Ancient Greek festivals were major religious events that recurred annually, every two years, or every four years. The purposes and rituals of the festivals varied a great deal, but all had in common the desire to maintain a good relationship with the gods. The festivals of Athens are best known, and they were plentiful: Athens set aside at least 60 days a year for annual festivals.
