Also Mabon.
A name for the autumnal equinox, also known as the Second Harvest Festival, Festival of Dionysus, Wine Harvest, Cornucopia, Feast of Avalon, etc. The first Thanksgiving was held on or near this date, and it is from these early harvest festivals that the modern Thanksgiving feasts developed.

At this time of equal day and night, we give thanks for the harvest that will sustain us through the dark winter months. This is the season for gratitude and for giving back to the Earth; for continuing the cycle by giving freely to those less fortunate than we are.
