Autumnal Equinox

The autumnal equinox, or Mabon, is the Wiccan's Thanksgiving. 
Also called Harvest Home, this holiday is a ritual of thanksgiving for the fruits of the Earth and a recognition of the need to share them to secure the blessings of the Goddess and God during the winter months.
Among the sabbats, it is the second of the three harvest festivals, preceded by Lammas and followed by Samhain.
