Acre uses Acre Time, UTC−5, throughout the year. The Brazilian state does not currently make seasonal daylight saving clock changes, and Rio Branco, Cruzeiro do Sul, Sena Madureira, and its other municipalities share that offset.

Current time in Acre, Brazil

The current time in Acre is five hours behind Coordinated Universal Time. When UTC is 15:00, Acre is at 10:00 on the same date. Near midnight, conversion can place Acre on the previous calendar day, so both hour and date should be checked.

Acre Time is commonly abbreviated ACT. It is one of the time standards used within Brazil, a country broad enough to span multiple time zones. Travelers should not assume that a clock set for another Brazilian state will necessarily match Acre.

Brazil may share a national flag, but it is far too wide to fit comfortably beneath one wall clock.

Rio Branco and Acre’s main cities

Rio Branco is the state capital and Acre’s principal urban centre. Cruzeiro do Sul is another major city and an important reference for the state’s western interior. Sena Madureira, Tarauacá, and Brasileia are also notable municipalities represented in geographic directories.

Rio Branco: state capital and primary time reference Cruzeiro do Sul: major city in western Acre Sena Madureira: municipality west of Rio Branco Tarauacá: municipality farther into the state Brasileia: municipality near the Bolivian border

These places use the same UTC−5 clock. Their physical separation can still produce differences in sunrise and sunset, because a shared legal time zone does not make their solar positions identical. Population rankings can change and depend on whether a source counts municipalities or urban areas. A place list is therefore better used for navigation than as a permanent statistical league table.

Sunrise from Rio Branco to Cruzeiro do Sul

Sunrise must be calculated for a particular city and date. Rio Branco is a sensible default for a statewide page because it is the capital, but a visitor in Cruzeiro do Sul should select that city for a more relevant daylight result.

Acre lies close to the equatorial part of South America, yet sunrise is not fixed at one minute throughout the year. Date, longitude, latitude, and the adopted UTC−5 offset all shape the clock reading attached to the event.

Choose the city nearest to the observation point. Confirm that Acre Time or UTC−5 is displayed. Check whether conversion changes the calendar date. Distinguish sunrise from twilight and first light. Forest, buildings, terrain, and cloud can affect when direct sunlight becomes visible. Those conditions do not alter the astronomical definition used by the calculator. For travel or outdoor work, combine the computed value with local conditions.

Questions and answers

What is Acre’s time-zone offset?: Acre uses UTC−5, known as Acre Time.
Is Acre always on the same time as Brasília?: No. Acre and Brasília use different standard offsets, so their local clocks do not match.
Do Rio Branco and Cruzeiro do Sul share one time zone?: Yes. Both use Acre Time, although their sunrise and sunset calculations can differ by location.
