The full moon occurs once every 29.5 days. This essentially means that there is one full moon every month. However, as we know, every month but February has at least 30 days in it, which presents the potential for two full moons in a month.
Mary Runyon in Pike Co., KY took this shot of the nearly full moon the other night.
August 2012 - is one of these unique months, which will have two full moons. There will be a full moon on August 2nd, and then another full moon on August 31st.
So those of us whom are superstitious in regards to full moons will have two special days in August of 2012.
The term Blue Moon can refer to the second full moon in a given month. When people say "once in a blue moon" they are speaking to the rarity of the occurrence of a second moon happening in the same given month.
