Full Corn Moon

The full Moon for September 2020 is the Full Corn Moon! (This year, the Harvest Moon will be in October instead.) Learn how the Corn Moon got its name—plus, see Moon phase dates, Best Days by the Moon, folklore, and more!

When to See the Full Moon in September 2020

This year, start looking for September’s full Corn Moon just after sunset on Tuesday, September 1, as it rises high and reaches its peak illumination at 1:23 A.M. Eastern Time on Wednesday, September 2.

Not a Harvest Moon This Year

Expecting the Harvest Moon this month? You’re not alone!

The full Moon that happens nearest to the autumnal equinox (September 22 or 23) always takes on the name “Harvest Moon” instead of a traditional name—a rule that often places the Harvest Moon in the month of September. However, when September’s full Moon occurs early in the month, the full Moon of early October lands nearest to the autumnal equinox and therefore takes on the Harvest Moon title instead. 

That’s the case in 2020, when October will experience two full Moons: one on October 1 (the Harvest Moon) and the other on the 31st (the Hunter’s Moon and a Blue Moon, too)! Learn more about the Harvest Moon.

Why Is It Called the Corn Moon?

Historically, some Native Americans gave a name to each month’s full Moon, naming it in relation to a natural event or sign of the season. This aided them in tracking the progression of the year. Different peoples had different names, reflecting the areas where they lived.

One such name for the September full Moon was the Full Corn Moon because it traditionally corresponded with the time of harvesting corn in what is now the northeastern United States. It was also called the Barley Moon, as this is the time to harvest and thresh ripened barley. 

Other full Moon names for this month include:

  • Moon When the Plums Are Scarlet” by the Lakota Sioux.
  • Moon When the Deer Paw the Earth” by the Omaha.
  • Moon When the Calves Grow Hair” by the Sioux.

Where Do Full Moons Names Come From?

The tradition of naming Moons is rich in history. Here at The Old Farmer’s Almanac, we have long honored the Native American full Moon names and the folklore of those who came before us. We follow the full Moon names that were used during Native American and Colonial times to help track the seasons—usually by the Algonquin people who were prominent along the Atlantic Coast and into the interior along the St. Lawrence River and around the Great Lakes.

Moon Facts & Folklore

  • Usually, the Moon rises about 50 minutes later each day, but around the time of the autumnal equinox, it rises only around 30 minutes later in the United States—even less in Canada.
  • Frost occurring in the dark of the moon kills fruit buds and blossoms, but frost in the light of the moon will not.

Lunar Cycles

I love watching the cycles happen and was provided the opportunity to watch 2 full cycles during the quarantine. I have always been locked in to the moon for some reason. I am a Sagittarius born at 12:17 on 12/19/1963. If anyone has input as to why, I would love to hear it .

Ohio Beautiful Moons

Three beautiful full moons coming-up, Corn Moon, Harvest Moon and Hunter's Moon, here in the Ohio Valley. Just lovely.

What a beauteous sight to behold

Feel so lucky to live in the gorgeous Catalina Mountains in Oro Valley AZ. The moon coming up over these mountains is beyond breathtaking. I can't stop watching, want to sit all nite taking in such a glorious sight. So still, so erie, so peaceful, and always amazed at the brightness of the full moon and the shadows it creates. It is beautiful and bittersweet at the same time. I always think how nature will in the end endure, despite all the havoc we are wreaking to our planet.

Better mental state with a full moon

Not sure how or why this is but when it is a full moon or close to it I always feel a lot happier, optimistic, positive, refreshed etc. Full moons do for whatever reason improve my mental state. Don't know why. I'm sure it has to do with something

Name slaves called the full moon best to run away on.

One full moon was given a special name by slaves that was best for running away light. During the time when the Underground Railway was operating, they had to reach a known destination by moonlight. I can't remember what it was.

Underground Railroad and slaves

I spend my summers in Michigan and not far from Detroit. One of the last "stops" to The Underground Railroad was the border of the US and Ontario, Canada, where they went for their freedom. While there was never significant Canadian trade in African slaves, native nations frequently enslaved their rivals and a very modest number were purchased by colonial administrators and/or rarely by settlers until 1833, when the British Parliament abolished slavery across the British Empire. There is an interesting tour in Detroit that takes you along the journey that the slaves undertook. Until Emancipation, Detroit was a pivotal part of the Underground Railroad, and in the 1800's, a network of abolitionists, or “conductors,” who aided enslaved people seeking freedom. That’s because the city, code-named “Midnight,” provided access to Canada just across the Detroit River. But to answer your question, the migration of slaves or The Underground Railroad did NOT use the light of the full moon, but instead relied on the stars and in particular the North Star. The slaves fleeing slavery were hunted by the light of the full moon..either by bloodhounds and "pattyrollers". But all the FULL MOON names inherited their colloquial names from the Native Americans or First Nation peoples, and NOT slaves or their plight.

Moon gazing

Catherine Boeckmann's picture

Hi Kathy, What a cool idea. I don’t know LA well but here are some ideas: Griffith Observatory overlooking the Hollywood Sign, Point Dume in Malibu and Topanga State Park atop Elephant Rock.

Best view of the moon where you live

Being a moon "lunatic" and with the name Diana (goddess of the moon) I seek high ground when looking for the best (and earliest) moon view, when it appears the largest. Around our neighborhood there are lots of tall trees and some tall buildings that lock me out from viewing until the moon has been up for quite awhile. So I drive up into the hills where I can get an unobstructed view and am as far away from ambient light as possible. With the quiet around me and very little surrounding light I can really bask in the moonview for a long period of time. I recommend it for all you "loonies" out there!

The Full Moon

I always gasp in silent delight and awe when I see the full moon shining outside my window. Especially if I was not looking for it or counting on it, or planning for it. I smile and feel totally optimistic.

Full Moon September 5, 2017

I couldn't sleep so I got and and looked outside at the night sky, WOW ! I saw the most amazing bright orange full moon. It was well worth the lost sleep to behold such a sight. Such a deep, rich orange moon sitting up in our western sky. I would have paid to see such a sight gladly but it was free and amazing. (Thank-you MUM I know you had something to do with me waking up to see this. Thanks for looking down from heaven to Avelyn and me, rest peacefully.) London, Ontario Canada

Red moon

I stepped outside tonight, September 4, 2017, at about 9:30 pm in Hobart, Indiana (a little east of Chicago and Gary) The moon is approximately 30 degrees off the horizon. The striking thing is that it is a beautiful deep orange color. Why is that?

red moon

I saw the red moon to! I live in sturgis MI and saw it around the same time and it was still red at 11:30 pm. I wondered why it was so red I never have seen the moon this color before, I have seen it orange but never red,

Unfortunately, this beautiful red Moon is probably the result of the forest fires in Oregon. The smoke has crossed the continent. It’s very pretty though.

Red Full Corn Moon (September)

It was early evening on Sept. 6 in Upstate NY....I looked out from my backyard deck and on the eastern horizon, I saw the most beautiful full red moon. I took a pic with my mobile camera, but it did not capture the redness of the moon. Gorgeous!!

I'm really in love with the light from the moon, more so than the sun. it feels so energizing in a healthful way...is it possible moon light is better exposure than sun light?

Wondering what happened to

Wondering what happened to the moon last night September 28th 2014. Was watching it go from a very pretty bright to the yellow & then to the blood red, It was only a crest moon but it totally changed colors then disappeared so to say. Like an eclipse but it never showed back up.? Did anyone else see it last night? 9 to 10 PMT (cst) color
changing then total dark @ 10 or just after. Looked for it all way up to 1 am.

Jeni, i was wondering exactly
