BRT and UTC on the World Map
The map below highlights the BRT (Brasilia Time) and UTC (Coordinated Universal Time) timezone regions across the globe.
BRT – Brasilia Time
UTC-03:00Brasilia Time (BRT) is the time zone for eastern Brazil, 3 hours behind UTC.
- •Brazil abolished daylight saving time in 2019.
- •São Paulo is the largest city in the Southern Hemisphere.
- •BRT is 2 hours ahead of EST.
- •Brazil spans four different time zones.
- •The B3 stock exchange in São Paulo operates on BRT.
UTC – Coordinated Universal Time
UTC+00:00Coordinated Universal Time (UTC) is the world's primary time standard, used as the basis for civil time worldwide.
- •UTC is the basis for all civil time zones worldwide.
- •The abbreviation 'UTC' is a compromise between English (CUT) and French (TUC).
- •UTC is based on atomic clocks and is accurate to within a nanosecond per day.
- •Servers and databases worldwide store timestamps in UTC to avoid timezone confusion.
- •Leap seconds are occasionally added to UTC to keep it aligned with Earth's rotation.
Time Conversion Guide: BRT to UTC
BRT runs on Brasilia Time (BRT) at UTC-03:00. UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. That puts BRT 3 hours ahead of UTC — a difference of +3h at the current offsets.
In practice, when it is 9:00 AM in BRT it is 12:00 PM in UTC. Midnight in BRT is 3:00 AM in UTC. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert BRT to UTC time
- Scheduling a call from BRT to UTC: a 10:00 AM start in BRT lands at 1:00 PM in UTC, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both BRT and UTC are inside the 9-to-5 working day between 9:00 AM and 2:00 PM BRT time (12:00 PM–5:00 PM UTC). That is roughly 5 hours of usable overlap.
- Watching a live event or market open: BRT viewers need 12:00 PM in UTC to catch a 9:00 AM start there, and 9:00 PM if the event is anchored to BRT.
- Always state the zone abbreviation, not just the hour. "3:00 PM BRT" is unambiguous; "3 PM" across a +3h gap is not.
- Block 9:00 AM–2:00 PM BRT as the recurring meeting window if you work primarily from BRT and need UTC colleagues present.
About BRT (Brasilia Time)
Brasilia Time (BRT) is the standard time in the most populous regions of Brazil, including São Paulo, Rio de Janeiro, and the capital Brasília. Brazil abolished daylight saving time in 2019, so BRT is now observed year-round in these regions. Brazil spans four time zones in total.
About UTC (Coordinated Universal Time)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.
Best time to call between BRT and UTC
Both BRT and UTC sit inside the 9 AM – 5 PM working day between 9:00 AM–2:00 PM BRT, which is 12:00 PM–5:00 PM UTC. That gives roughly 5 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
BRT and UTC share 5 hours of working-hours overlap (9:00 AM–2:00 PM BRT), so scheduling a live meeting is straightforward.
BRT is 3 hours ahead of UTC (BRT UTC-03:00 → UTC UTC+00:00). The shared working window is 9:00 AM–2:00 PM BRT. Remember to re-check around daylight-saving transitions.
