Esbats, derived from the French esbattre, meaning “to frolic,” are gatherings or solitary rituals held every month on the night of that month’s full moon, to worship the goddess as represented by the moon. Some groups and solitaries may hold their esbats on the night of the new moon, however. It is also the correct time to hold an esbat, and some motivated groups or persons may hold rituals on both nights. Esbats may also be known as lunar rituals.
While sabbats are strictly days of celebration, esbats are known as “working” rituals. This is usually the time set aside for a coven, groups or solitaries to perform magick, such as casting spells for the success of a new endeavor, healing rituals, etc.
