How many time zones are in the USA? In the continental United States, there are four time zones, while Alaska and Hawaii have their own respective time zones. Therefore, there are a total of six time zones in the USA. Additionally, there are three time zones for unincorporated territories: Puerto Rico and the U.S. Virgin Islands (AST), American Samoa (SST), and Guam and the Northern Mariana Islands (ChST).

What Time Is It in America?

To calculate the current time in the USA, you need to know the difference from Coordinated Universal Time (UTC). You can simply refer to the map above.

Example: If it is 8:00 PM in London, and Los Angeles is in the Pacific Time Zone (typically 8 hours behind London), you simply subtract 8 hours to find that the time in Los Angeles is exactly noon.

Daylight Saving Time in the USA

Daylight Saving Time in the USA begins in March when clocks are moved forward from 2:00 AM to 3:00 AM. In the fall, they are turned back from 2:00 AM to 1:00 AM. Daylight Saving Time is observed across the United States, with the notable exceptions of Hawaii and most of Arizona.

Overview of U.S. Time Zones

Time zones in the United States do not always follow state boundaries. For instance, North Dakota, South Dakota, and Kansas span two time zones.

1. 

   Eastern Standard Time

   • Eastern Standard Time: EST, UTC-5
   • Eastern Daylight Time: EDT, UTC-4 (observed from March to November)

   The Eastern Time Zone is located on the East Coast of the USA and fully covers 17 states. Indiana, Kentucky, Michigan, and Tennessee are split between Eastern and Central time. A portion of Florida, west of the Apalachicola River, also follows Central Time.

   🔴 U.S. States in the Eastern Time Zone

   Connecticut, Delaware, Florida (except for the area west of the Apalachicola River), Georgia, Indiana (except for some counties near Chicago and Evansville), South Carolina, Kentucky (only the eastern half), Maine, Maryland, Massachusetts, Michigan (except for four counties in the northwest), New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, North Carolina, Tennessee (eastern third), Virginia, Washington D.C., West Virginia

2. 

   Central Standard Time

   • Central Standard Time: CST, UTC-6
   • Central Daylight Time: CDT, UTC-5 (observed from March to November)

   The Central Time Zone is the second most populous after the Eastern Time Zone. It encompasses 20 states, although some fall only partially within this zone.

   🟡 U.S. States in the Central Time Zone

   Alabama, Arkansas, Florida (only the part west of the Apalachicola River), Illinois, Indiana (only a few counties near Chicago and Evansville), Iowa, South Dakota (only the eastern half, east of the Missouri River), Kansas (except for four counties near the Colorado border), Kentucky (western half of the state), Louisiana, Michigan (only four counties in the northwest), Minnesota, Mississippi, Missouri, Nebraska (the eastern two-thirds), Oklahoma, North Dakota (except for the southwest corner), Tennessee (only the western two-thirds), Texas (except for Hudspeth and El Paso counties in the west), Wisconsin

   • Mountain Daylight Time: MDT, UTC-6 (observed from March to November)

   The Mountain Time Zone is named after the Rocky Mountains, which cover most of the region. It is important to note that most of Arizona does not observe Daylight Saving Time; therefore, from March to November, the time in Arizona is identical to that of the Pacific Time Zone (West Coast). The area is marked in darker green on the map.

   🟢 U.S. States in the Mountain Time Zone

   Arizona (except for the Navajo Nation, which observes Daylight Saving Time), Colorado, Idaho (the southern half, south of the Salmon River), South Dakota (only the western half), Kansas (Greeley, Hamilton, Sherman, and Wallace counties in the west), Montana, Nebraska (only the western third), New Mexico, Utah, Wyoming, North Dakota (only the southwest corner near the Missouri River), Texas (only El Paso and Hudspeth counties in the west).
