The Fall Equinox: Meaning, Rituals, and Celebration Ideas

As the days grow shorter, the Fall Equinox arrives between September 21 and 24 and is the first official day of Fall. Primarily, the autumn equinox is primarily an astronomical moment when there is an exact balance in the light between day and night at the equator.

But the equinox also invites us to slow down, reflect on our own harvest, and prepare for quieter months ahead. I personally love it for the food, the cooler air, and the opportunity to work with Persephone as she rises into full power in her other domain.

Let’s explore the spiritual meaning of the Autumn Equinox, its core themes, and how to work with its energy through rituals, symbols, and simple seasonal practices.

When Is the First Day of Fall?

The first day of Fall changes each year, but begins with the Fall Equinox. Here’s a look at when the Autumnal Equinoxes occur in 2025 and in coming years.

What Is the Fall Equinox?

The Fall Equinox falls between September 21 and 24 and is one of two times each year when day and night are equal in length. The other time this occurs is on the vernal or Spring Equinox which is in March.

Astronomically, it’s the moment the sun crosses the celestial equator, signaling the start of autumn in the Northern Hemisphere. It is also the time when the Sun’s path, the ecliptic, and the celestial equator meet.

Cultures across the world have recognized the Autumn Equinox as a moment of balance and change for centuries. Ancient peoples built monuments aligned with the equinox sun, including Chichén Itzá.

And, in Greek mythology, this turning of the seasons is echoed in the story of Persephone’s descent into the Underworld. While the Greeks didn’t celebrate the equinox explicitly, this was the time of the Eleusinian Mysteries, the secretive initiation rites into the Demeter and Persephone’s mystery religion.

The equinox wasn’t a major festival in Celtic traditions, but modern Pagan and Wiccan paths now mark it as Mabon on the Wheel of the Year, a time of harvest, reflection, and preparation for the darker half of the year.

What’s the Difference Between a Solstice and an Equinox?

The key difference between a solstice and an equinox lies in how the sun’s position affects day and night. An equinox occurs twice a year, around March 20 and September 22, when the sun is directly above the Equator.

The equinox creates roughly equal lengths of daylight and darkness across the globe. The Spring (vernal) Equinox marks the transition into longer days, while the Fall (autumnal) Equinox signals the shift toward shorter ones.

There are also two solstices each year. These occurs around December 21 and June 21 when the sun’s path is the farthest it can be from the Equator. The Summer Solstice (known as Litha to Wiccans and some pagans) brings the longest day and shortest night of the year. The Winter Solstice (also known as Yule) brings the shortest day and longest night.

To summarize, in the Northern Hemisphere:

• Spring Equinox (March 19-21): The Sun above the Equator. Day and night are equal in length. This is the first day of Spring.
• Summer Solstice (June 20-22): The Sun is over the Tropic of Cancer and at the farthest Southern point from Equator. It is the longest day of the year and the first day of Summer.
• Fall Equinox (September 21-24): The Sun above the Equator. Day and night are equal in length. This is the first day of Autumn.
• Winter Solstice (December 20-23): The Sun is over the Tropic of Capricorn and at the farthest Northern point from Equator. It is the longest day of the year and the first day of Winter.

Spiritual Meaning of the Autumn Equinox

The Autumn Equinox marks a turning point in the year. Day and night are about equal in length, and from here, the nights begin to grow longer. It is a time of reflection, recalibration, and preparation for the season ahead. The Full Moon closest to the equinox is known as the Harvest Moon, adding lunar energy to the season’s focus on gratitude and abundance.

Some themes to consider journaling or doing rituals for during this time include the following. Here’s a full ritual guide to the equinox.

Balance

With equal hours of light and dark, the equinox is nature’s reminder to check in with yourself. Are you spending too much energy in one area of life and neglecting another? Are your routines supporting your well-being? Think of this as a seasonal reset where you get to realign your time, energy, and attention.

Balance rituals might include: Making a two-column intention list of what to release vs. embrace, and lighting two candles (one dark, one light) to meditate on internal harmony and balance.

Harvest

This is the second of the three harvest festivals on the Wheel of the Year, and it’s about more than just apples and pumpkins. Spiritually, the Autumn Equinox invites you to recognize what you’ve cultivated in your life. Consider projects you’ve completed, relationships you’ve deepened, and your own personal growth.

Harvest rituals might include: Crafting a gratitude jar or preparing a meal with seasonal foods while reflecting on what you’ve accomplished.

Release

Just as trees begin to shed their leaves, we’re invited to consider what we might let go of. That could mean outdated habits, beliefs that no longer serve you, or emotional weight you’re ready to set down. Even small shifts like setting boundaries can create space for something new.

Release rituals might include: Burning a written list of what you’re releasing, clearing out a physical space, or doing a cord cutting.

Gratitude

This is a season of giving thanks. Gratitude at the equinox isn’t just about what’s gone well. It’s about appreciating the full spectrum of your experience. The lessons, the people, the challenges you’ve overcome. Taking stock of what you’re thankful for can help you move into the darker months with a greater sense of perspective.

Gratitude rituals might include: Keeping a seasonal gratitude journal, offering food or flowers to your altar, ancestors, or community, or hosting a dinner where each person shares something they’re thankful for.

Descent

As the sun’s path lowers in the sky and the days grow shorter, we enter a quieter, more introspective part of the year. The equinox can be a symbolic doorway. Use it as a time to slow down, turn inward, and reconnect with what grounds you.

Descent rituals might include: Creating a shadow altar or one dedicated to the Underworld gods, pulling tarot cards to connect with your subconscious, or taking a quiet evening walk at dusk to honor the shift from light to dark.

How Cultures Around the World Celebrate the Fall Equinox

Across the globe, the autumn equinox has inspired rituals, festivals, and cultural traditions that honor seasonal change. While the timing and meanings vary, many of these observances reflect themes of balance, harvest, and transition.

• Mexico: Every equinox, visitors gather at the ancient temple of Kukulkan in Chichén Itzá to watch the serpent-like shadow descend the staircase.
• Lithuania: Miķeļi is a Baltic harvest festival celebrated near the autumn equinox. Traditionally, it included feasting, offerings of grain and bread, and rituals to honor the fertility of the land and give thanks for a successful harvest. Folk songs, symbolic sheaf decorations, and divination games were often part of the festivities.
• Japan: Shūbun no Hi is a national holiday in Japan that marks the transition to autumn and honors ancestral spirits. Families visit graves, clean ancestral tombstones, and offer flowers and seasonal foods. It’s also a time for reflection, balance, and reconnecting with nature and loved ones.
• Korea: Chuseok is a major three-day harvest festival in Korea, celebrated near the autumn equinox. Families return to ancestral homes, perform memorial rites, share traditional foods like rice cakes, and wear traditional clothing. The holiday emphasizes gratitude, family unity, and honoring ancestors.
• China, Taiwan, and Hong Kong: The Mid-Autumn Festival is held on the 15th day of the 8th lunar month, often aligning with the equinox. It honors the full moon and themes of reunion, abundance, and harmony. Celebrations include eating mooncakes, lighting lanterns, sharing stories of the moon goddess Chang’e, and moon gazing with family.
• Judaism: Rosh Hashanah, the Jewish New Year , is held 163 days after Passover, often on the New Moon closest to the Autumnal Equinox. The holiday marks a time of spiritual reflection, prayer, and renewal. Traditions include blowing a shofar (ram’s horn), eating symbolic foods like apples dipped in honey, and setting intentions for the year ahead.

How Is the Fall Equinox Different from Mabon?

The terms are often used interchangeably, but they’re not exactly the same. The Fall Equinox is the astronomical event. The time when the sun aligns with the equator and day and night are equal.

Mabon is a modern Pagan sabbat named in the 20th century, drawing inspiration from other seasonal festivals. While the equinox is universal, Mabon is specifically rooted in the Wheel of the Year. To learn more about Mabon, check out our guide!
