Blue Moons Since February has only 28 days, a full lunar cycle did not fit into February, and there was no full moon that month. The next full moon was on March 1, followed by the second blue moon on March 31. Such an event happens about once every 19 years. 3. Where does the term blue moon come from? The term blue moon probably comes from the fact that, on very rare occassions, the moon actually appears to be blue. This usually happens after a volcanic eruption, such as Mount Pinatubo in 1991, when lots of dust is present high in the sky. Other times when the moon turned blue include the eruption of El Chichon in 1982, and Krakatao in 1883. These blue moons are so rare that the phrase once in a blue moon has come to mean a very rare event. The term blue moon was applied to the second full moon in a month due to an error in Sky and Telescope magazine in 1946. Read the gory details from Sky Publishing here.

Blue Moon: The Strange Evolution of a Phrase Farmers' almanacs published in Maine began calling the third full moon in a season with four a blue moon. Theories abound as to why the publishers did this. Some say that third moon was traditionally called blue in the Czech language, while others think the term comes from the French phrase double moon, la deux lune, which sounds like blue moon. Other theories hold that almanacs started out printing the various types of moons in different colors, while still others assert that those third moons were bad luck, thus rendered blue.

Once in a Blue Moon The only month which could miss a Full Moon completely is February. This is most likely to happen in a non-leap year, when February is only 28 days long, but even when it has 29 days, this is still less than the length of the shortest lunar month, so it's possible for any February to miss a Full Moon.
