What Is Mabon? The Autumn Equinox and Its Pagan Traditions
Share
Mabon (usually pronounced “MAY-bon”, though you’ll hear “MAB-on” too) is the modern Pagan name for the autumn equinox, the point in September when day and night are roughly equal in length. In 2026 it falls on Wednesday 23 September at 1:06am BST. It’s the second of the three harvest festivals on the Wheel of the Year, sitting between Lammas in early August and Samhain at the end of October.
What Actually Happens at the Equinox?
The equinox is an astronomical event, not a matter of belief. Twice a year the Sun sits directly above the equator and both hemispheres get about the same amount of daylight. After the September equinox, the days keep shortening until the winter solstice in December.
“Equal day and night” is also a slight simplification. Because the atmosphere bends sunlight, the day is a little longer than 12 hours on the equinox itself, and the true 12-and-12 split arrives a few days later.
Where Does the Name Come From?
Nobody celebrated a festival called Mabon in ancient times. The name was put forward in the 1970s by Aidan Kelly, an American Pagan writer, who borrowed it from Mabon ap Modron, a figure in medieval Welsh tales. In the story of Culhwch and Olwen, Mabon is taken from his mother when he’s only three nights old and held captive until he’s found and freed.
The link between that story and the equinox is a modern one, and not everyone uses the name. Some Pagans just say “the autumn equinox”, and in modern Druidry it’s called Alban Elfed, often translated as “the light of the water”.
Older Harvest Traditions
The name is recent, but marking the harvest at this time of year is not. Late September has been about gathering in crops in Britain for centuries, and a few customs are still around:
✅ Harvest home, the supper held when the last of the crop was in
✅ Corn dollies, woven from the final sheaf of wheat and kept until the following spring
✅ The church harvest festival, which in its modern form is usually credited to a Cornish vicar, Robert Hawker, in 1843
✅ Michaelmas on 29 September, one of the traditional quarter days
✅ The Harvest Moon, the full moon closest to the equinox
There’s also a bit of folklore that says you shouldn’t pick blackberries after Michaelmas, because the devil spat on them. Whether or not you believe that, the berries do tend to go watery and mouldy by then.
What Does Mabon Mean to Pagans Today?
The main themes are balance, gratitude and preparation. Light and dark are evenly matched for a moment, and the harvest is in, so it’s a natural point to look back at what the year has given you before the dark half begins. Some practitioners also link it to the Greek myth of Demeter and Persephone, whose story explains the change of seasons.
How Is Mabon Celebrated?
✅ Cooking a harvest meal with apples, root vegetables, fresh bread and seasonal fruit
✅ Decorating a table or altar with acorns, pine cones, leaves and gourds
✅ Going for a walk in the woods or foraging, and picking blackberries while you still can
✅ Writing down what you’re grateful for from the past year
✅ Lighting a candle or burning incense to mark the change of season
✅ Having a proper clear-out of the house before winter sets in
None of it needs to be formal. Plenty of people just cook a nice meal and stay in on the night.
Simple Ways to Mark Mabon at Home
✅ Incense in warm, woody or spiced scents, which suit the time of year
