Quarter Days: The Solstices and Equinoxes

The solstices and equinoxes are the four moments in the solar year when the sun reaches its most extreme positions or its balance points in relation to the Earth’s tilt, and they have been marked by human cultures around the world for as long as we have records of seasonal observance. In the contemporary pagan Wheel of the Year, they are the quarter days, the four solar festivals that alternate with the four cross-quarter days to create the complete eight-festival seasonal cycle. Each carries distinct qualities, mythological associations, and magical potential.

The astronomical basis of these festivals is straightforward. The winter solstice, occurring around December 21 in the Northern Hemisphere, is the moment when the sun reaches its southernmost point in its apparent path, resulting in the shortest day and longest night of the year. The summer solstice, around June 21, is the opposite: the sun at its northernmost point, the longest day and shortest night. The spring equinox, around March 20, and the autumn equinox, around September 22, are the moments when the sun crosses the celestial equator and day and night are approximately equal. From these four astronomical events, all the seasonal festivals of the solar calendar can be derived.

History and origins

Human attention to the solstices and equinoxes is extraordinarily ancient. The passage tomb at Newgrange in County Meath, Ireland, was built around 3200 BCE, more than five thousand years ago, with a roof-box designed to illuminate the chamber at the winter solstice sunrise. Stonehenge in Wiltshire, England, built in phases from around 3000 to 1500 BCE, is aligned to both solstices. The Egyptian temple complex at Karnak was aligned to the winter solstice sunset. These architectural achievements testify to the importance of solar observation in the cultures that built them, though what rituals accompanied these observations is largely a matter of inference.

The specific names used in contemporary paganism for the four solar sabbats have varied histories. Yule is a Germanic word for the winter solstice period, attested in Old Norse and Old English sources. Midsummer is self-explanatory and cross-culturally used. Ostara as a spring festival name derives from the Anglo-Saxon spring goddess mentioned by the Venerable Bede in his work De Temporum Ratione (eighth century CE), though her historical existence and the festivals associated with her are debated by scholars. Mabon as a name for the autumn equinox festival was coined by Aidan Kelly in the 1970s and is not a traditional use of the Welsh name Mabon fab Modron, a mythological figure; it was adopted by the pagan community and has become standard usage within it.

In practice

Each of the four solar festivals has its own spiritual quality, determined both by the astronomical fact of its position in the year and by the mythological associations that have accumulated around it in the traditions of Wicca and contemporary paganism.

Yule, the winter solstice, is the festival of the sun’s return: the longest night has been reached, and from this point the light begins to increase, however imperceptibly. In Wiccan mythology it is the moment of the Horned God’s rebirth; in the broader Norse tradition it was a midwinter celebration of feasting, gift-giving, and light in the darkness. Practices include the burning of the Yule log (traditionally a large piece of wood burned throughout the night and kept as a charm), candlelight, bringing evergreen plants into the home as symbols of enduring life, and staying awake through the longest night to greet the returning sun.

Ostara, the spring equinox, celebrates the balance point at which light overtakes dark and the world is visibly quickening. It is associated with fertility, new beginnings, eggs as symbols of potential life, and the first flowers of the season. The contemporary association of this festival with the hare predates its connection to Wicca; the concept of a hare associated with spring and eggs appears in various forms in northern European folk tradition. Magical workings at Ostara are well suited to planting intentions, beginning new projects, and celebrating the return of color and warmth after winter.

Litha or Midsummer, the summer solstice, marks the peak of the sun’s power and simultaneously the turning point at which the days begin to shorten. It is a festival of fire and light, of the faery world (midsummer was traditionally considered a time of fairy activity in British and Irish folklore), and of the sun standing still, which is what the word solstice means. Bonfires, especially if lit on hilltops, are traditional. Herbs gathered at midsummer were considered especially potent in folk magical traditions.

Mabon, the autumn equinox, is the second balance point, now with dark overtaking light. It is a time of giving thanks for the harvest, of acknowledging what has been gathered and what must be released, and of beginning to turn inward as the year moves toward its dark half. The parallel to the myth of Persephone’s descent is often drawn; this is the moment when the world begins its agreement with winter.

Working with the solar cycle

The quarter days work well for both devotional and magical practice. Their astronomical basis means that each has a specific, verifiable moment of occurrence, which can be used for timing rituals precisely. Their mythological resonance with light and dark, growth and decline, makes them natural frameworks for workings related to illumination, new beginnings, release, and the balancing of opposites. Many practitioners find that the solar festivals, because they are tied to the sun’s actual position, feel different in their quality of light and season than the cross-quarter days, and this sensory reality gives the rituals a grounding that purely mythological observances sometimes lack.

In myth and popular culture

The solstices and equinoxes appear in mythology across an extraordinary range of cultures. The winter solstice birth narrative, in which a solar deity is born at the darkest point of the year to return light to the world, appears in the myths of Mithra, the Roman Sol Invictus, Dionysus, and in the traditions that shaped the timing of Christmas. The summer solstice is associated in Norse tradition with the Midsommar fires, with the fae courts of British and Irish folklore reaching their height of activity, and with the myth of the Oak King giving way to the Holly King as the year turns toward darkness. The spring equinox is the setting for the myth of Persephone’s return from Hades, her emergence from the underworld greeted by the earth’s flowering, which is the oldest recorded account of a seasonal festival in the Greek tradition.

Shakespeare’s A Midsummer Night’s Dream is set during the summer solstice and explicitly invokes the theme of liminal time: the fairy world bleeds into the human, reason fails, and enchantment operates freely. This reflects genuine folk belief about the solstice as a time when the boundaries between worlds thin. Thomas Hardy’s novel The Return of the Native (1878) centers a key dramatic sequence on a midsummer bonfire, depicting it as both community celebration and folk ritual with genuine emotional power. More recently, the film Midsommar (2019) placed a Swedish midsummer ritual community at the center of its horror narrative, drawing directly on solstice bonfire traditions and their ceremonial role in marking the solar year.

In contemporary culture, the solstices and equinoxes are marked by major public gatherings at Stonehenge, where thousands gather each year for dawn on the summer solstice. This gathering has grown from a small pagan revival event in the twentieth century into one of the largest seasonal celebrations in Britain, attracting both genuine practitioners and many visitors who come for the spectacle of the sun aligned with the stones.

Myths and facts

Several persistent misunderstandings about the solstices and equinoxes circulate both in pagan communities and in the broader culture.

• A common belief holds that the equinoxes are days on which day and night are exactly equal to twelve hours each. In practice, due to the refraction of light through the atmosphere and the size of the sun, day is slightly longer than night even on the equinox. True equal day and night occurs a few days before the spring equinox and a few days after the autumn equinox.
• Many people assume that Stonehenge was built specifically to mark the summer solstice sunrise. The site is actually aligned to the winter solstice sunset, and researchers now consider this the more likely primary solar alignment for the monument. The summer solstice gathering at Stonehenge is a modern tradition that reversed the ancient orientation.
• The sabbat name Mabon for the autumn equinox is often presented as an ancient name for the festival. It was coined by the American pagan writer Aidan Kelly in the 1970s and has no documented historical use as a festival name; it was borrowed from a Welsh mythological figure.
• It is widely assumed that all ancient cultures celebrated the same four solar festivals as paganism does today. Ancient observances varied enormously; some cultures emphasized the solstices, others the equinoxes, and many focused on agricultural or lunar cycles that do not align neatly with the modern Wheel of the Year.
• Some practitioners believe the Southern Hemisphere should simply reverse the sabbat calendar, so that the winter solstice festival falls in June. This is one valid approach, but others in the Southern Hemisphere choose to honor both the astronomical event and their own experienced season, creating hybrid approaches specific to their place.
