What is Mabon?
Mabon is a Wiccan and modern Pagan sabbat celebrating the autumn equinox, the astronomical moment when day and night stand in equal length. It is the second of three harvest festivals on the Wheel of the Year, falling between Lughnasadh (Lammas) and Samhain. Observed around September 22 in the Northern Hemisphere (March 20–21 in the Southern Hemisphere), Mabon marks the threshold between summer abundance and winter scarcity, a time of gratitude for the harvest and preparation for the coming darkness.
Unlike the ancient Celtic fire festivals—Imbolc, Beltane, Lughnasadh, and Samhain—there is no solid evidence that the Celts formally celebrated the fall equinox as a distinct holy day. The name “Mabon” itself is not ancient. In 1974, American witch Aidan Kelly claims to have given the holiday its name while developing a Wiccan liturgical calendar. Most of the other sabbats already had a Celtic name; the mundane name “autumn equinox” offended his sensibilities, so he drew from Welsh mythology. He chose the name from Welsh mythology—Mabon ap Modron, which means “Son of the Mother”, a divine youth whose story involves abduction, imprisonment, and eventual liberation—themes Kelly saw as parallel to the Greek myth of Persephone.
Origins & Lineage
Aidan A. Kelly (born October 22, 1940) is an American academic, poet and influential figure in the Neopagan religion of Wicca. Having developed his own branch of the faith, the New Reformed Orthodox Order of the Golden Dawn, during the 1960s, Kelly sought to systematize the emerging Wiccan calendar. The name originates with a Pagan-Craft Calendar which was published in 1970 by Aidan Kelly. Kelly renamed the holiday and submitted his new calendar to be published in The Green Egg, one of the first pagan magazines, and the name took root in the wider community.
Mabon derives from the Mabinogion (pronounced Mabin-OGion), a collection of 14th-century stories written in Middle Welsh. The Mabinogion was compiled from texts found in two late-medieval manuscripts. Mabon is the son who was stolen away from his mother and which Culhwch was tasked to find to win the hand of the beautiful Olwen. With the aid of King Arthur he did indeed free Mabon from his imprisonment, as told in the Tale of Culhwch and Olwen. Mabon, the god, has no connection to the autumn equinox. His story doesn’t even take place in the fall.
While the name is recent, equinox veneration is not. The ancient Mayans designed Chichen Itzá to mark the equinox sun, while Neolithic and Bronze Age peoples built sites like Carin T in Ireland and Mnajdra in Malta that align with the sunrise on this day. The Venerable Bede, writing in the early 700s, notes that September was the Anglo-Saxon holy month (Haligmonað) when the harvest was celebrated. In the Viking Age, the closest parallel to Mabon would be haustblót, the autumn blót. This was a sacrificial feast to honour the gods, ancestors, and landvættir (spirits of the land) as the harvest came in.
How It’s Practiced
Mabon observances center on balance, thanksgiving, and release. Practitioners honor the equal measure of light and dark by creating altars adorned with autumn symbols: apples, gourds, wheat sheaves, acorns, wine, grapes, and colored leaves. Pagans might pick apples. Apples are a common symbol of the second harvest. They may use the apples in an apple harvest ritual that thanks the gods for the bountiful harvest.
Rituals often invoke themes of equilibrium and preparation. Others might perform a ritual to restore balance and harmony to their lives, as this holiday celebrates a day with equal light and day. Some practitioners incorporate mythic re-enactments or meditations on descent narratives—Persephone entering the underworld, Mabon freed from captivity—to acknowledge the cycle of loss and return.
Community gatherings may include feasting with seasonal foods (root vegetables, bread, cider, mead), outdoor processions, gratitude circles, and offerings to land spirits. Solo practitioners often engage in journaling exercises focused on what they wish to release before winter’s introspection and what they hope to preserve from the harvest of the year’s efforts.
Mabon Today
Mabon has gained visibility in the decades since its naming. Contemporary Wiccans, eclectic Pagans, and Earth-honoring practitioners include it in their liturgical cycles, often blending Kelly’s framework with personal or reconstructionist elements. Mabon-themed workshops, seasonal retreats, and public rituals are offered by Pagan centers, permaculture farms, and nature sanctuaries, particularly in North America, the United Kingdom, and Australia.
Booksellers and online platforms feature Mabon guidebooks, from Diana Rajchel’s Mabon: Rituals, Recipes & Lore for the Autumn Equinox to broader Wheel of the Year compendiums by Scott Cunningham and Nigel Pennick. Instagram and TikTok communities share altar setups, gratitude practices, and foraged decor, making Mabon accessible to solitary practitioners who may not have access to covens or live circles.
Some Celtic Reconstructionists and Welsh Pagans avoid the term altogether, preferring Welsh names like Alban Elfed (Druidic) or simply “Autumn Equinox,” citing its lack of historical precedent. The debate around the name persists but has not diminished the sabbat’s popularity within eclectic Wiccan and Neopagan communities.
Common Misconceptions
Mabon is not an ancient Celtic festival. The name is ahistorical since the Celts (the source of many of the festival names) did not celebrate equinoxes. It is a 20th-century innovation, created for liturgical symmetry in the Wiccan Wheel of the Year. It does not appear in medieval grimoires, historical pagan calendars, or pre-Christian European sources.
The name is sometimes mispronounced. It is typically rendered as MAY-bon (some say MAH-bon), but there is no single authoritative pronunciation, as the word was retrofitted from a proper noun in Welsh myth.
Mabon is not synonymous with Thanksgiving in the United States or Harvest Home in England, though thematic overlap exists. Those are secular or Christian harvest customs with different origins.
Finally, Mabon is not universally embraced by all Pagans. Some prefer terms rooted in their ancestral or regional traditions; others see the Wheel of the Year as a flexible template rather than dogma.
How to Begin
If you wish to explore Mabon, start with observation. Note the equinox date in your hemisphere. Spend time outdoors noticing the shift in light, the quality of air, the ripening or falling of fruit. Bring an apple or a handful of grain to a natural space and speak words of gratitude aloud or silently.
Read Diana Rajchel’s Mabon: Rituals, Recipes & Lore for the Autumn Equinox for a focused introduction, or Scott Cunningham’s Wicca: A Guide for the Solitary Practitioner for broader context on the Wheel of the Year. Nigel Pennick’s The Pagan Book of Days offers historical texture.
Attend a public Mabon ritual if one is offered in your area—many Unitarian Universalist congregations, Pagan Pride events, and metaphysical shops host open circles. If solitary practice appeals to you, create a simple altar with seasonal objects and light a candle at sunset on the equinox, reflecting on balance in your own life: what to keep, what to release, and what to prepare for the darker months ahead.
