This one's pretty cool since it's happening on the last day of the year and all. Although, by definition, they can only happen in the last few days of the month, so it's a little less special than I first thought. I also remember a few years back, there were two blue moons only two months apart, something that only happens every couple decades. There was a full moon in early January, a blue moon on Jan 31st, then the tiny month of February managed to fit in between full moons, so the next full moon happened on March 1st, with a blue moon later that month.
