It's the second full moon in one month. They are rare ("once in a blue moon") because the moon goes through it's cycle every 30 days (from full moon to new moon and back). In order to have a blue moon, the 1st of a 31 day month must have a full moon in order to, 30 days later, have a blue moon.

According to modern folklore, a Blue Moon is the second full moon in a calendar month. Usually months have only one full moon, but occasionally a second one sneaks in. Full moons are separated by 29 days, while most months are 30 or 31 days long; so it is possible to fit two full moons in a single month. This happens every two and a half years, on average.
