The New Year's Eve celebration featuring fireworks over Copacabana Beach in Rio de Janeiro is called Réveillon.
In Brazil, Réveillon refers to New Year's Eve celebrations generally, and Rio de Janeiro's event at Copacabana is its most internationally famous example. Huge crowds gather along the beach for concerts, religious and cultural customs, and a midnight fireworks display over the Atlantic Ocean.
Many participants wear white, a color associated with peace and renewal. Some people also make offerings to Iemanjá, an ocean-associated figure honored in Afro-Brazilian religious traditions, although customs vary among individuals and communities.
Réveillon is not the same event as Rio's Carnival. Carnival is held later and is associated with samba parades and pre-Lenten festivities, while Réveillon marks the change from December 31 to January 1.
