The New Year's Eve celebration held in Rio de Janeiro, Brazil, is called Réveillon.
Rio's Réveillon is especially famous for the enormous public gathering on Copacabana Beach. Millions of people may attend the wider celebration, which traditionally features music, white clothing, fireworks, and tributes to Yemanjá, an important figure in Afro-Brazilian religious traditions.
Many attendees wear white as a symbol of peace and renewal. Some also make offerings of flowers to the sea, although practices vary among participants and religious communities. Fireworks are launched from barges offshore, creating a display visible along the beach.
In French, réveillon generally refers to a late festive meal or celebration held on Christmas Eve or New Year's Eve. In Brazil, the word became the established name for the country's New Year's festivities, so it should not be confused with Carnaval, which takes place later and has a different historical and cultural context.
