Halloween Moon

Halloween Moon: Have you ever noticed that Halloween pictures always show a full moon? Does it happen very often on Halloween? On this rather mystical night, let’s learn more about the mythical Moon!


Despite all the creative Halloween full Moon pictures, a full Moon on Halloween is not an everyday event and only occurs every 18 to 19 years. We last saw a full Moon on Halloween night in 2021, so we won’t see one for a while.

As you know, Halloween always falls on October 31; it’s only the day of the week that changes. Since a lunar cycle lasts about 29.5 days, if there is a full Moon on Halloween, it will also be the second full Moon in October, and, therefore, a Blue Moon!

Uncommon Halloween Blue Hunter’s Moon in 2021

At the point when we think about “All Hallow’s Eve,” a considerable lot of us invoke frightening pictures of werewolves, trolls, zombies, and other startling things that go “knock” in the evening, all illuminated by a creepy full Moon. Be that as it may, how normal is a Halloween full Moon? Obviously, not very.

In 2001, apparitions and trolls in Central and Pacific time zones trick-or-treated by the light of a full Moon, yet a Halloween full Moon hadn’t showed up for everybody in record-breaking zones beginning around 1944!

At the point when you check out the full Moon on Halloween night, it will not seem blue in shading yet you’ll be taking a gander at something pretty exceptional. A full Moon on Halloween happens generally once at regular intervals—an example known as the Metonic Cycle.

This notable lunar cycle was found in 432 BC by the Greek, Meton, of Athens. Not set in stone that following 19 years have passed, the period of the Moon will rehash on a similar date. Well , not generally. As a result of slight varieties in the Moon’s orbital period, and the quantity of jump days that intercede over a 19-year interval of time, the Metonic Cycle can be exact just to inside a day.

For a Halloween full Moon, the Metonic Cycle functioned admirably right off the bat in the twentieth Century—in the years 1925 and 1944.  But from there on, utilizing the cycle, the date of full Moon moved a day to November first (in 1963, 1982, and 2001). However at that point, in 2020, it got back to October 31st. Making it a more uncommon sight, for sure.

But for 2021 on through the balance of the 21st century, a full Moon on Halloween will occur once every 19 years.

Blue Moon Definition

In more than half a century, whenever there are two full Moons on the same day (which happens every two and a half to three years on average), the second full Moon has been called a “blue moon.”

It would always have to be a Blue Moon since the lunar cycle only lasts 29.5 days on October 31st (as it will this year).

There is an alternate definition of the “Blue Moon” – when there are four full Moons in one season, the third one is a “Blue Moon.”


When’s The Next Halloween Full Moon?

Astronomers have predicted that we will all witness 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). Be sure to plan your costumes accordingly!


We Had 2 Supermoons in 2021

We can thank the Moon’s orbit, which is not a perfect circle, but an oval shape, for allowing a Supermoon to occur. When the Moon orbits the Earth each month, it reaches a point called apogee, which is the Moon’s farthest point from the Earth, and a point called perigee, which is the Moon’s closest point to the Earth.

According to how most people define a Supermoon, it occurs when the Moon is at least 90% of the way to its perigee position at the same time it is in its “full” phase.
