Frequently Asked Questions
What is the time difference between UTC and BRT?
During standard time, Brasília Time is 3 hours behind Coordinated Universal Time.
Does Brazil observe Daylight Saving Time?
Brazil officially abolished Daylight Saving Time by presidential decree in April 2019, ending a practice that had been observed in the country's southeastern states since 1985. BRT has remained fixed at UTC-3:00 every day of the year since then, meaning the B3 stock exchange, federal government, and all Brazilian commercial operations run on a permanent, unchanging offset.
Is BRT the same as Argentina Time (ART)?
BRT (Brasília Time) and ART (Argentina Time) share the identical UTC-3:00 offset and neither country observes Daylight Saving Time, making São Paulo and Buenos Aires permanently synchronized on the same clock. Despite the different official designations, a meeting set for 10:00 BRT in São Paulo falls at exactly 10:00 ART in Buenos Aires — a fixed relationship that never shifts seasonally.
