Time in the United States is governed by a single time zone, which is the Coordinated Universal Time (UTC) zone. The United States is divided into six time zones: Pacific, Mountain, Central, Eastern, Alaska, and Hawaii. Each time zone is represented by a unique offset from UTC, ranging from UTC-5 to UTC+12.
The time zones are based on the mean solar time at a specific meridian, with the time zone boundaries being the meridians at 75°, 90°, 105°, 120°, 135°, and 150° west longitude.
