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 U.S. and Canada. The largest city in the Pacific Time Zone is Los Angeles; the city’s metropolitan area is the largest in this 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,[a] two hours behind the Central Time Zone, three hours behind the Eastern Time Zone, and four hours behind the Atlantic Time Zone.

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.
Effective in the U.S. in 2007 as a result of the Energy Policy Act of 2005, the local time changes from PST to PDT at 02:00 LST to 03:00 LDT on the second Sunday in March and the time returns at 02:00 LDT to 01:00 LST on the first Sunday in November. The Canadian provinces and territories that use daylight time each adopted these dates between October 2005 and February 2007. In Mexico, beginning in 2010, the portion of the country in this time zone uses the extended dates, as do some other parts. The vast majority of Mexico, however, still uses the old dates.
As of 2019, state legislatures in Washington, Oregon, and California were considering a permanent move to daylight savings time.
The meridian 120° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, North America, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole.
The 120th meridian west forms a great circle with the 60th meridian east.
In Canada much of the border between British Columbia and Alberta is defined by the meridian, and in the United States part of the border between California and Nevada approximately follows it.
The mean solar time at this meridian determines the time for the Pacific Time Zone (UTC−08:00) during standard time. Most of the year however, it is the meridian for Alaska Daylight Time, as daylight saving time is observed for nearly 2/3 of the year.Alaska Time Zone
The Alaska Time Zone observes standard time by subtracting nine hours from Coordinated Universal Time (UTC−09:00). During daylight saving time its time offset is eight hours (UTC−08:00). The clock time in this zone is based on mean solar time at the 135th meridian west of the Greenwich Observatory.
The zone includes nearly all of the U.S. state of Alaska and is one hour behind the Pacific Time Zone.
standard time: Alaska Standard Time (AKST)
daylight saving time: Alaska Daylight Time (AKDT)The western Aleutian Islands observe Hawaii–Aleutian Time, one hour behind the remainder of the state.
Effective from 2007, the local time changes from AKST to AKDT at 02:00 LST to 03:00 LDT on the second Sunday in March and returns at 02:00 LDT to 01:00 LST on the first Sunday in November.Alpha, Washington
Alpha is an unincorporated community located in Lewis County, Washington about 3.5 miles away from Cinebar. Due to its rural setting with little settlement concentration, it did not meet qualifications as a Census Designated Place, a program used by the U.S. Census Bureau for unincorporated communities. Alpha appears on the Mayfield Lake U.S. Geological Survey Map. Alpha is located within the Pacific time zone UTC-8. It is the home to the Shoestring Cemetery, located on the Main Avenue, Washington State Route 508.CBS Morning News
CBS Morning News is an American early morning television news program for CBS News that is broadcast on CBS. The program features late-breaking news stories, national weather forecasts and sports highlights. Since 2013, it has been anchored by Anne Marie Green, who concurrently anchored the CBS late-night news program Up to the Minute until its cancellation in September 2015.
The program is broadcast live at 4:00 a.m. Eastern Time (airing in the early timeslot to accommodate CBS stations that start their local morning newscasts at 4:30 a.m.), and is transmitted in a continuous half-hour tape delayed loop until 10:00 a.m. Eastern Time, when CBS This Morning begins in the Pacific Time Zone. The program usually airs as a lead-in to local morning newscasts on most CBS stations, although in the few markets where a morning newscast is not produced by the CBS station, it may air in a two- to three-hour loop immediately before the start of This Morning. The show is updated for any breaking news occurring before 7:00 a.m. Eastern Time, while stations throughout the network will join CBS This Morning in all time zones past that time at their local discretion or network orders for live coverage.Deer Park, California
Deer Park is a census-designated place (CDP) in Napa County, California, United States. The population was 1,267 at the 2010 census. It is part of the Napa, California Metropolitan Statistical Area. Its area code is 707. Its zip code is 94576. It is in the Pacific time zone. Perhaps its best-known attraction is Elmshaven, a large Victorian home lived in by Ellen White in the early twentieth century.Dynamite, Washington
Dynamite is a small unincorporated community in Spokane County, Washington, United States. The elevation of Dynamite is 2,333 feet. Dynamite appears on the Spangle West U.S. Geological Survey Map. Spokane County is in the Pacific Time Zone (UTC-8 hours).Jarbidge, Nevada
Jarbidge is an unincorporated community in Elko County, Nevada, United States. Located at the bottom of the Jarbidge River's canyon near the north end of the Jarbidge Mountains, it lies within the Jarbidge Ranger District of the Humboldt-Toiyabe National Forest and is near the northwest edge of the Jarbidge Wilderness, approximately 10 miles (16 km) south of the Idaho–Nevada border. The ZIP code for Jarbidge is 89826.Jarbidge, along with the rest of Nevada except for the city of West Wendover, is legally in the Pacific Time Zone, but, along with other Idaho border towns such as Jackpot, Mountain City and Owyhee, unofficially observes the Mountain Time Zone due to closer proximity to and greater connections with towns in southern Idaho.Late night television
Late night television is one of the dayparts in television broadcast programming. It follows prime time and precedes the overnight television programming graveyard slot. The slot generally runs from about 11:30 PM to 2:00 AM local time, with variations according to the time zone and broadcaster.
In the United States and Canada, the term is synonymous with the late-night talk show, a type of comedic talk and variety show. Thus, the late night programming block is considered more important in North America. On most major-network stations, a late local newscast airs at the beginning of the block. (This is nearly universal in Canada, as late local news is an easy way to fulfill Canadian content requirements.)
Due to the complications of American and Canadian time zones, live professional sporting matches such as baseball, hockey, and basketball played in Pacific Time Zone and Mountain Time Zone cities, such as Denver, Los Angeles, Phoenix, Portland (Ore.), and Seattle, are often played in the primetime of the Pacific and Mountain Time Zones, but late night in the Central and Eastern time zones, and their lateness often contributes to a perceived bias for eastern teams in sports media.
In the United Kingdom, the late night spot is from 11:00 PM to 12:30 AM and not seen as a priority; ITV and Channel 4 program repeats in the time slot, and the BBC's channels primarily show BBC World News, air movies, or replay documentaries. Similarly, Australian television primarily airs American late shows, lower-priority imported series, or overflows of sports programming in the late night time slot.
On cable television, programming strategies in this time slot include timeshifts of prime time programs and, in the case of children's television channels, signing-off and allowing more adult-oriented fare for the overnight hours under another brand. Two examples are the children's channels Cartoon Network and Nickelodeon, which changes over to Adult Swim and Nick at Nite, respectively, at an hour when most pre-adolescent children go to sleep. Adult Swim and Nick at Nite typically airs series programming, such as reruns of sitcoms, that may have coarser language and more adult themes than Cartoon Network and Nickelodeon.After 11, Japan airs adult talk or variety shows as well as late night anime. This is also true of the United States-based cable channel Cartoon Network, which targets children and young teens during daytime and primetime hours, but changes over to its Adult Swim brand in late-night slots.Mountain Time Zone
The Mountain Time Zone of North America keeps time by subtracting seven hours from Coordinated Universal Time (UTC) when standard time is in effect, and by subtracting six hours during daylight saving time (UTC−06:00). The clock time in this zone is based on the mean solar time at the 105th meridian west of the Greenwich Observatory. In the United States, the exact specification for the location of time zones and the dividing lines between zones is set forth in the Code of Federal Regulations at 49 CFR 71.In the United States and Canada, this time zone is generically called Mountain Time (MT). Specifically, it is Mountain Standard Time (MST) when observing standard time, and Mountain Daylight Time (MDT) when observing daylight saving time. The term refers to how the Rocky Mountains, which range from northwestern Canada to the US state of New Mexico, are located almost entirely in the time zone. In Mexico, this time zone is known as the Zona Pacífico (Pacific Zone). In the US and Canada, the Mountain Time Zone is to the east of the Pacific Time Zone and to the west of the Central Time Zone.
In some areas, starting in 2007, the local time changes from MST to MDT at 2 am MST to 3 am MDT on the second Sunday in March and returns at 2 am MDT to 1 am MST on the first Sunday in November.
Sonora in Mexico and most of Arizona in the United States do not observe daylight saving time, and during the spring, summer, and autumn months they are on the same time as Pacific Daylight Time. The Navajo Nation, most of which lies within Arizona but extends into Utah and New Mexico (which do observe DST), does observe DST, although the Hopi Nation, as well as some Arizona state offices lying within the Navajo Nation, do not.
The largest city in the Mountain Time Zone is Phoenix, Arizona. The Phoenix metropolitan area is the largest metropolitan area in the zone; the next largest metropolitan area that observes Mountain Time is Denver, closely followed by the El Paso–Juárez area.
TV broadcasting in the Mountain Time Zone is typically tape-delayed one hour, so that shows match the broadcast times of the Central Time Zone (i.e. prime time begins at 7 pm MT following the same order of programming as the Central Time Zone).Pala, California
Pala is a small, mostly Native American, community and CDP located in the Pala Indian Reservation, located within San Diego County, California near Fallbrook. For centuries a traditional gathering place of native peoples, it was selected in the early 19th century by Spanish Franciscan missionaries as the site of a mission to serve the Native Americans.
The community is north of Escondido in the San Diego-Carlsbad metro area. In the National Geographic Names Database, it is officially catalogued as feature number 1661174. The community is in ZIP Code 92059, and inside area code 760.
The community name may be derived from the Native American Cupeño or Luiseño language term pal, meaning "water." Another possible origin of the name is the Spanish word pala, which means "shovel."
The community is in the Pacific time zone. Pala is at an altitude of 404 feet, located at latitude 33°21′55″N 117°04′36″W (33.365N, longitude 117.075W).Pony Springs, Nevada
Pony Springs is an unincorporated community in Lincoln County, Nevada, United States. It has an elevation of 6,155 feet and is in the Pacific time zone (UTC−8). Pony Springs is located along U.S. Route 93.Ravensdale, Washington
Ravensdale is a census-designated place (CDP) in King County, Washington, United States. The population was 1,101 at the 2010 census. It is in the Pacific Time Zone. The elevation is 623 feet (190 m).
Based on per capita income, one of the more reliable measures of affluence, Ravensdale ranks 50th of 522 areas in the state of Washington to be ranked.The Comedy Network
The Comedy Network (often shortened to Comedy) is a Canadian English-language specialty channel owned by Bell Media. The channel focuses primarily on sitcoms, comedy films, and stand-up comedy specials. CTV Comedy operates two time-shifted feeds, running on Eastern and Pacific Time Zone schedules.Time in Idaho
The U.S. state of Idaho is covered by two time zones, as described below. All locations observe daylight saving time.
The Pacific Time Zone (UTC−08:00, DST UTC−07:00) covers an area roughly coterminous with the Idaho Panhandle or North Idaho:
Kootenai County (includes Coeur d'Alene)
Latah County (includes Moscow)
Nez Perce County (includes Lewiston)
Portion of Idaho County north of the Salmon River
The towns of Burgdorf and WarrenAn easy way to distinguish the line is that it essentially follows the line that divides Washington and Oregon. If a county in Idaho is due east of Washington, it's Pacific Time. On the other hand, the counties of Idaho that are fully due east of Oregon are on Mountain Time.
The Mountain Time Zone (UTC−07:00, DST UTC−06:00) covers the rest of the state.Time in Oregon
Time in Oregon is divided into two zones. The vast majority of the state is contained in the Pacific Time Zone. Most of sparsely populated Malheur County, including its largest city, Ontario, and its county seat, Vale, are in the Mountain Time Zone due to their proximity to Boise, Idaho. The time zone division occurs at the southwest corner of township 35 S, range 37 E (approximately 42.45 degrees north latitude), continuing east to the state line, then south along the Oregon-Idaho border to the Nevada state line.Drewsey in Harney County is officially in the Pacific Time Zone, but some residents unofficially observe Mountain Time due to proximity to Malheur County. Local businesses strictly enforce the practice of Pacific Time, however.W Network
W Network (often shortened to W) is a Canadian specialty television channel. Owned by Corus Entertainment, it broadcasts general entertainment programming oriented towards a female audience. Since 2018, W Network has been the exclusive home to original series and made-for-TV movies from Hallmark Channel and its sister networks.
W Network was originally established in 1995 as the Women's Television Network (WTN), which had a focus on women's lifestyle programming. The channel was eventually acquired by Corus in 2001 and relaunched under its current branding in 2002. As part of the relaunch, W's programming shifted to a mix of both entertainment and lifestyle programming. This lasted until 2017, when the majority of its lifestyle programming was dropped and moved to other networks.
The channel is available in two time shifted feeds, East (operating from the Eastern Time Zone) and West (operating from the Pacific Time Zone).Wheatland, Oregon
Wheatland is an unincorporated community in Yamhill County, Oregon, United States. It is near the Willamette River where the Wheatland Ferry takes traffic across the river into Marion County. Its elevation is 118 feet (36 m); it is in the Pacific Time Zone.
