In Wicca the cycle of the seasons is celebrated during eight sabbats called The Wheel of the Year. The seasonal cycle is imagined to follow the relationship between the Horned God and the Goddess. The Horned God is born in winter, impregnates the Goddess and then dies during the autumn and winter months and is then reborn by the Goddess at Yule. The different relationships throughout the year are sometimes distinguished by splitting the god into aspects, the Oak King and the Holly King. The relationships between the Goddess and the Horned God are mirrored by Wiccans in seasonal rituals. There is some variation between Wiccan groups as to which sabbat corresponds to which part of the cycle. Some Wiccans regard the Horned God as dying at Lammas, August 1; also known as Lughnasadh, which is the first harvest sabbat. Others may see him dying at Mabon, the autumn equinox, or the second harvest festival. Still other Wiccans conceive of the Horned God dying on October 31, which Wiccans call Samhain, the ritual of which is focused on death. He is then reborn on Winter Solstice, December 21.
