Where did the phrase 'once in a blue moon' come from? A folklorist traces the convoluted evolution of the phrase, while discussing why it adopted the many meanings it has throughout history.
The error led to the widely accepted definition of blue moon today: the second full moon in a given month. A blue moon occurs roughly once every 2.7 years. The next blue moon, according to this folklore, will be July 31, 2015, following a full moon on July 1, 2015.
