Acre Time (ACT) operates at UTC−5 hours and is used in the Brazilian state of Acre as well as in some southwestern municipalities of Amazonas. Sometimes referred to as "Acre Standard Time," ACT does not observe daylight saving time and remains consistent throughout the year to match regional needs in Brazil's far-western Amazon region.
Importance and Global Use of ACT
ACT is vital for supporting the daily routines, public services, and economic activities in Acre and remote southwestern Amazonas. Its stable UTC−5 offset helps coordinate transportation, healthcare, and education services across a region with challenging geography and limited infrastructure.
Internationally, ACT facilitates reliable timing for trade, border cooperation, and environmental programs with Peru and Bolivia, Brazil's neighboring countries in the west. This consistent time zone also supports research, forest management, and conservation initiatives in one of South America's most biodiverse regions.
