Rio Branco

The Rio Branco time zone

Rio Branco (GMT-5) is the local time zone for Rio Branco, Cruzeiro Do Sul, Tarauacá and Sena Madureira, currently UTC-5 from Coordinated Universal Time. Its IANA identifier is America/Rio_Branco — the standard label software, operating systems, and World on Time use to track its rules and history. The live clock above reads from this zone’s official rules, so it stays correct through daylight saving changes and any future adjustments.

Daylight saving time

Rio Branco does not observe daylight saving time. Its offset stays fixed at UTC-5 all year, so there are no spring-forward or fall-back clock changes here. That makes it one of the simpler zones to schedule against — the time difference to any other fixed-offset zone never moves.

Working across this time zone

To convert a time into or out of GMT-5, use the buttons above or the time zone converter — it handles the offset math and any daylight saving shift for you. When you write a time for people in other zones, it helps to spell out the zone (for example, “3 pm GMT-5”) so there’s no ambiguity. For planning a call, the converter’s side-by-side view makes it easy to find an hour that lands during everyone’s working day.
