Daylight Saving Time Ends November 1, 2026: Who Falls Back and Who Stopped

Daylight saving time ends in most of the United States and eastern Canada at 2:00 a.m. local time on Sunday, November 1, 2026. Clocks go back one hour to 1:00 a.m., so the hour from 1:00 to 2:00 a.m. happens twice. Phones and computers change on their own. Set the oven, the car, and any wall clock back one hour before bed on Saturday night.

This year the bigger story is in Canada. British Columbia, Alberta, Manitoba, the Northwest Territories, and northwestern Ontario will not fall back this weekend. They have ended clock changes and are staying on what used to be summer time. The United States has not. The Sunshine Protection Act passed the House in July 2026, but the Senate has not voted on it.

When exactly do clocks fall back?

Federal law sets the date. Under the Uniform Time Act (15 U.S.C. 260a), daylight saving time runs from 2:00 a.m. on the second Sunday in March to 2:00 a.m. on the first Sunday in November. NIST lists the 2026 period as March 8 to November 1.

Each time zone changes at its own 2:00 a.m. New York falls back first. Chicago follows an hour later, then Denver, then Los Angeles, then Anchorage. Honolulu and Phoenix do nothing.

Daylight saving time starts again on Sunday, March 14, 2027, the second Sunday in March. It ends again on Sunday, November 7, 2027.

What time it will be in major US cities

The last column shows one fixed instant, 12:00 noon UTC on Monday, November 2, as each city will see it after the change.

Two states split across zones. In Texas, the federal time zone boundary in 49 CFR Part 71 runs along the east line of Hudspeth County, so El Paso and Hudspeth County are on Mountain time. In Florida, the line follows the Apalachicola River, so the panhandle west of it, including Pensacola and Panama City, is on Central time.

Who in the US does not change clocks

According to NIST, Hawaii, American Samoa, Guam, Puerto Rico, the U.S. Virgin Islands, and most of Arizona stay on standard time all year. The exception inside Arizona is the Navajo Nation, which does observe daylight saving time. The Hopi reservation, which the Navajo Nation surrounds, does not, as Arizona reporting explains. Driving across northeastern Arizona can mean changing time several times in under 100 miles.

Federal law lets a state opt out of daylight saving time and stay on standard time all year. It does not let a state stay on daylight time all year.

What time it will be in Canada

In Canada, provinces and territories set their own time rules, as the National Research Council notes. That is why half the country is skipping this fall back.

The practical effect from Sunday onward: Winnipeg shares a clock with Toronto, Calgary shares one with Regina and Chicago, and Vancouver sits one hour ahead of Seattle until March. Lloydminster, on the Alberta and Saskatchewan border, follows Alberta.

Who is ending clock changes, and what the law says

Canada: five jurisdictions have stopped this year

• British Columbia. The Attorney General announced on March 2, 2026 that the March 8 spring forward was the province's final time change. B.C. brought into force the Interpretation Amendment Act, passed in 2019 and never used, and now keeps Pacific time at UTC-7 all year.
• Alberta. The province says it has adopted permanent Alberta Time, the old Mountain Daylight Time, at UTC-6. The tz database maintainers record that the change became law on June 18, 2026.
• Northwest Territories. Premier R.J. Simpson announced on September 23 that the territory is ending seasonal time changes and will keep Northwest Territories time year-round, matching Alberta.
• Manitoba. Premier Wab Kinew signed a proclamation in September. On October 29 the province reminded residents that clocks will not change this weekend, as Manitoba moves to permanent daylight time, now called Manitoba Standard Time.
• Northwestern Ontario. Ontario said it would use a regulation under its Time Act so communities west of the 90th meridian, such as Kenora, stay aligned with Manitoba. The rest of Ontario still falls back.

Ontario passed a law in 2020 to make daylight time permanent across the province. It has not taken effect because, as CTV reports, it depends on Quebec and New York State making the same move. Quebec may be next. On October 28, Premier Paul St-Pierre Plamondon said this weekend is "very likely" the last time Quebecers turn their clocks back. No bill has been tabled. He plans a parliamentary committee to decide between permanent daylight and permanent standard time.

Yukon stopped in 2020 and stays at UTC-7. Most of Saskatchewan has not changed its clocks since 1966.

United States: no state stops this year

No US state is changing its clocks for the last time this weekend. The National Conference of State Legislatures counts 19 states with laws for year-round daylight saving time, including Florida (2018), Washington (2019), Colorado (2022), and Texas (2025). Every one of them is conditional. Each takes effect only if Congress changes federal law. NCSL lists no new state law enacted in 2026. California voters approved Proposition 7 in 2018, which lets the legislature act by a two-thirds vote, but the legislature has not acted.

The federal bill did move this year. The House passed H.R. 139, the Sunshine Protection Act of 2025, on July 14, 2026, by 308 to 117. The Senate received it the next day and sent it to the Commerce, Science, and Transportation Committee, where it sits. The Senate version, S. 29, has had no action since January 2025.

The House-passed text repeals the March to November period and moves every zone's standard time one hour forward, which makes daylight time permanent. States already exempt, such as Hawaii and Arizona, could keep their current time or take the new one. Until the Senate passes it and the President signs it, nothing changes.

Elsewhere

Mexico stopped observing daylight saving time in 2022 except near the US border, according to the IANA time zone database. The same source records two changes this season. Cuba will not fall back on November 1 and plans to stay on UTC-4 until November 7, 2027. Morocco moved to permanent UTC+0 on September 20, 2026.

Where daylight saving time applies right now

Europe has already switched. The EU's summer-time directive ends summer time on the last Sunday in October, and the UK government lists October 25, 2026 for Britain. For this one week, London is four hours ahead of New York instead of five.

The southern hemisphere is in its summer time now. New Zealand moved its clocks forward on September 27, 2026 and goes back on April 4, 2027. In Australia, New South Wales, Victoria, South Australia, Tasmania, and the ACT started on October 4, 2026 and end on April 4, 2027. Queensland, Western Australia, and the Northern Territory do not observe it. After Sunday, Sydney (UTC+11) is 19 hours ahead of Los Angeles (UTC-8).

A short history of the clock change in the US

• 1918. The Standard Time Act, also called the Calder Act, set up US time zones and introduced daylight saving time.
• 1942 to 1945. President Franklin Roosevelt put the country on year-round "War Time" from February 9, 1942 to September 30, 1945.
• 1966. The Uniform Time Act set national start and end dates and gave states the right to opt out.
• 2005. The Energy Policy Act moved the dates to March and November from 2007. NIST notes that daylight time now lasts 238 days, about 65 percent of the year.

What the clock change breaks in software

I have spent 15 years building identity and security systems, and the clock change is one of the few bugs that arrives on a calendar.

• Cron jobs in the repeated hour. A job set for 1:30 a.m. local time can run twice on Sunday, depending on the scheduler. In March the mirror problem appears: a job set for 2:30 a.m. can be skipped, because that time never happens.
• Expiry math in local time. "Same time tomorrow" and "24 hours from now" differ by an hour across a transition. Token and certificate formats avoid this: a JWT's exp claim is seconds since the epoch under RFC 7519, and RFC 5280 encodes certificate validity dates in UTC. Bugs come from the code around them. My JWT, OAuth, OIDC, and SAML guide covers how those claims work.
• Log correlation. On Sunday, 1:15 a.m. happens twice. Logs stamped in local time without an offset cannot be ordered, and incident timelines across regions drift by an hour.
• Stale time zone data. This year matters more than most. The IANA tz database shipped the British Columbia, Alberta, Northwest Territories, and Manitoba changes across releases 2026b to 2026e, and Cuba's in 2026f on October 27. A server or container with older tzdata will move Vancouver, Edmonton, and Winnipeg back an hour on Sunday when the real clocks do not. Manitoba's own release tells people to update their devices.
• MFA codes are fine. TOTP, the six-digit codes from an authenticator app, is defined in RFC 6238 on Unix time, the count of seconds since midnight UTC on January 1, 1970. The clock change does not touch it. I explain how those factors fit together in my 2FA and MFA guide.

I learned this on my own site. This blog publishes on two editorial windows pinned to San Francisco time, 08:30 and 20:30. The scheduling tool used to subtract a fixed eight hours and label the result PST. That is only right for the four months the Bay Area is on standard time. For the other eight months, on PDT, the 08:30 window published at 09:30. The fix was to store every publish time in UTC and convert with the America/Los_Angeles zone, so the local time holds all year and the stored UTC value moves instead.

A short checklist:

1. Store and log timestamps in UTC, or with an explicit offset.
2. Schedule in a named IANA zone such as America/Chicago, never a fixed offset like UTC-6.
3. Keep recurring jobs out of the 1:00 to 3:00 a.m. local window, or run them in UTC.
4. Update tzdata on servers, containers, and language runtimes, especially for Canadian users.
5. Test the transition. Run your scheduler against November 1 and March 14 before they happen.

FAQ

What time does daylight saving time end in California?

At 2:00 a.m. Pacific Daylight Time on Sunday, November 1, 2026. Clocks go back to 1:00 a.m. Pacific Standard Time, and California moves from UTC-7 to UTC-8.

Does Arizona change its clocks?

Most of Arizona does not. It stays on Mountain Standard Time, UTC-7, all year. The Navajo Nation in the northeast does change its clocks, and the Hopi reservation inside it does not.

When does Canada fall back?

Ontario, Quebec, the Atlantic provinces, Newfoundland and Labrador, and Nunavut fall back at 2:00 a.m. local time on November 1, 2026. British Columbia, Alberta, Saskatchewan, Manitoba, Yukon, the Northwest Territories, and northwestern Ontario do not.

Is daylight saving time being abolished in the US?

Not yet. The House passed the Sunshine Protection Act on July 14, 2026, which would make daylight time permanent. The Senate has not voted on it, so the March and November changes continue.

When does daylight saving time start again?

Sunday, March 14, 2027, at 2:00 a.m. local time, when clocks jump ahead to 3:00 a.m. It then ends on Sunday, November 7, 2027.

Do I need to change my phone or computer?

No, if automatic time is on and the device is up to date. That matters most in Canada this year, because an old time zone file can roll back the clock in a province that no longer changes.
