I know that Halloween in 2020 will be different for a lot of reasons - but the first legit October 31st full moon since 2001 is a pretty cool reason
From FarmersAlmanac.com
For more than half a century, whenever two full Moons appear in a single month (which happens on average every 2 1/2 to 3 years), the second full Moon is christened a“Blue Moon.”
When you look at the full Moon on Halloween night, it won’t appear blue in color but you’ll be looking at something pretty uncommon. A full Moon on Halloween occurs roughly once every 19 years—a pattern known as theMetonic Cycle.

According to astronomers, we will all see a 100%-illuminated Halloween full Moon (after 2020) in the years 2039, 2058, 2077, and 2096 (note the 19-year pattern). The good news is that even if the Moon is a day or two away from 100% full on any particular Halloween, it can still serve the purpose for a spooky backdrop since most people can’t tell the difference between a 98% illuminated Moon and a 100% “full” Moon (Cases in point: November 2, 2029, and October 30, 2031). Plan your costumes accordingly!
