The Alaska Standard Time Zone (AKST) is a geographic region that keeps time by subtracting nine hours from Coordinated Universal Time (UTC).

It includes all of the U.S. state of Alaska, except for the Aleutian Islands west of 169° 30′ west. The western Aleutians observe Hawaii-Aleutian Time, one hour behind the remainder of the state.
