Autumn Equinox

Fall begins (Northern H.) History

The Observance of the Beginning of Fall, also known as the Autumnal Equinox, is a significant event marking the transition from summer to autumn. As one of the two equinoxes that occur each year, this celestial occurrence signifies when day and night are of equal lengths, an aspect deeply rooted in cultural and religious practices. The equinox is a reminder of the changing seasons and a time to prepare for the cooler months ahead, with its influence spanning various traditions, agricultural activities, and the establishment of astronomical calendars throughout history.

The Autumnal Equinox has a rich history of cultural symbolism and significance for the United Kingdom. With roots tracing back to ancient Celtic beliefs and medieval Christian customs, the event has been celebrated and recognised as a time of harvest and thanksgiving. The equinox bears particular importance in the Druid and Pagan communities of the UK, where the observance is known as Mabon. Mabon serves as an opportunity for individuals to give thanks for the harvest, acknowledge the season's passing, and begin preparations for the winter months.

In the United Kingdom, the Autumnal Equinox typically falls between September 22 and 24, a time when numerous events and celebrations occur throughout the country. In Wiltshire, England, the ancient monument of Stonehenge is a prime location for individuals to witness and celebrate the equinox, as the site is precisely aligned with the equinox sunrises and sunsets. Additionally, harvest festivals are held in various regions, consisting of feasts, music, and gatherings to appreciate the abundance and togetherness that comes with the season's bounty.

• The term 'equinox' is derived from the Latin words aequus (equal) and nox (night), reflecting the astronomical phenomenon where the Sun sits directly above the Earth's equator, causing day and night to be nearly equal in length across the globe.

• The equinox is also celebrated in Druidic tradition as Alban Elfed, or 'The Light of the Water,' a name reflecting the deep importance of the natural world to ancestral British cultures during the shift into autumn.
• Atmospheric refraction causes the Sun to appear higher in the sky than it actually is, which extends the length of the day by several minutes and prevents the daylight and darkness from being a perfectly precise 12-hour split.
• The full moon occurring closest to the autumnal equinox is famously known as the Harvest Moon; historically, its prolonged light enabled farmers to work late into the night to secure their crops before the onset of winter.
• Geomagnetic activity, which fuels the spectacular Northern Lights (aurora borealis), is statistically more likely to occur around the equinoxes than during the summer or winter months.
• The word 'autumn' itself has deep historical roots, evolving from the ancient Etruscan autu—meaning 'the passing of the year'—before becoming the Latin autumnus and eventually entering the English language in the 16th century.
