Most of the state is in the Alaska Time Zone, but the western Aleutian Islands are in the Hawaii-Aleutian Time Zone. Uniquely, there’s also one very small town in Alaska called Hyder which observes Pacific Time (PT) because it's right on the Canadian border and has more links with Canada than it does with the rest of Alaska or the US in general.
Alaska Time Zone
The vast majority of the state of Alaska is in the Alaska Time Zone, shortened to AKT. This time zone has two distinct variants like most other US time zones. Alaska Standard Time (AKST) is nine hours behind Coordinated Universal Time (UTC), while Alaska Daylight Time (AKDT) is eight hours behind UTC.
Aleutian Time Zone
The Aleutian Islands are a group of several dozen islands divided between Russia and Alaska. These islands are included in the Hawaii-Aleutian Time Zone, which as its name suggests, also covers the US state of Hawaii. This time zone is ten hours behind UTC, and the Aleutian Islands do observe daylight savings time and pass to nine hours behind UTC during these periods.
Daylight Savings in Alaska
The whole of Alaska utilizes daylight savings time, including the Aleutian Islands. During the summer months, the majority of the state observes AKDT and is eight hours behind UTC, while the islands are nine hours behind instead. The concept of daylight savings was introduced to Alaska at the same time as all the other US states in 1967.
