The Corn Moon is the traditional name for the September full moon, tied to the time corn is ready to be gathered. There is one catch: when the full moon nearest the September equinox falls in September, that moon is called the Harvest Moon instead, and the Corn Moon name moves to the September full moon only in years when the Harvest Moon falls in October.

Times are US Eastern Time (ET), when the moon is exactly full or at the exact phase. It looks full for about a night either side.
Drive through farm country in September and you can see why this moon got its name. The corn stands tall and dry, the stalks rustle, and the first combines start working late into the evening under work lights and moonlight.
The Corn Moon belongs to the traditional full moon names popularized by the Old Farmer's Almanac and attributed to Native American and early colonial traditions. It comes with a small naming puzzle that confuses a lot of people: it shares the calendar with the Harvest Moon, the best-known full moon of the year. This page explains which one is which in a given year, where the name comes from, what people take it to mean and how to mark it.
Why is it called the Corn Moon? Origin and other names
Corn, the grain Europeans called maize, was a staple crop across much of North America long before colonization, and late summer to early autumn was the time to harvest it. The name Corn Moon, listed in the Old Farmer's Almanac, is attributed to Native American and early colonial traditions of this season. Some older lists also give Barley Moon, a name from the grain harvest in other regions.
The tricky part is the overlap with the Harvest Moon. By the Almanac's convention, the Harvest Moon is the full moon that falls nearest the September equinox, in late September or early October. So:
- If the Harvest Moon falls in September, that moon takes the Harvest Moon name, and the Corn Moon label is not used for September's full moon that year.
- If the Harvest Moon falls in October, the full moon in September is the Corn Moon.
In other words, the Corn Moon name is the fallback for September, and only appears in years when the Harvest Moon comes late. The table below shows each coming full moon, so you can see which name applies. The names are traditions, not astronomical categories.
When is the Corn Moon and how to see it
The Corn Moon is a September full moon, and it only gets that name in years when the Harvest Moon is the October one. The equinox, when day and night are nearly equal, falls around September 22 or 23, so a full moon in early or mid September sits well before it, and the Corn Moon is typically that earlier one. Check the dates below for how it works out in a given year.
Like every full moon, it rises near sunset, reaches its highest point around midnight and sets near sunrise. In September the Sun is lower than in summer, so the full moon climbs a little higher than the July or August ones, and the delay between one night's moonrise and the next shrinks as the equinox approaches. You will notice the moon coming up in the east shortly after sunset on several evenings in a row, which is the effect that made the Harvest Moon famous.
To see it well, look to the east just after sunset. A flat horizon, such as a field, makes the early moon look large and warm in color.
Corn Moon spiritual meaning: gathering what you planted
The Corn Moon meaning follows the crop. Corn is planted in spring, grows through summer and is gathered in autumn, so it makes a plain, honest symbol of cause and effect over time. People who read the moon symbolically use it to look back at what they planted and what has actually come up.
- Reaping. This is the moon of results, including modest ones. What did your spring intentions turn into? Some seeds produced a lot, some produced a little, and some never came up.
- Gratitude. Harvest is traditionally followed by thanks and shared meals. The moon invites you to name who and what helped.
- Sorting. Part of a harvest is deciding what to keep, what to store and what to leave in the field. The symbol points to choosing deliberately.
- Preparation. Corn is dried and stored for the cold months. You might ask what you need to put aside before winter.
If the year has not gone as planned, this moon is still a useful pause. A harvest can be small and still show you something about the soil, the timing or the seed you chose. The reading is a reflection tool, not a forecast.
Corn Moon rituals: a harvest review and gratitude practice
A harvest theme gives this full moon an easy structure. Here are practices people use.
- The three-column review. On a page, make three columns: planted, grown, gathered. Fill in what you started this year, what actually developed and what you have in hand now.
- Name what to leave in the field. Write one thing that did not ripen and that you are willing to stop tending. Some people burn the paper safely or tear it up.
- Thank someone. Corn was always a shared effort. Send a message to a person who helped you this year, with specifics.
- Cook with the season. Make something with corn, cornbread, a corn salad or fresh cobs on the stove, and eat it with other people if you can.
- Charge crystals. Citrine and tiger's eye are common choices for an abundance theme. People place them on a windowsill under the moon overnight, and it is a custom rather than a demonstrated effect.
- Evening walk. Look for the golden light on the stubble of a cut field.
A quiet half hour with a notebook is enough.
Corn Moon in love and relationships
Harvest imagery fits love easily, because relationships also reward steady tending more than grand gestures. The Corn Moon is often read as a moon for noticing what a relationship has produced over time.
If you are in a relationship, try the harvest review together. Each of you names three things that have grown between you this year, and one thing you want to plant before winter. It can be small: a weekly dinner, a regular call to family, a trip planned for spring. People often find it is easier to talk about what was gathered than about what went wrong.
If you are single, use this moon to look at what you planted and what came up, such as friendships, interests and routines. It can also be a time to notice that you do not need a partner to have a harvest.
If you are healing from a breakup, the harvest includes what you learned, even from something that ended. Some people write down what they would like to keep, such as a new habit or a clearer sense of what they want, and what they are ready to leave behind.
A corn field needs sun, rain and time. So does a relationship, and so do you.
Corn Moon folklore, other harvest names and astrology
Harvest festivals across Europe and North America cluster around the autumn equinox, and the full moon of this season was a practical tool: in the days before electric light, extra moonlight meant extra time in the fields. Whether in a corn field or a barley field, the idea is the same, and it is the root of the better-known Harvest Moon.
The Corn Moon is also part of a chain of names that follows the farm year: Buck Moon in July, Sturgeon Moon in August, Corn or Harvest Moon in September, Hunter's Moon in October. The names are not sacred titles. They are a calendar of what people were doing and seeing, which is why they differ by source and region.
Barley Moon is another name you may meet for the same September moon. If you are tracing a tradition for a particular nation, look for a source from that nation, because the Almanac's list is a popular compilation and not a statement by any one people.
In astrology, the sign of the September full moon varies from year to year with the date. Check the date and an ephemeris for the sign this year.
Frequently asked questions
What is the difference between the Corn Moon and the Harvest Moon?
The Harvest Moon is the full moon nearest the September equinox, in late September or early October. The Corn Moon is the name for September's full moon in years when the Harvest Moon falls in October. So in any given year, September's full moon carries only one of the two names.
Is the Corn Moon every year?
Not under that name. Every year has a September full moon, but it is called the Harvest Moon when it is the one nearest the equinox. The Corn Moon name applies only when that nearest full moon lands in October instead. It can be a few years between Corn Moons, so check the dates below.
Why is it called the Corn Moon?
It is named for the corn harvest, which takes place in late summer and early autumn across much of North America. The Old Farmer's Almanac lists it, attributing the name to Native American and early colonial traditions. It belongs to a calendar of full moon names that follow what people were growing and gathering.
What is the Barley Moon?
Barley Moon is another name that appears in lists for the September full moon, tied to the barley harvest in places where that grain mattered more than corn. It is the same moon as the Corn or Harvest Moon, just with a name from a different crop and region.
What should I do on the Corn Moon?
People commonly use it for a harvest review, which means writing what you planted this year, what grew and what you gathered. Others share a meal, thank someone who helped them, or let go of one project that never ripened. It is a reflection practice, and you can keep it as short as you like.
