So…I have thought that the definition of a blue moon is the occurrence of two full moons in the same month, which would mean we would have a blue moon this month.  While apparently this is a commonly held assumption, health coach & all around lovely lunar goddess Samantha Honey Pollock posted a link on her Facebook page to the Farmers Almanac/ Wikipedia definition of a blue moon, which is four full moons in the same season.  According to this definition, the next blue moon will occur in August 2013!
