Some gleanings from Wikipedia:

The traditional harvest festival in the United Kingdom was celebrated on the Sunday of the full moon closest to the September equinox.

The September equinox marks the first day of Mehr or Libra in the Persian calendar. It is one of the Iranian festivals called Jashne Mihragan, or the festival of sharing or love in Zoroastrianism.

The September equinox was “New Year’s Day” in the French Republican Calendar, which was in use from 1793 to 1805. The French First Republic was proclaimed and the French monarchy was abolished on September 21, 1792, making the following day (the equinox day that year) the first day of the “Republican Era” in France. The start of every year was to be determined by astronomical calculation, (that is: following the real Sun and not the mean Sun as all other calendars).

You may see some objects hover slightly off the ground every so often today. Don’t be alarmed, this is normal. Just leave them alone and let them do their thing.
