UTC time

Alaska Standard Time (AKST) is the time zone for most of the state of Alaska, except for the Aleutian Islands. AKST operates at UTC-9:00, meaning it is 9 hours behind Coordinated Universal Time (UTC).

AKST is observed across most of Alaska, including major cities such as Anchorage, Juneau, and Fairbanks. The western Aleutian Islands use Hawaii-Aleutian Standard Time (HAST).

Alaska observes Daylight Saving Time. During the summer months, Alaska switches to Alaska Daylight Time (AKDT), which is UTC-8:00, one hour ahead of AKST.

New York (EST/EDT): AKST is 4 hours behind Eastern Standard Time (EST, UTC-5:00) and 5 hours behind Eastern Daylight Time (EDT, UTC-4:00).

London (GMT/BST): AKST is 9 hours behind Greenwich Mean Time (GMT, UTC+0) and 10 hours behind British Summer Time (BST, UTC+1).

Tokyo (JST): AKST is 18 hours behind Japan Standard Time (JST, UTC+9:00).

Sydney (AEST/AEDT): AKST is 19 hours behind Australian Eastern Standard Time (AEST, UTC+10:00) and 20 hours behind Australian Eastern Daylight Time (AEDT, UTC+11:00).

Alaska is located far to the west of the contiguous United States and spans a large geographic area. Its unique time zone (AKST) accommodates its location and ensures that local time better aligns with the daylight hours across the state.

No other countries observe AKST. However, parts of French Polynesia, in the South Pacific, observe UTC-9:00, which is the same as AKST.
