About BST
A fixed, year-round offset.
Brasilia Standard Time (BST) covers eight major Brazilian cities, all fixed at UTC-03:00 year-round—no daylight saving adjustments needed. Whether you're coordinating across São Paulo, Recife, or Araguaina, scheduling stays simple and predictable.
IANA zones · the technical identifiers
The 8 zones that resolve to BST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about BST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Why doesn't Brasilia Standard Time observe daylight saving time?
- Brazil abolished daylight saving time in 2019, so all BST zones now stay on UTC-03:00 permanently, eliminating seasonal clock changes.
- How many cities share the same time in this region?
- Eight major Brazilian cities—including São Paulo, Recife, and Fortaleza—all follow Brasiana Standard Time, making nationwide coordination seamless.
- Is Brasilia Standard Time the same across all of Brazil?
- No—Brazil spans multiple time zones, but BST specifically covers these eight zones in the eastern and northeastern parts of the country.
- What’s the benefit of a fixed UTC offset like BST?
- A consistent offset simplifies travel, business planning, and digital scheduling across regions without worrying about seasonal time shifts.
- When was the last time BST changed its offset?
- The current UTC-03:00 offset has been stable since May 30, 2021, with no planned changes.
- Can I use BST for international meetings with Brazil?
- Yes—since BST doesn’t shift, you can reliably schedule calls or events with Brazilian partners without checking for DST updates.
- Which country uses Brasilia Standard Time?
