The massive New Year's Eve street festival in Rio de Janeiro is called Réveillon.
Rio's Réveillon is centered on Copacabana Beach, where huge crowds gather for concerts, fireworks, and midnight celebrations. Many participants wear white, a color commonly associated with peace and good wishes, and some honor traditions connected with Afro-Brazilian religions by making offerings to the sea.
The Portuguese word “réveillon” is used in Brazil for New Year's Eve celebrations and also appears in other Portuguese- and French-speaking contexts. In Rio, the name refers to a large public festival rather than only a private dinner.
The event's scale and setting can lead to confusion with Brazil's Carnival. Carnival is a separate festival held before Lent, while Réveillon marks the transition from December 31 to January 1.
