From "sabbath," or "Saturday." In Wiccan terminology, one of eight important holidays marking turning points in the year, based on ancient pagan solar calendars. (The "Sabbath" comes to modern Neopaganism through European witchcraft folklore.) The eight Sabbats together are known as the "Wheel of the year," and are: Samhain, Yule, Imbolc, Ostara, Beltane, Litha, Lughnasadh & Mabon.
