What is Mabon?
Mabon is the festival of the autumn equinox, around 22 or 23 September in the northern hemisphere. Day and night are almost equal, and then the night takes over. In the wheel of the year, it is the second harvest festival (after Lughnasadh) and the last before Samhain. Its theme is gratitude for what has been harvested, and balance before entering the dark season. See solstices and equinoxes for astronomical details.
Where does the name “Mabon” come from?
The name is recent. In the English-speaking world, it is credited to Aidan Kelly, an American neopagan author who is said to have proposed it in the 1970s (around 1970 or 1974, depending on the sources) to name the autumn equinox, alongside Litha and Ostara. The magazine Green Egg then spread it. Gerald Gardner and Doreen Valiente, for their part, did not use it.
Kelly chose Mabon ap Modron, a Welsh figure from the tale Culhwch ac Olwen (found in the Mabinogion collection): Mabon, “son of Modron”, is taken from his mother at the age of three nights and freed from his prison by the men of King Arthur, to help hunt a great boar. His name means “son” or “young boy” (more literally “great son”), and it is linked to an older god, Maponos, a god of youth attested in Roman Britain and in Gaul, whom the Romans equated with Apollo. But nothing in the ancient texts links Mabon to the autumn equinox: the choice is symbolic (the hero who disappears and is found again, like the light that fades and will return).
Ancient harvest festivals
What does exist are harvest and autumn festivals in many cultures. In Britain and Ireland, the Harvest Home celebrated the end of the harvest. The Church set Michaelmas, Saint Michael's Day, on 29 September, which was a day for accounts and rents. The Chinese Mid-Autumn Festival follows the lunar calendar and often falls between September and early October. Grape harvests in the south of France have their own rhythm of festivities. None of these festivals was recorded in ancient texts as “Mabon”.
The harvest moon, the full moon closest to the equinox, is also a seasonal landmark: see our page on the harvest moon.
Mabon in the modern wheel
In the Wiccan narrative, the God declines and the Goddess takes the figure of the Nurturing Mother, who offers the fruits of the earth. This is a modern story. Contemporary Druids use Alban Elfed instead. Mabon is associated with the apple, the grape cluster, the nut, the squash, the cornucopia, the scales, and shades of red, orange and brown (see the cornucopia). As for stones, books cite for example citrine, amber and red jasper, with no official list.

The equinox, in astronomy
At the September equinox, the Sun crosses the celestial equator heading south. Almost everywhere on Earth, it rises roughly due east and sets roughly due west, and the length of the day is close to twelve hours. After this date, the northern hemisphere receives less and less light: the days become shorter than the nights until the March equinox. The equinox is not a whole day but a precise instant, calculated to the minute (23 September at around 12:05 a.m. Universal Time in 2026). The “day” on which the equinox is said to fall therefore depends on the time zone.
Autumn precautions
If you pick fruit, nuts or leaves in the wild, do not eat anything you cannot identify with certainty: wild mushrooms in particular can be deadly, and only pharmacists or mycologists can identify them for you. Nuts and hazelnuts are common allergens. Hot drinks and alcohol are not necessary: a hot apple juice is enough. For candle safety, see fire safety and rituals.
In the southern hemisphere
There, the September equinox heralds spring. Many practitioners therefore celebrate Mabon at the March equinox, and Ostara in September. Others keep the northern dates; both practices exist. Details of the gesture are in the simple Mabon ritual.
Frequently asked questions
When is Mabon in 2026?
The September equinox in 2026 falls on 23 September, at around 12:05 a.m. Universal Time, or about 2:05 a.m. in Paris (summer time). The date varies between 22 and 23 September from year to year.
Is Mabon an ancient Celtic festival?
No: the name was proposed in the 1970s. The character of Mabon comes from medieval Welsh folklore, but he is not linked to any equinox festival in the texts.
What does Mabon mean?
In Welsh, mab means “son” or “boy”. Mabon ap Modron means “Mabon, son of Modron”.
Is Mabon the same festival as Michaelmas?
No. Michaelmas is a Christian feast on 29 September, close to the equinox, which once marked the end of the farming year. There may have been cross-influences, but these are not proven.
What is the difference between Mabon and the Chinese Mid-Autumn Festival?
The Mid-Autumn Festival follows the Chinese lunar calendar (full moon of the eighth month); Mabon follows the solar equinox. Both celebrate the harvest, at times that are close but not always identical.
