Eastern Time Zone

The Eastern Time Zone (ET) is a time zone encompassing part or all of 22 states in the eastern part of the contiguous United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama in Central America, and the Caribbean Islands.

Places that use Eastern Standard Time (EST) when observing standard time (autumn/winter) are 5 hours behind Coordinated Universal Time (UTC−05:00).

Eastern Daylight Time (EDT), when observing daylight saving time DST (spring/summer) is 4 hours behind Coordinated Universal Time (UTC−04:00).

In the northern parts of the time zone, on the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour "gap". On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving time.

History

The boundaries of the Eastern Time Zone have moved westward since the Interstate Commerce Commission took over time-zone management from railroads in 1938. For example, the easternmost and northernmost counties in Kentucky were added to the zone in the 1940s, and in 1961 most of the state went Eastern. In 2000, Wayne County, on the Tennessee border, switched from Central to Eastern.[1] In March 2018, the Florida Legislature passed a bill requesting authorization from Congress for year-round daylight savings time, which would effectively put Florida on Atlantic Standard Time year-round (except for west of the Apalachicola River, which would be on Eastern Standard Time year-round).[2]

Daylight Saving Time

The Uniform Time Act of 1966 ruled that daylight saving time would run from the last Sunday of April until the last Sunday in October in the United States.[3] The act was amended to make the first Sunday in April the beginning of daylight saving time as of 1987.[3] The Energy Policy Act of 2005 extended daylight saving time in the United States beginning in 2007. So local times change at 2:00 a.m. EST to 3:00 a.m. EDT on the second Sunday in March and return at 2:00 a.m. EDT to 1:00 a.m. EST on the first Sunday in November.[3] In Canada, the time changes as it does in the United States.[4][5]

Canada

In Canada, the following provinces and territories are part of the Eastern Time Zone:

All observe Daylight Saving Time in sync with the United States, with very localized exceptions.

United States

The boundary between time zones is set forth in the Code of Federal Regulations, with the boundary between the Eastern and Central Time Zones being specifically detailed at 49 CFR 71.[6]

Seventeen states and Washington, D.C. are located entirely within the Eastern Time Zone. They are:

Five states are partly in the Eastern Time Zone, with the remaining portions in the Central Time Zone. They are:

Eastern Time is also used somewhat as a de facto official time for all of the United States because it includes the capital city (Washington D.C.), the most populous city (New York City), and half of the country's population. For this reason, media organizations will often report when events happened or are scheduled to happen in Eastern Time even if they occurred in another time zone, and TV schedules are also almost always posted in Eastern Time. In the United States, all nationally televised morning programs (except Good Morning America Weekend Edition which some ABC affiliates on the east coast air on a tape-delay), some daytime talk shows, evening newscasts, most talent and awards shows, and any other nationally televised event that airs live on American television during prime time and on the weekends (such as sports television) are broadcast live in the Eastern Time Zone. Major professional sports leagues also post all game times in Eastern time, even if both teams are from the same time zone, outside of Eastern Time. For example, a game time between two teams from Pacific Time Zone will still be posted in Eastern time (for example, one may see "Seattle at Los Angeles" with "10:00 p.m." posted as the start time for the game, often without even clarifying the time is posted in Eastern time).

Most cable television and national broadcast networks advertise airing times in Eastern time. National broadcast networks (ABC, CBS, The CW, FOX, NBC) generally have two primary feeds, an eastern feed for Eastern and Central time zones, and a tape-delayed western feed for the Pacific Time Zone. The prime time is set on Eastern and Pacific at 8:00 p.m., with the Central time zone stations receiving the eastern feed at 7:00 p.m. local time. Mountain Time Zone stations receive a separate feed at 7:00 p.m. local time. As Arizona does not observe daylight saving time, during the summer months, it has its own feed at 7:00 p.m. local time. Cable channels with a separate western feed (such as HBO, whose western feed is called "HBOW") generally air the same programming as the eastern feed delayed by three hours. Other cable networks such as the Discovery family of networks repeat their prime time programming three hours later; this allows for the same show to be advertised as airing at "8:00 p.m. E/P" (that is, "8:00 p.m. Eastern and Pacific time"). Networks specializing in the airing of sports events, such as ESPN, advertise all of their programming in Eastern and Pacific, incorporating the 3-hour time difference (as in "8:00 p.m. Eastern/5:00 p.m. Pacific") and leaving viewers in the remaining time zones to calculate start time in their own areas.

Mexico

  • Quintana Roo: This is the only Mexican state to observe EST. It moved from Central Time to Eastern Time after a successful lobbying effort by tourism interests.[8]

Caribbean Islands

The Bahamas officially observe both Eastern Standard Time during the winter months and Eastern Daylight Time during the summer months. Cuba generally follows the U.S. with Eastern Standard Time in the winter, and Eastern Daylight Time in the summer, but the exact day of change varies year to year. Cayman Islands and Jamaica use Eastern Standard Time year-round.

Turks and Caicos Islands

The Turks and Caicos Islands followed eastern time with daylight saving until 2015, when the territory switched to the Atlantic Time Zone. The Turks and Caicos Islands switched back to the pre-2015 schedule in March 2018.[9] A 2017 consultation paper highlighted being in the same time zone as the eastern U.S., for business and tourism, as an important factor in the decision.[10]

Central and South America

The Central American countries from Guatemala to Costa Rica use Central Standard Time UTC−06:00 year-round.

Panama in Central America uses Eastern Standard Time UTC−05:00 year-round.

The state of Acre and the southwest part of the state of Amazonas (both in Brazil), along with Colombia, Ecuador (except for the Galápagos Islands, which uses Central Standard Time), and Peru in South America also use EST year-round.

75th meridian west

The meridian 75° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, North America, the Atlantic Ocean, the Caribbean Sea, South America, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole.

The mean solar time of this meridian is the base for the Eastern Time Zone (UTC-5 during standard time).

Stations belonging to the US National Weather Service begin submitting weather reports when the mean solar time of this meridian is 8:00 am. Report collection ends 30–40 minutes later and the data is used to create the day's weather forecast.The 75th meridian west forms a great circle with the 105th meridian east.

Area code 906

Area code 906 is the telephone area code for the entire Upper Peninsula of Michigan, including the following cities:

Baraga

Calumet

Escanaba

Gladstone

Hancock

Houghton

Iron Mountain

Ironwood

Ishpeming

L'Anse

Marquette

Manistique

Menominee

Newberry

Norway

St. Ignace

Sault Ste. Marie (its namesake in Ontario uses area code 705)Isle Royale National Park and Mackinac Island also use the 906 area code.

Area code 906 is in the Eastern Time Zone, except for the counties bordering Wisconsin, which are in the Central Time Zone.

It’s one of the few area codes with a 0 as its middle digit that doesn’t cover the entire state (or didn’t at the time it was created).

CBS This Morning

CBS This Morning is an American morning television program that is broadcast on CBS. The program, which shares its title with a more traditionally formatted morning program that aired on the network from 1987-1999, airs Monday-Saturday. It airs live from 7:00 a.m. - 9:00 a.m. in the Eastern Time Zone. On weekdays, it airs on tape-delay in the Central and Mountain Time Zones; stations in the Pacific Time Zone receive an updated feed with a specialized opening and updated live reports. Stations outside the Eastern Time Zone carry the Saturday broadcast at varied times. It is the tenth distinct morning news-features program format that CBS has aired since 1954, having replaced The Early Show on January 9, 2012.

The program emphasizes general national and international news stories and in-depth reports throughout each edition, although it also includes live in-studio and pre-taped interviews. The format was chosen as an alternative to the soft news and lifestyle-driven formats of competitors Today and Good Morning America following the first hour or half-hour of those broadcasts, in an attempt to give the program a competitive edge with its hard news format. (CBS has historically placed third in the ratings among the network morning shows.)

Central Time Zone

The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean.

Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer most of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC.

Central United States

The Central United States is sometimes conceived as between the Eastern and Western United States as part of a three-region model, roughly coincident with the U.S. Census' definition of the Midwestern United States plus the western and central portions of the U.S. Census' definition of the Southern United States. The Central States are typically considered to consist of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Wisconsin, and Illinois. Sometimes Indiana, Ohio, Kentucky, Tennessee, West Virginia, Mississippi, and Alabama are also considered to be central states.

4 of 9 Census Bureau Divisions have names containing "Central", though they are not grouped as a region. They include 20 states and 39.45% of the US population as of July 1, 2007.Almost all of the area is in the Gulf of Mexico drainage basin, and most of that is in the Mississippi Basin. Small areas near the Great Lakes drain into the Great Lakes and eventually the St. Lawrence River; the Red River Basin is centered on the North Dakota-Minnesota border and drains to Hudson Bay.

The Central Time Zone is the same area plus the Florida Panhandle, minus Ohio, most of Michigan, most of Indiana, westernmost fringes of Great Plains states, eastern and northern Kentucky, eastern Tennessee, and El Paso, Texas.

Floods have been a problem for the region during the 20th and early-21st century.

Chamorro Time Zone

The Chamorro Time Zone, formerly the Guam Time Zone, is a United States time zone which observes standard time ten hours ahead of Coordinated Universal Time (UTC+10:00). The clock time in this zone is based on the mean solar time of the 150th meridian east of the Greenwich Observatory.

The zone includes the U.S. territories of Guam and the Northern Mariana Islands, where the Chamorro people are the original inhabitants. Since Daylight Saving Time (DST) is not observed anywhere in this zone, the time is always known as Chamorro Standard Time (ChST).

The zone is two hours behind Wake Island Time Zone and 15 hours ahead of North American Eastern Time Zone.

Chamorro Standard Time shares the same time as Australian Eastern Standard Time.

Glen Jean, West Virginia

Glen Jean is a census-designated place (CDP) in Fayette County, West Virginia, United States, near Oak Hill. As of the 2010 census, its population is 210.The area had been known was White Oaks, but when the town was founded in the early 1870s the community was named for Jean McKell, the wife of landowner Thomas G. McKell. The town was a center for the coal mining industry and a railroad junction, formerly boasting an opera house, hotels and a company store. Much of the town has disappeared since the end of the coal boom. The chief remaining structure is the Bank of Glen Jean, listed on the National Register of Historic Places.

National League West

The National League West is one of the three divisions of the National League of Major League Baseball in North America (including Canada). This Division was formed for the 1969 season when the National League expanded to 12 teams by adding the San Diego Padres and the Montreal Expos. For purpose of keeping a regular-season of 162 games, half of the teams were put into the new East Division and half into the new West Division. Within each division, the teams played 18 games each against their five division mates (90 games), and also 12 games against the teams in the opposite division (72 games), totaling 162 games.

Despite the geography, the owners of the Chicago Cubs insisted that their team be placed into the East Division along with the teams in New York City, Philadelphia, and Pittsburgh. Also, the owners of the St. Louis Cardinals wanted that team to be in the same division with their natural rivals of the Cubs. The league could have insisted on a geographical alignment like the American League did. But the owners were also concerned about what they thought would be a large imbalance in the strength of the divisions. In the previous two seasons prior to realignment, the Cardinals, Giants, and Cubs finished 1-2-3 in the National League standings. The owners were concerned about putting those teams in the same division, thereby creating one very strong division (West) and one weak one (East). Given all of this, the owners of the Atlanta Braves and the Cincinnati Reds consented to being placed into the West Division, even though Atlanta and Cincinnati are both in the Eastern Time Zone. Hence, the West Division had teams spread all the way from the East to the Pacific Coast, and scattered over four time zones. The East Division was spread over the Eastern Time Zone and the Central Time Zone - despite the fact that the National League had six teams in the Eastern Time Zone and six teams spread between the Central Time Zone and the Pacific Time Zone.

All of this increased the traveling distances and times for all of the teams, and it also made radio broadcasting and TV broadcasts of the games more difficult to schedule. The Braves and the Reds had to travel all the way to California three times during each baseball season, and the three teams in California had to travel to Atlanta, Cincinnati, and Houston three times also. Sometimes, the trouble could be alleviated for them by playing some games in Chicago, St. Louis, or Pittsburgh on the same long road trips. The 1994 addition of the Central Division would completely remedy these problems, when the Reds and Braves moved to the NL Central and NL East respectively.

Pacific Time Zone

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, two hours behind the Central Time Zone, three hours behind the Eastern Time Zone, and four hours behind the Atlantic Time Zone.

Smith Beach, Virginia

Smith Beach is an unincorporated community in Northampton County, Virginia, United States. The elevation is 20 feet (6 m). Smith Beach appears on the Cheriton U.S. Geological Survey Map. Northampton County is in the Eastern Time Zone (UTC -5 hours).

Time in Indiana

The U.S. state of Indiana is divided between Eastern and Central time zones. The official dividing line has generally moved progressively west from its original location on the Indiana–Ohio border, to a position dividing Indiana down the middle, and finally to its current location along much of the Indiana–Illinois border. In April 2006, several southwestern and northwestern counties reverted to Central time, although by late 2007 all but two had returned to Eastern time.

As Indiana is on the western frontier of the Eastern time zone, there was opposition from many in the state to observing daylight saving time for decades. The 2005 decision by the Indiana General Assembly to implement daylight saving time state-wide beginning in April 2006 remains controversial.

Yatesboro, Pennsylvania

Yatesboro is an unincorporated community located in Cowanshannock Township, Armstrong County, Pennsylvania. The community is located 1.0 mile (1.6 km) west of Rural Valley. Yatesboro has a post office with ZIP code 16263.

The elevation is 1,132 feet. Yatesboro appears on the Rural Valley U.S. Geological Survey Map. Armstrong County is in the Eastern Time Zone (UTC -5 hours).
