List of time offsets by U.S. state and territory

From Wikipedia, the free encyclopedia

Map of U.S. time zones with new CST and EST areas displayed. Some U.S. time zones, such as the Samoa Time Zone, are not on this map.

This is a list of the time offsets by U.S. states, federal district, and territories. For more about the time zones of the U.S. see time in the United States.

Most states are entirely contained within one time zone. However, some states are in two time zones, due to geographical, socio-political or economic reasons.
