When a single month has two full moons, the second full moon is called a Blue Moon. It happens every 2-3 years.
Originally, the Maine Farmer's Almanac defined a "blue moon" as the 13th moon in a tropical year(from winter solstice to winter solstice). Normally, each season would consist of 3 moons. In a season of 4 moons, the third would be considered blue. Blue ink was used to record this event in the almanac.
As a reference to the event, though, the idiom "once in a blue moon" means rarely. There is no set amount of time.
