This year, the Corn Moon takes center stage because the traditional Harvest Moon title shifts to October, making this one extra special.Whether you're a casual stargazer or astronomy enthusiast, this celestial show promises beauty, wonder, and a touch of cosmic poetry.

The Corn Moon: What is it and why the name?

The Corn Moon is the full moon that appears in September, when it isn't the Harvest Moon, which is the full moon closest to the autumn equinox. It marks the time when corn, a staple crop, was historically ready for harvest in North America. While full moons often have poetic names, the Harvest Moon is a more specific concept, and in 2025, that honor falls in October, so the September full moon earns the title Corn Moon, marking the traditional time of corn harvesting in the Northern Hemisphere.

This shift happens roughly every 2-3 years.Native American traditions profoundly influenced this naming. Tribes like the Abenaki called it the Corn Maker Moon, while the Zuni saw it as “the Moon when everything ripens and corn is harvested.” It’s a name rooted deeply in the rhythms of agriculture and gratitude.

Why the Corn Moon matters this year

This year’s Corn Moon is extra special because it coincides with a total lunar eclipse, commonly known as a Blood Moon.

This dramatic event occurs when the Earth passes between the sun and the moon, casting its shadow on the Moon, turning it a deep red or coppery color. The total phase, known as totality, will last for about 82 minutes – one of the longest in recent years.

Timings and visibility

The Corn Moon reaches full illumination around 18:08–18:10 UTC on September 7, 2025, which corresponds to roughly 2:10 p.m. EDT. Although full at this moment, the moon remains below the horizon, making moonrise at dusk the best time to observe it.

Where the eclipse (blood moon) will be visible

A dramatic twist accompanies this Corn Moon: a total lunar eclipse. Regions that will see the full Blood Moon effect include:Asia, Australia, Africa, and much of Europe, where totality will be fully visible. For those in North and South America, including India’s neighbors, the moon will have set or not yet risen when the eclipse peaks, so it will be missed directly, but can still be watched via livestreams.
