Mabon, or Autumnal Equinox is being celebrated soon. The Wiccan calendar contains 13 full moons (Esbats) and 8 Sabbats, or days of power, making 21 Wiccan ritual occasions. The Esbats are for celebrating the Goddess. The Sabbats mark the sun's yearly cycle and tell the story of The Wheel of the Year. On this day, the length of night time is equal to the length of daytime.
