How many time zones are there in the USA? In the continental United States, there are four time zones, with Alaska and Hawaii having their own respective time zones. Therefore, there are a total of six time zones in the USA, with three additional 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 must know the difference from Coordinated Universal Time (UTC). Simply refer to the map above.

Example: In London, it is 8:00 PM, and Los Angeles is in the PST/PDT -8 time zone. Subtract 8 hours, and you will find that the time in Los Angeles is exactly noon.

Overview of U.S. Time Zones

The time zones in the United States do not always correspond to state boundaries. For example, North Dakota, South Dakota, and Kansas fall into two time zones simultaneously.

1. 

   Eastern Standard Time

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

   The EST/EDT time zone is located on the eastern coast of the USA and fully covers 17 states. Indiana, Kentucky, Michigan, and Tennessee are also part of CST/CDT. A portion of Florida, west of the Apalachicola River, also follows CST/CDT.

   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
