Réveillon is the New Year's Eve event in Rio de Janeiro that traditionally features people wearing white on Copacabana Beach.
In Brazil, Réveillon refers to New Year's Eve celebrations, and Rio's Copacabana gathering is its most internationally famous example. Millions of people may attend the beach festivities in peak years, with concerts, fireworks, and religious or cultural offerings.
White clothing is associated with peace and renewal, although attendees may wear other colors for symbolic wishes. Many people also honor Afro-Brazilian traditions by making offerings to Iemanjá, a sea-associated deity, often involving flowers.
The celebration is not the same as Carnaval, which takes place later and has a different calendar and traditions. Event details, crowd sizes, and fireworks arrangements vary annually.
