When does US daylight saving time start and end in 2026?

It starts on March 8, 2026 (second Sunday of March) and ends on November 1, 2026 (first Sunday of November).

Which US states don't observe daylight saving time?

Hawaii and Arizona (except the Navajo Nation). Puerto Rico, the US Virgin Islands, Guam, American Samoa, and Northern Mariana Islands also stay fixed.

How does US DST affect the time difference with Brazil?

Brazil does not observe DST, so when the US springs forward in March the gap with Brasília shrinks by 1 hour. In November, when the US falls back, the gap grows by 1 hour.

Will the US abolish daylight saving time?

There has been a proposal called the Sunshine Protection Act under discussion in Congress for years, but it has not been passed by both chambers. For now, DST remains in effect.

USA daylight saving time 2026: official dates and what changes

May 2026

Daylight Saving Time (DST) in the United States is one of the most disruptive seasonal changes for anyone who travels, works with, or has family in the US. In 2026 the rule is the same as always: spring forward in March, fall back in November.

Official US DST dates in 2026

Start (spring forward): Sunday, March 8, 2026 — at 2am, clocks jump to 3am.
End (fall back): Sunday, November 1, 2026 — at 2am, clocks fall back to 1am.

Under the Energy Policy Act of 2005, the change always falls on the second Sunday of March and the first Sunday of November.

Which states don't change clocks?

Two states and several US territories do not observe DST:

Hawaii — stays at UTC-10 year-round.
Arizona — stays at Mountain Standard Time (UTC-7) year-round, except the Navajo Nation, which does observe DST.
Puerto Rico, US Virgin Islands, Guam, American Samoa, and Northern Mariana Islands also stay fixed.

In US summer, Arizona shares California's clock. In winter, Arizona is 1 hour ahead of California.

How US DST affects callers in Brazil

Brazil has no DST since 2019, so Brasília is fixed at UTC-3 year-round. The US moves clocks twice a year. The result: the gap between Brazil and the US shifts by one hour at each DST boundary.

In 2026:

Before March 8, 2026 (US winter): New York 2h behind Brasília, Los Angeles 5h behind, Chicago 3h behind.
Between March 8 and November 1 (US summer): New York 1h behind, Los Angeles 4h behind, Chicago 2h behind.
After November 1, 2026: back to winter offsets.

Is the US going to end daylight saving time?

There is recurring political pressure to abolish the clock change. The Sunshine Protection Act, which would make DST permanent nationwide, passed the Senate in 2022 but did not advance in the House. As of writing, DST remains in effect on the current schedule. Verify official sources for the latest status.

How to avoid scheduling mistakes around US DST in 2026

Mark the two critical dates in your calendar: March 8 and November 1, 2026.
Always confirm the time zone when scheduling — say 'Eastern Time' or 'Pacific Time', not just 'US time'.
Use tools like QueHoras that adjust automatically for DST so you never have to do clock math.
