January 2018 featured two full moons (on the 1st and 31st), both “super moons,” with the second also featuring a total lunar eclipse visible from the Western US. But given the fact that the time between two consecutive full moons is 29.5 days, and February only has 28 days in a non leap year, January’s full moon boon has led to February’s bust. That’s right, February 2018 has no full moons, and, to add insult to injury, March 2018 has two full moons. That’s two blue moons in a single year, something that is not rare, but certainly an interesting consequence of our calendar system. The last time February was ripped off in this way was 1999, and the next time it will happen will be 2037. This 19 year “Metonic” cycle is due to a cyclical pattern in solar and lunar calendars. February is definitely not a good month for werewolves – unless you’re trying to avoid howling.
