Most of Brazil operates on Brasília Time (BRT), which is 3 hours behind Coordinated Universal Time (UTC-3). Since 2019, Brazil no longer observes daylight saving time, so the time remains consistent throughout the year. Brazil spans four time zones due to its vast size.
Major cities including São Paulo, Rio de Janeiro, Brasília, Belo Horizonte, and Salvador all follow Brasília Time (UTC-3). Western states like Acre use UTC-5, while the Fernando de Noronha archipelago uses UTC-2. The Amazon region uses UTC-4.
Brazil is the largest country in South America and the fifth-largest in the world. São Paulo is the largest city in the Southern Hemisphere with over 12 million residents. Brazil is the only Portuguese-speaking country in South America and is home to the Amazon rainforest, which produces about 20% of the world's oxygen.
