List of Time Offsets by U.S. State and Territory provides an overview of the time zones used by states and territories in the United States. The United States is divided into several time zones, ranging from the Eastern Standard Time (EST) to the Hawaii-Aleutian Standard Time (HAST). This article lists the standard time offsets from Coordinated Universal Time (UTC) for each state and territory.

Overview

The United States spans nine standard time zones and observes Daylight Saving Time (DST) in many areas, which shifts the clock forward by one hour during the warmer months. The time zones are defined by the United States Code, specifically in the Uniform Time Act. This diversity in time zones is due to the country's vast geographical size, stretching from the Atlantic to the Pacific.
