August 2012 is going to have a blue moon! The second full moon in the same month is called a “Blue Moon”, though the origin of the name is uncertain. Some believe it connects from Old English folklore, coming from the word “Belewe” meaning “betray” because it “betrayed” the usual perception of having only one full moon a month. So celebrate the occasion that only comes “once in a blue moon” on the 31st.

Eevzdrop about it.
