• February is the only month that doesn't have enough room for two full moons, and it's the only month where it's possible to have no full moon at all. In years where February has no full moon - such as in 2018, and nineteen years later in 2037 - January and March both feature two full-moon months.
• Moon facts at your fingertips
• In the nineteen-year lunar cycle, seven out of nineteen years harbor a blue moon, given that we define the blue moon as the second of two full moons to occur in a single calendar month. Only in years where February has no full moon at all will you have two blue moons in the same calendar year.
• After August 2012, we won't see two full moons occurring in a single calendar month again until July 2015. In the meantime, don't forget to enjoy the first of the month's two full moons tonight, as this lovely August full moon lights up the nighttime from dusk until dawn!
