USA Time Zone Map

The USA Time Zone Map features nine standard Time Zones. This includes Atlantic Standard Time, Eastern Standard Time, Central Standard Time, Mountain Standard Time, Pacific Standard Time, Alaska Standard Time, Hawaii-Aleutian Standard Time, Samoa Standard Time, and Chamorro Standard Time.

In each of these Time Zones, standard time consists of an integral number of hours offset by the Coordinated Universal Time (UTC) time scale. The U.S. Naval Observatory maintains UTC using multiple accurate ‘atomic clocks’ at laboratories around the globe.

What Time is it in The USA?

To compute the current time in the United States, the difference between the zero meridian and your location must be known. Simply view the map above. Germany or the Netherlands are located in the UTC+1 time zone, so subtract one hour from the current time.

You subtract 9 hours to determine that it is now 11 a.m. in Los Angeles.

USA Time Zone Map

By law, the United States of America is divided into nine standard time zones covering the states, territories, and other U.S. possessions, with the majority of the country observing daylight saving time during the spring, summer, and autumn. The Department of Transportation administers the time zone boundaries and daylight saving time rules.

Two federal agencies provide official and exceedingly accurate timekeeping services (clocks): NIST (the National Institute of Standards and Technology; a Department of Commerce agency) and UNSO (the United States Naval Observatory). The timepieces managed by these services are synchronized with one another and with those managed by other internationally recognized timekeeping organizations.

Daylight Saving Time in The USA

Daylight Saving Time” is abbreviated with a D in the midsection (for instance, EDT). March begins Daylight Saving Time when the timepiece at 2:00 a.m. advances to 3:00 a.m. It returns in the autumn from 2:00 to 1:00. In the United States, daylight saving time is observed nationwide with the exception of Hawaii and a large portion of Arizona.

Daylight saving time is observed between Sunday, March 11, 2018 (1 hour forward) and Sunday, November 4, 2018 (1 hour backward). At 2 am on the first Sunday of November, time zones that observe daylight saving time return to standard time. Eastern daylight time (EDT) replaces Eastern standard time (EST).

A broad energy bill (Energy policy act of 2005) signed into law on August 8, 2005, by President George W. Bush increased daylight saving time by four weeks commencing in 2007. The provisions of the bill stipulated that daylight saving time would begin on the first Sunday in April and conclude on the last Sunday in October. The regulation became effective on March 11, 2007.

According to the polls, the majority of respondents supported extending daylight saving time, while some opponents fought against the extension. According to the airline industry, changing schedules would cost millions of dollars, and some school systems were concerned that students would have to wait for the bus in the dark in the mornings.

How to Use The Map?

  • Search for any city in the above search bar and position a black ‘pin’ Pinby that city on the map. If you position multiple pins, an additional line of information with links to those cities’ pages is added beneath the map. You may add as many bookmarks as you like.
  • To permanently eliminate the pins (undo is not an option), click here or on the Time Zone Map link in the menu above.
  • When you hover your mouse over one of the red marks, the city, country, and current local time will appear.
  • “DST” is displayed if Daylight Saving Time is currently in effect.
  • Clicking on any red dot will take you to a page with information about that city’s time, weather, sunrise/sunset, moon phases, and much more.
  • When you hover your cursor over the map, time zones are highlighted.
    (Not supported in IE versions IE8 and earlier.)
  • Find the current time offset from Coordinated Universal Time (UTC), displayed only in whole hours, at the bottom of the map. UTC deviations in areas with diagonal stripes are not whole hours.

Current Date And Times Across USA

The United States of America is currently observing Daylight Savings Time. The majority of Arizona and Hawaii do not observe Daylight Saving Time. Arizona’s summertime is identical to Pacific Daylight Time (PDT). Arizona observes Mountain Standard Time (MST) during the winter.

Alaska (AK) 90% of Alaska is one hour behind Pacific Time, while the Aleutian Islands are on Hawaii-Aleutian time. Important (current time) Exceptions: There are portions of Florida, Idaho, Indiana, Kansas, Kentucky, Michigan, Nebraska, North Dakota, Oregon, South Dakota, Tennessee, and Texas that span two time zones.

Difference Between GMT and USA Time Zones

Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, and the state of Arizona do not observe Daylight Saving Time for the United States and its territories (unlike the Navajo Indian Reservation, which does observe DST). Due to its size and location within three states, the Navajo Nation observes Daylight Saving Time.


The USA Time Zone Map serves as a valuable tool for understanding the time differences across the United States. It visually illustrates the various time zones that span the country, helping individuals navigate and coordinate activities across different regions.

The map highlights the boundaries and names of each time zone, providing a clear overview of the time variations from coast to coast. Whether for travel, business, or simply staying connected with friends and family across different states, the USA Time Zone Map is a helpful resource for effectively managing time-related matters within the United States.
