ordinarily staged by a community, centering on and celebrating some unique aspect of that community and its traditions, often marked as a local or national holiday, mela, or eid.

Food (and consequently agriculture) is so vital that many festivals are associated with harvest time.
Religious commemoration and thanksgiving for good harvests are blended in events that take place in autumn such as Halloween in the northern hemisphere and Easter in the southern.
