North America stretches from the Arctic islands of Canada to the narrow land bridge of Panama, and its clocks reflect that huge north to south, east to west spread. What makes the continent especially interesting to follow right now is not just its standard offsets, but how many of its governments are actively rewriting their daylight saving time rules in 2026, some already in effect and some still stuck in legislative limbo.
How many time zones does North America have
North America’s mainland spans six primary standard time zones, from Newfoundland Time at UTC−03:30 in eastern Canada to Hawaii-Aleutian Time at UTC−10:00 in the mid-Pacific [1, 2]. Add Alaska in the far northwest and Greenland, which is geographically part of North America though politically tied to Denmark, and the continent’s full range stretches even wider.
Unlike Africa, where most countries keep the same offset all year, and similar to much of Europe, most of the United States, Canada, and Mexico still shift their clocks for part of the year under some form of daylight saving time, though this is changing rapidly in parts of the continent, as the next sections explain.
The full list, zone by zone
UTC−10:00, Hawaii-Aleutian Standard Time
Hawaii is one of only two US states, along with most of Arizona, that does not observe daylight saving time and stays on this offset all year round.
UTC−09:00 and UTC−08:00, Alaska Time
Most of Alaska uses UTC−09:00 in standard time and shifts to UTC−08:00 during daylight saving time, alongside the rest of the United States’ seasonal clock change.
UTC−08:00, Pacific Standard Time
- Most of the western United States
- Western Canada, including most of British Columbia in standard time
- Northwestern Mexico’s Baja California state, which aligns with US Pacific Time [8]
UTC−07:00, Mountain Standard Time and permanent Pacific Time
This band currently includes some of the most significant, live changes on the continent.
- Arizona, apart from the Navajo Nation, which observes DST separately, has kept a permanent UTC−07:00 offset for decades and does not observe daylight saving time [1]
- Yukon, a Canadian territory, abolished seasonal clock changes in 2020 and has stayed on UTC−07:00 year round ever since, effectively adopting permanent daylight saving time [1, 2]
- British Columbia brought a 2019 law into force starting 8 March 2026, moving the province to permanent Pacific Daylight Time at UTC−07:00 and choosing not to fall back to standard time that November [2, 3]. This decision was contingent on neighboring US West Coast states making a similar change, but British Columbia proceeded regardless [2]
UTC−06:00, Central Standard Time and permanent Mountain Time
- Most of the central United States
- Saskatchewan, a Canadian province that has observed permanent Central Standard Time for decades, alongside neighboring Alberta and Saskatchewan’s shared logic of avoiding seasonal changes [3]
- Alberta, which passed the Red Tape Reduction Statutes Amendment Act in 2026, officially proclaimed into force on 18 June 2026, ending the province’s Daylight Saving Time Act and replacing it with a new Official Time Act [3]. Importantly, this change takes effect from November 2026, meaning Alberta remains on its normal seasonal Mountain Daylight Time through the rest of 2026 before it stops falling back for the first time [3]
- The Northwest Territories, a Canadian territory that adopted permanent Central Time on 21 August 2026, moving away from seasonal Mountain Time [1]
- Most of central Mexico, in the country’s Zona Centro [8]
UTC−05:00, Eastern Standard Time and permanent Central Time
- Most of the eastern United States
- Eastern Canada, including Ontario and Quebec
- Quintana Roo, the Mexican state that includes Cancun, which keeps a permanent UTC−05:00 offset year-round without daylight saving time, aligning it with US Eastern Time [8]
- Large parts of the Caribbean and Central America that do not observe daylight saving time at all
UTC−04:00, Atlantic Standard Time
- The Atlantic Canadian provinces, including Nova Scotia and New Brunswick, in standard time
- Several Caribbean islands, which use this offset permanently without any seasonal shift
UTC−03:30, Newfoundland Standard Time
Newfoundland is North America’s only widely used time zone with a 30-minute offset rather than a full hour, making it 30 minutes ahead of the neighboring Atlantic zone.
The big 2026 story: western Canada is quietly ending the clock change, province by province
This is the most significant and fastest-moving story in North American timekeeping right now, and it deserves careful, dated explanation because different parts of it are at different legal stages.
British Columbia’s change is already fully in effect. The province brought a bill first passed in 2019 into force starting 8 March 2026, moving to permanent Pacific Daylight Time and confirming it would not shift back to standard time that November [2, 3]. This aligned British Columbia with the Yukon, which has kept a permanent UTC−07:00 offset since 2020 [1, 2]. Following that regional shift, the Regional District of East Kootenay in southeastern British Columbia also moved from Mountain Time to Central Time year round on 14 August 2026, to stay aligned with neighboring Alberta rather than the rest of British Columbia [2].
The Northwest Territories’ change is also already in effect. The territory moved from seasonal Mountain Time to a permanent Central Time offset on 21 August 2026 [1].
Alberta’s change is legally official but not yet active on the clock. Alberta’s provincial government introduced Bill 31, the Red Tape Reduction Statutes Amendment Act, on 23 April 2026, proposing to repeal the old Daylight Saving Time Act and replace it with a new Official Time Act establishing a permanent UTC−06:00 standard, branded locally as Alberta Time [3]. The relevant sections of this act were formally proclaimed into force on 18 June 2026 [3]. However, the actual change to Albertans’ clocks is scheduled to begin in November 2026, meaning that as of this article’s publication, Alberta is still observing its normal seasonal Mountain Daylight Time and will simply not fall back this coming autumn [3]. This is worth stating clearly, since some secondary sources describe Alberta as though the change has already happened, when the legal mechanism and the actual clock change are two separate milestones.
Notably, this reform arrives after a 2021 Alberta referendum on the same question failed narrowly, with 50.2 percent of voters choosing to keep the twice-yearly clock change rather than adopt a permanent time. The 2026 legislative change proceeds despite that earlier result not favoring it.
The big 2026 story south of the border: the US House passes the Sunshine Protection Act
This is the second major, still unresolved story worth tracking closely, since news coverage of it can easily be mistaken for a completed change.
On 14 July 2026, the US House of Representatives passed the Sunshine Protection Act, House Resolution 139, by a vote of 308 to 117, a bill that would make daylight saving time permanent nationwide and end the twice yearly clock change [6]. The bill would not affect Hawaii or most of Arizona, which do not observe daylight saving time in the first place [6].
As of this article’s publication, however, the bill has not become law. It still requires passage in the US Senate, where a 60-vote threshold is needed, and Senate Majority Leader John Thune has said senators remain divided on whether that threshold can be reached [7]. No Senate vote had been scheduled as of the most recent reporting available [7]. If the Senate does pass the bill and the President signs it, the United States would stop changing its clocks and stay on daylight saving time permanently, but until that happens, the twice yearly change remains the legally current system nationwide outside of Hawaii and most of Arizona.
This is a useful case study in exactly the kind of documented fact versus premature assumption this article tries to separate throughout. A bill passing one chamber of a legislature is real, sourced, documented news, but it is not the same as a change actually taking effect, and readers should treat the two as separate facts rather than assuming the second follows automatically from the first.
Daylight saving time in Mexico
Mexico abandoned most of its daylight saving time practice on 30 October 2022, with certain exceptions [1]. Municipalities along Mexico’s northern border with the United States continue to observe seasonal clock changes, so that their local business hours stay synchronized with neighboring US border towns, even though the rest of the country no longer shifts its clocks [1].
Myth versus documented fact
| Claim | Status |
|---|---|
| “Alberta has already stopped changing its clocks” | Partly myth. The legal change is official as of June 2026, but the actual switch to permanent time takes effect from November 2026, so Alberta is still on its normal seasonal schedule at the time of this article’s publication [3]. |
| “The United States has made daylight saving time permanent” | Myth. The House passed the Sunshine Protection Act in July 2026, but it has not passed the Senate or been signed into law, so the twice yearly change remains current federal policy outside Hawaii and most of Arizona [6, 7]. |
| “All of Mexico stopped observing daylight saving time in 2022” | Partly myth. Most of the country did, but towns along the US border kept seasonal clock changes to stay aligned with their US neighbors [1]. |
| “Every Canadian province and territory still changes its clocks twice a year” | Outdated. Yukon has kept permanent daylight time since 2020, British Columbia and the Northwest Territories joined in 2026, and Alberta’s change is legally set to begin in November 2026 [1, 2, 3]. |
| “Arizona is the only US state that skips daylight saving time” | Myth. Hawaii also does not observe daylight saving time, and has not for decades. |
Why some places chose to keep or drop the clock change
The debate playing out in Alberta and the US Congress echoes arguments made across the world. Supporters of permanent daylight saving time generally argue it reduces evening darkness, supports outdoor economic activity, and avoids the brief spike in traffic accidents that tends to follow the spring clock change [6]. Opponents, including some US senators cited in recent coverage, point to the United States’ brief and unpopular experiment with year round daylight saving time in 1974, when early morning darkness in winter became a significant public complaint, as a cautionary precedent [7].
Canada’s Yukon and British Columbia, by contrast, chose permanent daylight time specifically to preserve more useful daylight hours in the evening throughout the year, a decision that matters more at their northern latitudes where winter daylight hours are especially short [1, 2].
Why this matters for readers outside North America
For readers in Africa or Asia coordinating with North American partners, the practical takeaway is that this is currently one of the most unstable timekeeping regions in the world to schedule against. A call time that works with Alberta or the rest of the United States today could shift by an hour later this year, depending on how these still unresolved legislative processes conclude.
The safest approach for anyone with a recurring or high-stakes commitment involving North America is to check a live, dated time zone source close to the date of the call or meeting, rather than relying on a fixed mental note of the offset, since several of the changes described in this article are only weeks or months old at the time of writing.
