Horario de Brasilia is the time zone used in Brazil during the summer months. It is three hours behind Coordinated Universal Time (UTC), and one hour ahead of Eastern Time in the United States. Horario de Brasilia is observed in most of Brazil, except for the states of Amazonas, Roraima, and part of Par, which observe UTC-5.
Horario de Brasilia was first introduced in 1931, and it has been in use ever since. The time zone is important for Brazil because it helps to coordinate business hours, travel, and other activities. Horario de Brasilia is also important for the country’s economy, as it helps to ensure that Brazil is on the same time schedule as its major trading partners.
