On November 1, 2026, the United States goes back to standard time: at 2:00 a.m. clocks move back to 1:00 a.m. If you work with US teams from Brazil, the time difference with Brasília changes — a classic cause of meetings scheduled at the wrong hour.
US daylight saving dates (2026 and 2027)
- Start in 2026: Sunday, March 8 (clocks forward 1 hour)
- End in 2026: Sunday, November 1 (clocks back 1 hour)
- Start in 2027: Sunday, March 14
The rule is fixed: US DST begins on the second Sunday of March and ends on the first Sunday of November, always at 2:00 a.m. local time.
What will the difference with Brasília be after November 1?
Brazil has had no daylight saving time since 2019, and Brasília stays at UTC−3 all year. Only the US side changes:
| City | Until Oct 31 (DST) | From Nov 1 (standard) |
|---|---|---|
| New York, Miami, Washington (Eastern) | Brasília is 1h ahead | Brasília is 2h ahead |
| Chicago, Dallas, Houston (Central) | Brasília is 2h ahead | Brasília is 3h ahead |
| Denver (Mountain) | Brasília is 3h ahead | Brasília is 4h ahead |
| Los Angeles, Seattle (Pacific) | Brasília is 4h ahead | Brasília is 5h ahead |
Example: a 3 p.m. meeting in New York, which today equals 4 p.m. in Brasília, will equal 5 p.m. in Brasília from November.
Note: Hawaii and most of Arizona do not observe DST, so their gap with Brasília is constant all year — and differs from the rest of the country for part of it.
The mismatch week: October 25 to November 1
Europe ends DST on October 25, 2026, one week before the US. During that week the US–Europe gap is 1 hour shorter than usual. Double-check meetings if you work with both sides.
Impact on markets and meetings
- US stock exchanges (NYSE, Nasdaq): open at 9:30 a.m. New York time all year; in Brasília that moves from 10:30 to 11:30 once the US returns to standard time. Check the exact window on market hours.
- Recurring meetings: calendar invites usually adjust themselves, but agreements made by message ("every day at 2 p.m.") do not. Always state the time zone.
- Support and customer service: if you serve US customers, review shift schedules before November 1.
