How to Convert ACT to Other Time Zones
Open the ACT converter page: Go to https://www.xconvert.com/time-converter/act-time-zone to load the visual comparison grid with ACT (Acre Time, UTC-5) already shown as the base row. This page is useful when you need to line up working hours in western Brazil with teams in North America or Europe, especially for logistics, cross-border trade, or remote support schedules.
Add comparison cities: Click + Add City and search for cities that commonly interact with UTC-5 regions, such as New York, Bogotá, and London. New York matters for finance and corporate calls, Bogotá shares the same standard offset year-round, and London is a common reference point for multinational companies coordinating Latin America with Europe.
Select a time range on the grid: Click Select if needed, then drag across the ACT row from 9:00 AM to 11:00 AM to highlight a meeting window in purple. That selection shows immediately how ACT compares elsewhere: 9:00–11:00 AM ACT is 10:00 AM–12:00 PM in New York during U.S. Eastern Daylight Time, 9:00–11:00 AM in Bogotá year-round, and 2:00–4:00 PM in London during UK standard time, helping you confirm whether a morning call in Acre overlaps with business hours abroad.
Export and share the result: After selecting the range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially useful if you are scheduling a supplier call, sending a handoff window to a distributed operations team, or sharing a meeting slot so each participant sees the correct local time automatically.
About Acre Time (ACT)
ACT stands for Acre Time, the time standard associated with the Brazilian state of Acre and nearby western parts of the Amazon region. Its exact UTC offset is UTC-05:00, which means local clock time in ACT is 5 hours behind Coordinated Universal Time.
In practical terms, when it is 12:00 UTC, it is 7:00 AM ACT. Because ACT is a fixed UTC-5 time zone, it aligns with several other non-DST and seasonally matching zones at different times of year, including COT (Colombia Time) and PET (Peru Time) year-round, while it may temporarily match parts of the United States Eastern or Central systems depending on their daylight saving status.
ACT is used in Brazil, specifically in the far western part of the country. The best-known region is the state of Acre, which borders Peru and Bolivia, placing it geographically and economically closer in daily rhythm to western Amazon trade corridors than to Brazil’s Atlantic coast cities such as São Paulo or Rio de Janeiro.
Because Brazil spans multiple time zones, ACT is 2 hours behind Brasília Time (BRT, UTC-3). That means when it is 9:00 AM in Acre, it is already 11:00 AM in Brasília, a difference that matters for federal deadlines, banking cutoffs, airline itineraries, and internal coordination across Brazilian offices.
ACT and Daylight Saving Time
Acre Time does not currently observe daylight saving time. The data for this page is DST: false, so ACT remains on UTC-05:00 all year and does not switch to a summer time counterpart.
For the current year, 2026, there are no DST transition dates for ACT: clocks do not move forward in March or October, and they do not move back later in the year. This makes ACT easier to use for recurring schedules within its own region, because the local offset from UTC stays constant every day of the year.
However, the difference between ACT and other regions can still change seasonally because other time zones do observe DST. For example, ACT is typically 1 hour behind New York when the U.S. is on Eastern Daylight Time (UTC-4), but the same as U.S. Eastern Standard Time (UTC-5) when daylight saving is not active there; similarly, ACT is 5 hours behind London during UK winter time (UTC+0) and 6 hours behind London during British Summer Time (UTC+1).
This matters for recurring international meetings. A weekly call fixed at 10:00 AM ACT stays at 10:00 AM in Acre year-round, but it will appear at different local times for participants in cities such as New York, Toronto, London, or Madrid when those places enter or leave daylight saving time.
Frequently Asked Questions
What does ACT stand for?
ACT stands for Acre Time. It is the time zone used in Acre, Brazil, and its standard offset is UTC-05:00, meaning local time is five hours behind UTC.
Is ACT the same as GMT?
No, ACT is not the same as GMT. GMT is UTC+00:00, while ACT is UTC-05:00, so ACT is 5 hours behind GMT; for example, when it is 3:00 PM GMT, it is 10:00 AM ACT.
Which cities use ACT?
ACT is associated primarily with the Brazilian state of Acre, whose main urban center is Rio Branco, the state capital. Other localities in Acre also follow this time standard, and the zone is relevant for western Brazilian travel, government administration, and regional business schedules tied to the Amazon basin.
What is the UTC offset for ACT?
The UTC offset for ACT is UTC-05:00. This means you subtract 5 hours from UTC to get Acre Time, so 18:00 UTC becomes 13:00 ACT.
When does ACT change?
ACT does not currently change during the year because it does not observe daylight saving time. In 2026, there are no clock changes and no DST start or end dates for Acre Time, so the offset stays fixed at UTC-5 from January through December.
Is ACT the same as Eastern Time in the United States?
Not always. ACT matches U.S. Eastern Standard Time (EST, UTC-5) during the part of the year when the eastern United States is on standard time, but it differs by 1 hour when the U.S. switches to Eastern Daylight Time (EDT, UTC-4); in that season, 9:00 AM ACT equals 10:00 AM in New York.
Is ACT the same as Colombia Time or Peru Time?
Yes, ACT shares the same UTC-05:00 offset as Colombia Time (COT) and Peru Time (PET) throughout the year because those zones also generally do not observe daylight saving time. That means 8:00 AM in Acre is also 8:00 AM in Bogotá and Lima, which is useful for regional trade, aviation planning, and multilingual support coverage across northern and western South America.
