various definitions, is indeed rare and that is where the term 'Once in a Blue Moon' comes from. The more you know.

And the more you drink the more you think you are as cool as Dean Martin:

Pace out.
