I can feel autumn. The subtle changes are speaking to something deep inside me. It lets me know the summer growing season is almost over. I bet you can feel it, too.
The amount of daylight is probably the trigger. Since the Summer Solstice on June 21st, the length of daylight has decreased each day. The nights have grown longer. We can sense this just like plants and animals.
Traditionally among many northern hemisphere indigenous peoples, the days around what we now call, August 1st, was the signal that summer was coming to or at an end. How did the ancestors know when was “August 1st”?. Probably by the alignment of the stars in the sky. Or the timing of the Perseids meteor showers. The Perseids happen every year around August 12th
It is 89 days and 20 hours from the autumnal equinox to the winter solstice.
