Time in Alaska
Time zones
Alaska is covered by three time zones, as described below:
- Islands west of -169.5° (169°30'W) are in the Hawaii-Aleutian Time Zone (UTC−10:00, DST UTC−09:00). Daylight saving time (DST) is observed.
- Annette Island, home to the Metlakatla Indian Community, is in the Pacific Time Zone (UTC−08:00) and does not observe DST.[1]
- The town of Hyder, because it essentially is a single town split by the US-Canada border, unofficially observes Pacific Time including DST (UTC−08:00, DST UTC−07:00) like its neighbor Stewart, British Columbia, with the exception of the U.S. Post Office (because it is a federal facility).[1]
- The rest of the state is in the Alaska Time Zone and observes DST (UTC−09:00, DST UTC−08:00).
tz database
The tz database version 2014b contains seven time zones for Alaska for historical reasons. Only three (America/Adak, America/Anchorage, and America/Metlakatla) are currently necessary.
