There is only a full moon on Halloween three or four times per century.
A large full moon would certainly create the perfect atmosphere for a spooky night. However, it turns out that a full moon rarely happens on Halloween. According to The Old Farmers Almanac, a “full moon on Halloween only occurs roughly once every 19 years.
If the full moons are calculated using Greenwich Mean Time, that translates to approximately three to four times per century.” Lucky for us, a full moon is expected for Halloween 2020.
