The rarity of 2020’s Halloween full moon – Deseret News

Halloween 2020 is going to be extra special, at least astrologically.

For the first Halloween since 1944, nearly all the world’s time zones will experience a full moon.

Because of the Metonic Cycle, a full moon appears in some parts of the world — but not most parts — on Halloween every 19 years. (In 2001, for example, the United States’ Central and Pacific time zones experienced a Halloween full moon.) But after 1944, the Metonic Cycle shifted the full moon a day forward to Nov. 1 (in the years 1963, 1982 and 2001) for most locations, according to the Farmers’ Almanac.

Not everyone will get a Halloween full moon this Oct. 31. If you live in Central Australia, Eastern Australia, New Zealand, Eastern Indonesia, New Guinea, Japan, Fiji or Eastern Russia, you’ll narrowly miss the Halloween full moon.

“Every time zone has it except those east of (GMT) +8 time zones if they have daylight time, or (GMT) +9 with no daylight time,” astronomy educator Jeffrey Hunt wrote, according to CNET.
