The Sabbats

Sabbats are seasonal festivals which mark key points in the natural year, because paganism is a Nature-Oriented Religion and Craft, witches celebrate and get in tune with the natural aspects of the seasons, either their agricultural, pastoral, botanical, solar, lunar, wildlife, planetary, psychic, the tides and cycles. Bealtaine, Lughnasadh, Samhain and Imbolg are the "greater Sabbats", sometimes called "Fire Festivals", and the Equinoxes and Solstices are the "Lesser Sabbats", not because they are less important in any way, but because they mark the turning of the seasons.
