2020 has been quite the year and to make Halloween night even spookier than it already is, there will be a rare Blue Moon spotted. The moon will not actually be blue in color, but instead, the name comes from it being the second full moon of the month. This year, October has two full moons, according to the Farmer’s Almanac. The first one will take place on Thursday, October 1st, and the second on All Hallow’s Eve!
Two full moons in one month is not very common and only happens on average every 2 1/2 to 3 years, so we are lucky that Halloween night will be lit up by this rare moon! A blue moon on Halloween is so rare that it only occurs once every 19 years (known as a Metonic Cycle).
The Farmer’s Almanac goes on to talk about how we describe unusual events as “Once in a Blue Moon,” an expression that was “first noted back in 1821 and refers to occurrences that are uncommon, though not truly rare.”
