The second equinox: light and dark level again, this time tipping toward night. The main harvest is in or coming in, orchards are heavy, and the year takes on a settled, generous quality before the cold.

When is Mabon?

In 2026, Mabon falls on 23 September 2026 in the northern hemisphere. Its date is computed from the sun’s position, so it shifts by a day either way from year to year.

Historical context

Astronomy The September equinox is the sun’s southward crossing of the celestial equator, falling on 21–24 September. After it, nights are longer than days in the northern hemisphere until March.

Historical Britain and Ireland have a well-documented harvest home tradition — the celebration held when the last of the corn was in, with a supper for the workers. Crucially, it was tied to the actual completion of the harvest, which varies with weather and region, not to a fixed astronomical date.

Modern practice The name Mabon is the most clearly modern on the wheel. It was applied to the autumn equinox in the 1970s, borrowing the name of a figure from medieval Welsh literature — Mabon ap Modron, who appears in the Mabinogion — who has no recorded connection to the equinox.

Modern observance

Modern practice Modern practice treats Mabon as a festival of gratitude and of balance in the other direction: a shared meal, apples, and a deliberate look at what is being carried into the dark half of the year.
