Rio de Janeiro's New Year's Eve festival is called Réveillon.
In Brazil, Réveillon refers to the New Year's Eve celebration, and Rio's event on Copacabana Beach is among the world's largest annual public parties. The beachfront gathering combines concerts, fireworks, religious and cultural customs, and crowds dressed predominantly in white.
The white clothing is commonly associated with peace and renewal and also reflects Afro-Brazilian religious traditions connected with honoring Iemanjá, the sea deity. Many participants place flowers or offerings on small boats or send them toward the ocean, although practices vary among individuals and communities.
Rio's fireworks are launched from barges offshore so the display can be seen along the beach. The celebration attracts visitors from Brazil and abroad, but Réveillon is not exclusive to Rio: the word is used nationally for New Year's Eve festivities in many Brazilian cities.
