In this episode of Stuff You Should Know, Josh Clark and Chuck Bryant explore Mabon, a modern pagan festival celebrating the autumnal equinox. Despite its recent origins—coined only 55 years ago by Aidan Kelly—Mabon has become a fixture in contemporary pagan practice. The hosts explain how Kelly created the name by drawing from Welsh mythology rather than ancient Celtic or Druidic traditions, which notably did not celebrate this particular astronomical event.
The episode examines the spiritual significance of the autumnal equinox as a moment of balance between light and darkness, and how Mabon fits into the pagan Wheel of the Year alongside other harvest festivals. Clark and Bryant also discuss practical ways to celebrate the season, from reflecting on the past year with gratitude to embracing fall activities like walks among changing leaves. Whether approached from a spiritual perspective or simply as a seasonal observance, Mabon offers opportunities for anyone to mark the transition from summer to autumn.

The term "Mabon" was coined only about 55 years ago by Aidan Kelly while assembling the modern pagan Wheel of the Year. Despite its contemporary popularity, the autumnal equinox was not celebrated by original pagans like the Celts or Druids—even Stonehenge hosts no special events at this time. Kelly drew inspiration from Greek mythology, noting that Demeter, celebrated around the autumnal equinox, shares a mythic element with Mabon: both involve a young figure rescued from the underworld.
The name "Mabon" originates from Welsh mythology, where Mabon appears as a god and hero in the medieval compilation, the Mabinogion, featuring tales of King Arthur. When Kelly looked for appropriate Gaelic or Germanic names for the autumnal equinox and found none with historical precedent, he settled on "Mabon" as a reference, borrowing from Welsh mythology to provide a mythological anchor for the festival.
Josh Clark explains that during the autumnal equinox, day and night are each nearly 12 hours long, creating a moment of balance between light and darkness. This celestial event is celebrated in Mabon, where practitioners honor the equilibrium between opposing forces. Chuck Bryant suggests that observers might meditate on balance in their own lives, considering adjustments that could restore or enhance it. Unlike the spring equinox, which is associated with renewal and growth, the autumnal equinox encourages release and preparation for reduced activity, with people reflecting on the year's harvests and letting go of what no longer serves them.
Within the Pagan calendar's Wheel of the Year, Mabon is one of three major harvest festivals, following Lunasa in early August and preceding Samhain in October. The Wheel features eight sabbats, including classic festivals with ancient Celtic roots like Samhain, Lunasa, Beltane, and Imbolc. Notably, Mabon is the only sabbat that was explicitly created by modern neopagans rather than derived from ancient traditions. While early Celts didn't recognize the autumnal equinox, various other cultures have long celebrated this astronomical event. A striking example is the Pyramid of Kukulkan at Chichen Itza, where the equinox creates the illusion of a serpent undulating down the steps through shadow and light.
Mabon offers opportunities for celebration that can be meaningful for anyone. Reflecting on the past year with gratitude, similar to Thanksgiving, helps mark the transition from summer to fall. The season also invites contemplation of equilibrium in your own life, identifying areas where greater balance might be needed. Decorating with harvest-inspired items like cornucopias, gourds, autumn leaves, and pumpkins honors the season's abundance. Non-pagans can celebrate through outdoor activities like experiencing the changing leaves on walks or visiting corn mazes, which support local farms. Simply enjoying fall weather and seasonal festivities captures the essence of Mabon without requiring any religious or spiritual commitment.
1-Page Summary
The term "Mabon" is a recent addition, coined only about 55 years ago by Aidan Kelly in the 1960s and 70s while assembling the modern pagan Wheel of the Year. Kelly sought to find names for each seasonal festival, aiming to offer structure for modern pagan observances.
Despite its contemporary popularity, the autumnal equinox was not an event celebrated by the original pagans such as the Celts or Druids. There is no ancient Celtic or Druidic tradition correlating with "Mabon" as a festival. For example, if one visits Stonehenge during the autumnal equinox, no special event or ritual takes place to mark the occasion—indicating the lack of ancient recognition for this date. Thus, Mabon has no historic link to original druidic or Celtic celebrations of the equinox.
Aidan Kelly, in his research, discovered that Greek mythology recognized harvest-related deities such as Demeter, who is traditionally celebrated around the autumnal equinox. Noting that Demeter shares a mythic element with Mabon—both involving a young figure rescued from the underworld—Kelly saw this parallel as sufficient thematic justification to name the autumnal equinox festival "Mabon."

Origins and History of Mabon as a Pagan Harvest Festival
The autumnal equinox holds significant spiritual meaning as a moment of balance between light and darkness. Josh Clark explains that during the autumnal equinox, as well as the vernal or spring equinox, day and night are each nearly 12 hours long. This celestial event is celebrated in various traditions, including Mabon, where practitioners honor the equilibrium between opposing forces. Mabon observers focus on this equal division of light and darkness as a symbol of spiritual and natural balance, finding meaning in the alignment of these cosmic energies.
The balance of the equinox inspires practitioners to reflect on their own lives. Chuck Bryant suggests that those observing Mabon might meditate on balance, considering adjustments that could restore or enhance it within themselves. The autumnal equinox, unli ...
Significance of Balance and Spiritual Meaning During Autumnal Equinox
Within the Pagan calendar, known as the Wheel of the Year, Mabon is recognized as one of three major harvest festivals. The cycle begins with Lunasa in early August, marking the first harvest festival and the start of the reaping season. Following this, Mabon, celebrated in late September, is considered the primary or “money” harvest festival—when the majority of crops are ready to be picked. The third and final harvest festival is Samhain in October, which is also closely tied to Halloween.
The Wheel of the Year features eight sabbats, encompassing key turning points in the solar calendar. Classic sabbats with ancient Celtic roots include Samhain, Lunasa, Beltane, and Imbolc. These festivals have authentic historical traditions among the Celts and Druids. Notably, the autumnal equinox, celebrated by modern pagans as Mabon, was not actually observed as a festival by ancient Druids or Celts. Instead, modern neopagans, Druids, and Wiccans explicitly added Mabon to the cycle to mark the significance of the autumnal equinox and to structure the year evenly between the solstices and equinoxes.
Mabon in the Wheel of the Year and Other Harvest Festivals
Mabon, the autumnal equinox, offers opportunities for celebration and reflection that can be meaningful for anyone, regardless of spiritual background. Both pagans and non-pagans can find joy in embracing the spirit of the season through gratitude, decoration, and outdoor activities.
Reflecting on the past year is a fundamental part of Mabon observance. Taking time to consider what you are thankful for, just as during Thanksgiving, can bring a sense of closure and contentment. Expressing gratitude, acknowledging your achievements, and recognizing growth help to mark the transition from summer to fall.
Mabon marks a point of balance in the year. Use this time to contemplate the equilibrium in your own life. Identify areas where you may need greater balance or harmony, setting intentions to cultivate it in the coming months.
The cornucopia, or horn of plenty, is a symbolic fall decoration rooted in ancient Greece. It serves as an iconic centerpiece for fall and the autumnal equinox. Having a cornucopia in your home is a beautiful way to celebrate the abundance and harvest of the season, connecting with an ancient custom that still holds significance today.
Decorating your home with harvest-inspired items such as gourds, autumn leaves, pumpkins, and sheaves of wheat further honors the season. These decorations not only enhance the beauty of your surroundings but also create an atmosphere of gratitude and abundance.
