Time in Brazil
standard timezone in Brazil, equivalent to UTC-03:00
Time in Brazil is calculated using standard time, and the country (including its offshore islands) is divided into four standard time zones: Fernando de Noronha time (UTC−02:00), Brasília time (UTC−03:00), Amazon time (UTC−04:00), and Acre time (UTC−05:00). About 93% of the Brazilian population live in Brasília time (UTC−03:00).
Time zones
Fernando de Noronha time (UTC−02:00)
This is the standard time zone only on a few small offshore Atlantic islands. The only such island with a permanent population is Fernando de Noronha, with 3,167 inhabitants (2022 census), 0.0016% of Brazil's population. The other islands (Trindade and Martim Vaz, Rocas Atoll and Saint Peter and Saint Paul Archipelago) either are totally uninhabited or have small seasonally rotating Brazilian Navy garrisons or teams of scientists.
Brasília time (UTC−03:00)
The main time zone of Brazil comprises the states in the South, Southeast and Northeast regions (except the small islands mentioned above), plus the states of Goiás, Tocantins, Pará and Amapá, and the Federal District, which includes the national capital city, Brasília. About 93% of the Brazilian population live in this time zone, which covers about 60% of the country's land area.
Amazon time (UTC−04:00)
This time zone is used in the states of Mato Grosso, Mato Grosso do Sul, Rondônia, Roraima, and most of Amazonas. Although this time zone covers about 36% of the land area of Brazil (an area larger than Argentina), only about 6% of the country's population live there (about 12 million people, slightly more than the city of São Paulo).
Until 2008, the part of the state of Pará west of the Jari and Xingu rivers was also part of this time zone; then it joined the rest of the state in observing Brasília time (UTC−03:00).

Why this record matters
A short description can identify a subject without explaining its stakes. For “Time in Brazil”, the useful work is to connect “standard timezone in Brazil, equivalent to UTC-03:00” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 17, 2025. The linked authority identifier is Q187183. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2022 and 2008.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
