The Wheel of the Year is an annual cycle of seasonal festivals in wicca. It consists primarily of eight festivals based around the solstices and equinoxes, known as the quarter days, and the midpoints between, known as the cross quarter days.
Within wicca, many festivals are celebrated. They can vary considerably in name and date among specific traditions, however the eight festivals of the Wheel comprise the most adhered and important annual celebrations. They are a unifying feature of modern wicca. The Wheel has been important to many people, both ancient and modern, and its festivals are based to varying degrees on folk tradition.
