Rio Branco, Brazil · UTC-5
Convert time from Rio Branco
Rio Branco is in the Acre Time timezone (ACT/UTC-5), observed year-round with no daylight saving. Brazil’s westernmost state capital has its own timezone, one hour behind Manaus.
Acre is Brazil’s westernmost state, jutting into Peru and Bolivia in a geographic anomaly created by the rubber boom of the early 20th century. Brazil acquired it from Bolivia in 1903 after a conflict involving rubber tappers and Brazilian settlers. Rio Branco, the state capital, has its own timezone to match its unusual position.
Brazil uses multiple timezones, and Acre runs on ACT, Acre Time, UTC-5, year-round without daylight saving. This places Rio Branco one hour behind Manaus and two hours behind Brasília. The Amazon state (Amazonas) uses Amazon Time (UTC-4), making Acre’s extra westward extension justify the offset.
The Acre River runs through Rio Branco, giving the city its waterfront identity. The city is surrounded by the Amazon rainforest, and rubber extraction, though far from its peak, shaped the economy and culture. Chico Mendes, the rubber tapper and environmental activist murdered in 1988 for opposing deforestation, was from Acre. His work contributed to the creation of extractive reserves, protected areas where communities can continue traditional forest uses.
seasons and the Amazonian flood cycle
