Once in a Blue Moon



When a full moon is not enough to meet a writer's need for the symbolic, they can use the Blue Moon for it's rarity value. They didn't coin the Stock Phrase "Once in a Blue Moon" from nothing now did they.

Now there's been much confusion over what constitutes a Blue Moon.

It actually refers to the third full moon of a season with four full moons, as compared the more frequently used second full moon in the same month. Because blue moons are still known by the latter example, most of the examples below will refer to that one. However, the phrase "once in a blue moon" is much older that either of these usages, and so it appears that the "blue moon" was named for the expression and not vice versa.

You should note that an actual Blue Moon doesn't constitute the astrological term, but the effect can be caused by smoke or dust particles in the atmosphere that's usually caused by a forest fire or volcanic ash, as seen in the Real Life section.

Once in a Blue Moon is a phrase that specifically refers to an unlikely or impossible event happening, usually a One in A Million Chance.
