provides an easy to understand explanation.
Many people are familiar with the summer and winter solstice celebrations around the world but let us not leave out the Equinoxes, that while a pivotal part of the astronomical year, are often overlooked
Ancient people understood and celebrated the importance of the equinoxes marking the seasonal changes from summer to fall – the time for harvesting and preparing for winter and from winter to spring – the time for preparing to plant crops. The equinoxes mark the rhythm of sowing and reaping to sustain life and are certainly worthy of celebration. Here are nine Equinox celebrations across the world that you may not have known about.
In the UK an ancient celebration was given a new name. Ancient Celts marked the cyclical behavior of the Sun with a series of celebrations called Sabbats. In the 1970s two new Sabbats were added to coincide with the equinoxes. Mabon
was the name given to the autumnal equinox when pagans give thanks for the summer months that have provided the fruits of the harvest season. Often times altars are built that contain food especially apples as they are harvested in September.
Some celebrating Mabon gather at Stonehenge to watch the sunrise, give thanks for the harvest and look forward to the winter solstice.
The Snake of Sunlight
– In Mexico at Chichen Itza
at the precise moment of the equinox, a shadow forms on the main stairs of the ancient Mayan pyramid, El Castillo. The shadow looks like a snake slithering down the stairs of the pyramid. People from all over the globe gather to watch.
- In Japan, there’s a Buddhist celebration called Higan
, , which is celebrated during the September and March equinoxes. This is because at the equinox, the sun sets due west – which is where the Japanese Buddhists believe the land of the afterlife is located.
Both equinoxes have been national holidays since the Meiji period. It is a time to remember the dead by visiting, cleaning, and decorating their graves. Higan is also a time of meditation and to visit living relatives.
– In China and Viet Nam the Mid-Autumn Festival or Moon Festival is typically celebrated on the full moon closest to the September equinox. This year, that will actually be on September 20 (HST) and September 21 (GMT).
The Moon Festival celebrates the summer harvest – like so many other equinox celebrations on this list. People celebrate by giving mooncakes to friends and family. Mooncakes are a delicious pastry with lotus, sesame seeds, duck egg, or dried fruit on the inside. The Moon Festival is also a great time to spend time moon-gazing!
In Korea also celebrates the Moon festival by giving Moon pies.
- Hindu people in India celebrate Navratri, a festival that lasts several days in the months of September and October. The festival honors the divine feminine Devi (Durga).
Neris River Autumn Equinox Celebration
- In Vilnius, Lithuania, people light candles after sunset during the autumn equinox celebration at the Neris River waterfront.
Feast of Greener
- In Poland, people celebrate the Feast of Greener by getting foods and bouquets blessed by a priest and using them for medicine.
