A festival or gala' is an event, usually and ordinarily staged by a local community, which centers on and celebrates some unique aspect of that community and the Festival.
Among many religions, a feast is a set of celebrations in honour of God or gods. A feast and a festival are historically interchangeable. However, the term "feast" has also entered common secular parlance as a synonym for any large or elaborate meal. When used as in the meaning of a festival, most often refers to a religious festival rather than a film or art festival.
