Witches' meetings, also known as Sabbats, are gatherings of witches and other practitioners of magic. They are usually held at night and involve rituals, spells, and other magical activities. Sabbats are traditionally held eight times a year, on the solstices and equinoxes, as well as four cross-quarter days. These meetings are an important part of the practice of witchcraft and provide a space for witches to come together and share their knowledge and experiences.
