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

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.
