Content Highlights

  • The United States has six main time zones – Eastern, Central, Mountain, Pacific, Alaska, and Hawaii-Aleutian.
  • Each time zone has its specific time difference from Coordinated Universal Time (UTC).
  • Daylight Saving Time is observed in most states in the United States, starting on the second Sunday of March and ending on the first Sunday of November.

Understanding Time Zones in the USA

Diverse cityscape with clocks showing different time zones.

The USA is divided into several time zones, including the Atlantic Time Zone, Eastern Time Zone, Central Time Zone, Mountain Time Zone, Pacific Time Zone, Alaska Time Zone, and Hawaii-Aleutian Time Zone.

Atlantic Time Zone

The Atlantic Time Zone is part of the United States. It’s not used in every state, but it is important. This time zone falls four hours ahead of Coordinated Universal Time (UTC-4).

People use this term frequently: AST or Atlantic Standard Time. The northeast side of Canada also follows this time zone. Four provinces there live by Atlantic Time.

Eastern Time Zone

The Eastern Time Zone is a key part of the USA. It runs five hours behind Coordinated Universal Time during normal times. Known as Eastern Standard Time, this zone covers many states.

These include Florida, Indiana, Kentucky, Michigan, and Tennessee.

This time zone links to some of the largest cities on the East Coast of Canada and the US. The Eastern Time Zone holds a lot of importance among all zones in America.

Central Time Zone

The Central Time Zone is a big area. It covers parts of Canada, the U.S., Mexico, Central America, and some Caribbean islands. This zone splits its time between Central Standard Time and Central Daylight Time.

The first rules in plain times, while the other plays during daylight saving hours. As part of six zones in the United States, it lies to the west of the Eastern Standard Time Zone’s line.

People often shorten its name to CT or C.

Mountain Time Zone

The Mountain Time Zone is a time zone in the United States seven hours behind Coordinated Universal Time (UTC) during standard time. It covers a large area, roughly a quarter of the continental United States, but surprisingly only has less than 7 percent of the country’s population.

In the past, North Dakota was also part of the Mountain Time Zone, but it switched to Central Time in 2010. The Mountain Time Zone is commonly used in Colorado, Montana, Wyoming, and Utah.

Pacific Time Zone

The Pacific Time Zone is a time zone in the United States. It includes the western part of the continental United States, west of the boundary line between the Mountain and Pacific Time Zones.

In this zone, people use Pacific Standard Time (PST) as their standard time. PST is 8 hours behind Coordinated Universal Time (UTC). The Pacific Time Zone is in effect during standard time in North America.

Alaska Time Zone

The Alaska Time Zone is used in most of Alaska, a big state in the United States. This time zone is 9 hours behind Coordinated Universal Time (UTC – 9 h). This means that when it’s noon in UTC, it will be 3 am in the Alaska Time Zone.

Like other time zones, Alaska observes Daylight Saving Time (DST). During DST, the clocks are adjusted by moving one hour forward. So, if you are in Alaska during DST, it will be UTC – 8 h instead of UTC – 9 h.

It’s interesting to know that different parts of Alaska had separate times before there was an official Alaska Time Zone. But now, almost all of Alaska follows the same time rules.

Hawaii-Aleutian Time Zone

The Hawaii-Aleutian Time Zone is a time zone in the United States. It includes all of Hawaii and parts of Alaska. This time zone is one of six in the country, four hours behind the Eastern Time Zone.

Locally, it’s often called “Hawaiian Time.”.

Daylight Saving Time in the USA

Daylight Saving Time in the USA begins on the second Sunday of March and ends on the first Sunday of November.

History of DST

Daylight Saving Time (DST) has a long history in the United States. It was first used during World War I in 1918 to save energy and use daylight better. But did you know that the idea of DST was proposed by Benjamin Franklin back in 1784? He suggested that people could save candles by waking up earlier to take advantage of the natural sunlight.

However, it wasn’t until 1966, with the Uniform Time Act, DST became widely adopted nationwide. Since then, there have been changes to DST’s start and end dates, creating some confusion for people.

Not all states and territories currently observe DST, with Arizona and Hawaii being two examples. So next time you adjust your clocks forward or backward, remember that this practice has a fascinating history!

DST Start and End Dates

Daylight Saving Time (DST) in the United States follows a specific pattern each year, with the start and end dates usually falling on set Sundays in March and November, respectively. To help you plan accordingly, here’s a handy reference table detailing the start and end dates for DST from 2023 through 2025:

Year DST Start Date DST End Date
2023 March 12 November 5
2024 March 10 November 3
2025 March 9 November 2

Table: Daylight Saving Start and End Dates in the USA

The time officially changes at 2:00 a.m. on these dates. Remember, in most parts of the US, you’ll need to spring forward one hour when DST starts in March and fall back one hour when it ends in November. DST dates are subject to change as some states debate whether to continue observing DST.

States that Observe DST

Most states in the United States observe daylight saving time. Here are the states that observe DST:

  • Alabama
  • Alaska (except for some areas)
  • Arizona (except for the Navajo Nation)
  • Arkansas
  • California
  • Colorado
  • Connecticut
  • Delaware
  • Florida
  • Georgia
  • Idaho (southern part of the state)
  • Illinois
  • Indiana (most of the state, except for a few counties)
  • Iowa
  • Kansas (except for some areas)
  • Kentucky
  • Louisiana
  • Maine
  • Maryland
  • Massachusetts

Time Zone Boundaries in the USA

us time zone map

The time zone boundaries in the USA determine where a one-time zone ends and another begins.

Eastern-Central Boundary

The Eastern-Central Boundary is the line that separates the Eastern Time Zone from the Central Time Zone in the USA. It helps determine the standard time zones in the country. The Eastern Time Zone includes parts of 23 states in the eastern part of America and some areas of eastern Canada, while the Central Time Zone covers several states in the central part of America.

This boundary marks where there is a time difference between these two zones, as they are typically 15 degrees of longitude apart.

Central-Mountain Boundary

The Central-Mountain boundary is an important line that marks the transition between two different time zones in the USA. This boundary separates the Central Time Zone from the Mountain Time Zone.

The Mountain Standard Time Zone includes areas west of this boundary, while most of Kansas follows Central Time. However, four counties on the Colorado border (Sherman, Wallace, Greeley, and Hamilton) observe Mountain Time.

This boundary influences the placement of counties and regions within these time zones. It is a clear marker for when you need to adjust your clocks if you’re traveling between these two time zones.

Mountain-Pacific Boundary

The Mountain-Pacific Boundary is an important part of understanding the time zones in the United States. It marks the boundary between the Mountain Time Zone and the Pacific Time Zone.

This boundary determines the time difference between these two zones and helps people know when to adjust their clocks if they are traveling or communicating with someone in a different time zone.

While there may not be specific information about the exact location or details of this boundary, it plays a significant role in keeping track of time across different regions of the country.
