Time zone map of the US & Canada

Eight time zones run from Newfoundland Time (UTC−3:30) to Hawaii–Aleutian Time (UTC−10). In the US almost every zone switches to daylight time on the same March and November Sundays; since 2026 most of western Canada no longer does.

Where are the time zones in the US and Canada?

Each dot is a city coloured by its zone; click one for its current time. Dashed lines are the 15° solar meridians the zones were designed around.

Markers sit at exact city positions. Boundaries follow county lines too fine for this scale, so they are not drawn; see the states on Eastern Time for county detail.

What time is it in each zone right now?

US and Canadian time zones, live (vs ET = difference from Eastern Time now). The three western Canadian rows use fixed offsets, because older time zone data still applies the pre-2026 rules.

What are the eight time zones of North America?

US law (49 CFR Part 71) defines nine zones, including Samoa (UTC−11) and Chamorro (UTC+10) for the Pacific territories, which this map leaves out. Canada's provinces and territories each set their own time by law; they traditionally used six zones, and the 2026 changes in the west are noted below.

Newfoundland Time · NST/NDT · UTC−3:30 / UTC−2:30
The island of Newfoundland and the southeastern corner of Labrador. It is the only half-hour offset in North America, so St. John's is always 1.5 hours ahead of Eastern Time.
Atlantic Time · AST/ADT · UTC−4 / UTC−3
Nova Scotia, New Brunswick, Prince Edward Island and most of Labrador, all with daylight saving. Puerto Rico, the US Virgin Islands and the part of Quebec east of 63°W stay on AST all year.
Eastern Time · EST/EDT · UTC−5 / UTC−4
17 states and Washington D.C. entirely, parts of Florida, Indiana, Kentucky, Michigan and Tennessee, most of Ontario and Quebec, and eastern Nunavut, including Iqaluit. Since November 1, 2026 Manitoba and Ontario west of 90°W also keep UTC−5 all year, so in winter they show Eastern Standard Time. Eastern Time in Canada covers the Canadian side in detail.
Central Time · CST/CDT · UTC−6 / UTC−5
From the Gulf Coast to the Great Plains and Minnesota, plus central Nunavut. In Canada the zone is no longer seasonal: Saskatchewan keeps CST (UTC−6) all year, and Manitoba and Ontario west of 90°W moved to UTC−5 all year on November 1, 2026.
Mountain Time · MST/MDT · UTC−7 / UTC−6
Colorado, Utah, New Mexico, Wyoming, Montana and most of Idaho. Most of Arizona and Yukon use UTC−7 without daylight saving. Alberta and the Northwest Territories have kept UTC−6 ("Alberta Time") all year since November 1, 2026.
Pacific Time · PST/PDT · UTC−8 / UTC−7
California, Washington, most of Nevada and Oregon and the Idaho Panhandle. Most of British Columbia sprang forward in March 2026 and stays on UTC−7, so Vancouver is two hours behind New York in winter and three in summer.
Alaska Time · AKST/AKDT · UTC−9 / UTC−8
Nearly all of Alaska, from Juneau to Anchorage and Fairbanks.
Hawaii–Aleutian Time · HST/HDT · UTC−10 / UTC−9
Hawaii, which never uses daylight time, and the Aleutian Islands west of 169°30′W, which do.

Which places do not use daylight saving time?

  • Arizona stays on MST (UTC−7) all year, which matches Pacific Daylight Time in summer. The Navajo Nation, which extends into Utah and New Mexico, does change its clocks; the Hopi Reservation inside it does not.
  • Hawaii remains on HST (UTC−10) all year.
  • Saskatchewan keeps CST (UTC−6) all year, which matches Mountain Daylight Time in summer.
  • Alberta and the Northwest Territories keep UTC−6 all year from November 1, 2026, so Calgary and Regina now share one clock.
  • Manitoba and Ontario west of 90°W (Kenora, Dryden, Fort Frances, Rainy River) keep UTC−5 all year from November 1, 2026: Toronto's time in winter, an hour behind it in summer.
  • Yukon made UTC−7 permanent in 2020, so Whitehorse matches Pacific Daylight Time in summer and Mountain Standard Time in winter.
  • British Columbia keeps UTC−7 all year since March 2026, as Dawson Creek, Fort St. John, Fort Nelson and Creston already did; a few southeastern areas such as the East Kootenay differ.
  • Puerto Rico, the US Virgin Islands and Quebec's coast east of 63°W keep AST.
  • Atikokan, Ontario and Coral Harbour on Southampton Island keep EST all year; they and the other places on that offset are listed on the UTC−5 page.

Opting out is legal on both sides of the border. Under the US Uniform Time Act of 1966 a state may keep standard time all year but may not adopt permanent daylight time on its own, so states that want year-round summer time must wait for Congress. In Canada the decision belongs to each province or territory, which is how British Columbia, Alberta and Manitoba could each drop the clock change in 2026 without federal approval.

The practical effect is a gap that changes with the season. Phoenix is two hours behind New York in winter and three in summer; Regina and Calgary are one hour behind in winter and two in summer; Winnipeg now matches New York in winter and is one hour behind in summer. Devices with pre-2026 time zone data may still show old times for Vancouver, Calgary and Winnipeg, so the map uses fixed offsets there.

Why don't the zones follow straight lines?

The 1883 railway time system gave each zone a central meridian at a multiple of 15°: 75°W for Eastern, 90°W for Central, 105°W for Mountain, 120°W for Pacific. Those are the dashed lines on the map. Legal boundaries then bent to follow state, county and provincial lines, and over the 20th century many moved west as towns asked to join the zone east of them, usually for business ties and later evening daylight.

The most striking case is Whitehorse. It lies at 135°W, the Alaska meridian, yet keeps UTC−7, so the sun is highest there between about 1:45 and 2:15 PM on the clock, all year. Detroit, at 83°W, sits just west of the Eastern solar band; at the June solstice its solar noon is 1:34 PM EDT. How these lines were drawn, and redrawn county by county, is told on the time zone boundaries page, and the cities on Eastern Time pages show local sunrise and sunset.

Frequently asked questions

How many time zones does Canada have?

Traditionally six, from Newfoundland to Pacific. Since British Columbia, Alberta and Manitoba stopped changing clocks in 2026, the count depends on the season: five different offsets in winter (UTC−3:30 to UTC−7) and six in summer (UTC−2:30 to UTC−7).

What time is it in Hawaii when it is noon in New York?

7:00 AM from November to March, when the gap is 5 hours, and 6:00 AM from March to November, when New York is on daylight time and Hawaii is not.

Which time zone is Puerto Rico in?

Atlantic Standard Time, UTC−4, all year. That is one hour ahead of New York in winter and the same time as New York while the East Coast is on EDT.

Do Alaska and Hawaii change clocks on the same day as New York?

Alaska and the western Aleutians do, at 2:00 AM their own time on the same Sundays. Hawaii stays on UTC−10 all year, so its gap to New York changes twice a year.

Why are some markers outlined in white?

A white ring marks a place that keeps the same offset all year, such as Phoenix, Honolulu, San Juan, Regina, Whitehorse and, since 2026, Vancouver, Calgary and Winnipeg. Their clocks do not move when the US springs forward.
