The Pacific Time Zone (PT) is a time zone encompassing parts of western Canada, the western United States, and western Mexico. Places in this zone observe standard time by subtracting eight hours from Coordinated Universal Time (UTC−08:00). During daylight saving time, a time offset of UTC−07:00 is used.

In the United States and Canada, this time zone is generically called the Pacific Time Zone. Specifically, time in this zone is referred to as Pacific Standard Time (PST) when standard time is being observed (early November to mid-March), and Pacific Daylight Time (PDT) when daylight saving time (mid-March to early November) is being observed. In Mexico, the corresponding time zone is known as the Zona Noroeste (Northwest Zone) and observes the same daylight saving schedule as the United States and Canada. The largest city in the Pacific Time Zone is Los Angeles, whose metropolitan area is also the largest in the time zone.

The zone is two hours ahead of the Hawaii–Aleutian Time Zone, one hour ahead of the Alaska Time Zone, one hour behind the Mountain Time Zone,{{efn|While the state of Arizona lies entirely within the Mountain Time Zone, daylight saving time is only observed within the Navajo Nation; as a result, most of Arizona is aligned with the Pacific Time Zone from mid-March to early November.}} two hours behind the Central Time Zone, three hours behind the Eastern Time Zone, and four hours behind the Atlantic Time Zone.

Canada

One Canadian province is split between the Pacific Time Zone and the Mountain Time Zone:

British Columbia – all, except for the Highway 95 corridor (including Golden and Creston) in the southeast, and Tumbler Ridge, Fort St. John, and Dawson Creek in the northeast

The border between time zones in British Columbia was decided in a 1972 plebiscite held in northeastern and southeastern electoral districts due to their ties to neighboring Alberta.{{cite news |last=Palmer |first=Vaughn |date=March 20, 2019 |title=Pushing to make daylight time permanent without ticking off the masses |url=https://vancouversun.com/opinion/columnists/vaughn-palmer-pushing-to-make-daylight-time-permanent-without-ticking-off-the-masses |work=Vancouver Sun |access-date=June 28, 2023}}

As of September 24, 2020, Yukon officially switched from the Pacific Time Zone to a time zone "to be reckoned as seven hours behind Coordinated Universal Time (UTC−7)" after deciding to stop observing daylight saving time.{{cite news |last1=Howells |first1=Laura |title=How do you stop a time change?

Daylight saving time

Through 2006, the local time (PST, UTC−08:00) changed to daylight time (PDT, UTC−07:00) at 02:00 LST (local standard time) to 03:00 LDT (local daylight time) on the first Sunday in April, and returned at 02:00 LDT to 01:00 LST on the last Sunday in October.{{cite news |last=Sherwood |first=Courtney |date=March 7, 2007 |title=Daylight-saving time's early arrival may vex computers |page=A1 |work=The Columbian |url=https://www.newspapers.com/article/the-columbian-daylight-saving-times-ear/127289551/ |via=Newspapers.com |access-date=June 28, 2023}} The United States Congress passed the Energy Policy Act of 2005, which moved the local time changes from PST to PDT to the second Sunday in March and the reversal from PDT to PST to the first Sunday in November. Like other Canadian provinces that observe daylight time, British Columbia adopted the same dates in April 2006, to take effect in March 2007 alongside the U.S.{{cite news |date=April 2, 2006 |title=Daylight savings time changes next year |page=A2 |work=The Province |agency=The Canadian Press |url=https://www.newspapers.com/article/the-province-daylight-savings-time-chang/127289673/ |via=Newspapers.com |access-date=June 28, 2023}} Several Mexican states, including Baja California, implemented the new dates for the daylight time changes in 2010, ending a three-year period where cities across the Mexico–United States border had a one-hour difference for two months a year.{{cite news |date=November 5, 2010 |title=Sunday time change will put San Diego, Tijuana on same clock |url=https://www.lajollalight.com/sdljl-sunday-time-change-will-put-san-diego-tijuana-on-2010nov05-story.html |work=La Jolla Light |agency=City News Service |access-date=June 28, 2023}}

Proposals to abolish the bi-annual time change and adopt year-round standard time or daylight time gained popularity among U.S. states in the 2010s. 59 percent of voters in California approved a 2018 ballot proposition that authorizes the legislature to use year-round daylight saving time, pending Congressional approval.{{cite news |last=Nixon |first=Nicole |date=March 11, 2022 |title=New bill could have California voters weigh in on daylight saving time — again |url=https://www.capradio.org/articles/2022/03/11/new-bill-could-have-california-voters-weigh-in-on-daylight-saving-time-again/ |publisher=CapRadio |location=Sacramento |access-date=June 28, 2023}} The Washington State Legislature passed a bill in May 2019 that would move the state to permanent daylight time, subject to Congressional approval;{{cite news |last=Clarridge |first=Christine |date=May 8, 2019 |title=Inslee signs bill to make daylight saving time permanent in Washington; next step Congress |url=https://www.seattletimes.com/seattle-news/politics/gov-inslee-expected-to-sign-bill-bringing-state-closer-to-permanent-daylight-saving-time/ |work=The Seattle Times |access-date=June 28, 2023}} the Oregon Legislative Assembly passed a similar bill a month later, while California's attempt failed.{{cite news |last=Cuthill |first=Meagan |date=November 4, 2022 |title=Yes, we're still changing the clocks.
