A ritual is a formal, patterned rite performed on an occasion: a sacrament, an initiation, a calendrical observance, a rite of passage, a consecration. This category gathers the set rites of religious and esoteric practice, recording for each what the rite consists of, the tradition that performs it, and what it is held to accomplish.
Rites tend to be prescribed and repeatable, done in a set way, at set times or on set occasions, and much of a tradition's life is carried in them: birth, initiation, marriage and death are marked by rite in nearly every tradition, as are the turning-points of the year.
