USA Time Zone Map

The United States of America observes nine standard Time Zones. These are, Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaska Standard Time (AKST), Hawaii-Aleutian Standard Time (HAST), Samoa Standard Time, and Chamorro Standard Time. Within each of these Time Zones, standard time consists of an integral set of hours offset by a time scale known as the Coordinated Universal Time (UTC). UTC is maintained by multiple and accurate 'atomic clocks' at laboratories all over the world, comprising the U.S. Naval Observatory.

Most states observe daylight saving time during the summer months, which moves the clocks forward one hour, enabling the population to make better use of daylight. Daylight saving time begins on the second Sunday in March and ends the first Sunday of November. Arizona and Hawaii do not observe daylight savings time, instead opting to use standard time throughout the entire year in their Time Zones. Because of this, Arizona is part of the Pacific Time Zone part of the year, and the Mountain Time Zone for the rest of the year. However, the Navajo Nation, located within Arizona, does observe daylight saving time, and the Hopi Nation, inside the Navajo Nation, does not observe daylight saving time.


As shown on the US Time Zones Map, time zones do not always follow state lines, though most states are situated fully in one Time Zone or another. States near the edge of one of the Time Zones are sometimes divided into two Time Zones. States that are split between two Time Zones include Kentucky, Tennessee, North and South Dakota, Nebraska, and Idaho. Small portions of other states are also separated from the rest of their state in terms of Time Zones as depicted on the USA Time Zones Map.
