Wiccans observe both esbats and sabbats. Esbats are rituals concerning the phases of the moon. Sabbats are similar to what you might call a holiday and are displayed on the wheel of the year. These rituals often involve the gathering of a coven (a group of witches), a feast, and dance. Ritual attire varies by the beliefs of the coven. These celebrations are generally focused on the Goddess, God, and the moon. How these are celebrated can differ depending on personal beliefs or coven practices.
