The Sabbats are the witches’ holidays. The word is used for special holidays and feast days celebrated by many Pagans and especially Wiccans and traditional witches. Depending on tradition, there are usually 4 or 8 Sabbats in the year following the pattern of the Wheel of the Year.
Some groups celebrate the four Celtic fire festivals as Sabbats. These are: Imbolc, Beltane, Lughnassadh and Samhain.
Others celebrate the equinoxes and solstices as Sabbats as well. These are: Ostara, Litha, Mabon and Yule
Most groups today celebrate all 8 festivals in one form or another.
These Sabbats may be known by various names.
