Ever noticed that Halloween pictures always show a full Moon? Well, this year, October 31 brings a Halloween Blue Moon! How rare is a full Moon on Halloween? Let’s learn more about the mythical Moon on this rather mystical night!
A Halloween Blue Moon in October 2020
The next Halloween full Moon occurs this year! We’ll see two full Moons this October: the first occurs on Thursday, October 1, and the second occurs on Saturday, October 31. Halloween’s full Moon will be extra special, since it will be the second of the month and, therefore, a “Blue Moon.”
October’s first full Moon will be called the Harvest Moon, while the second will be the Hunter’s Moon. If you prefer a more creative name, you could call this special full Moon the “Hunter’s Blue Moon on Halloween.”
How Rare Is a Halloween Full Moon?
Despite all the creative Halloween full Moon pictures, a full Moon occurring on Halloween is not a common occurrence and only happens every 18 to 19 years.
Halloween—also known as All Hallows’ Eve—always occurs on October 31; it’s only the day of the week that changes from year to year.
The origin of Halloween itself can be traced back to Samhain (pronounced SOW-in, which rhymes with COW-in), which was an ancient Celtic festival that was celebrated to mark the end of harvesttime. It was also the end of their year and the beginning of the new year, so it was “in between” the two years. It’s said that the spirits of the dead wander around during this time in the moonlight.

A New Moon on Halloween
For a truly spooky night, look to the new Moon, when darkness reigns. During this Moon phase, the lunar disk goes black, so the night appears “moonless.” Of course, the Moon is there, but it’s not lit up by the Sun due to its position in its orbit. See more about the so-called dark side of the Moon.
The Moon will be between 0% and 1% illumination on Halloween in 2024, depending on your timezone. See our Moon Phase Calendar—customized by zip code.
The Black Moon
An even rarer oddity is a “Black Moon.” Although this is not technically an astronomical term, “Black Moon” has come to mean the second new Moon in a calendar month. (It’s somewhat the opposite of a “Blue Moon,” which is popularly defined as the second full Moon in a month.) Read more about the Black Moon.
First Full Moon After Halloween
The first full Moon after Halloween is November’s Moon, which is traditionally called the Full Beaver Moon. According to the Algonquin tribes (and early colonists), this was the time to set beaver traps before the swamps froze, to ensure a supply of warm winter furs.
If you carefully observe nature, you might notice that there are certainly patterns and traditions that happen during the first full Moon after Halloween.
