Most of Alaska sits in the Alaska Time Zone, which is nine hours behind Coordinated Universal Time during standard time (UTC−09:00) and eight hours behind during daylight saving time (UTC−08:00). However, navigating the state's official clock requires looking closer at its massive geography. Because the state spans a staggering distance from east to west, it actually covers two distinct time zones.
Understanding how time works across the Last Frontier helps prevent missed flights, botched business calls, and scheduling errors. Whether you're planning a trip or coordinating remote work, here's what you need to know about Alaska's unique setup.
The Two Alaska Time Zones
While the vast majority of residents live under one umbrella, Alaska splits its timekeeping into two distinct legal zones.
1. Alaska Standard Time (AKST)
Covering about 99% of the state—including major population centers like Anchorage, Fairbanks, Juneau, and Nome—this zone operates on UTC−09:00 during the winter months. When it's noon in Anchorage, it's 1:00 PM on the West Coast of the United States (Pacific Time) and 4:00 PM on the East Coast (Eastern Time).
2. Hawaii-Aleutian Standard Time (HAST)
The westernmost reaches of the state shift further back. The Aleutian Islands chain, stretching westward past the Alaska Peninsula toward the Bering Sea, operates on Hawaii-Aleutian Standard Time (UTC−10:00 during standard time). Communities like Adak sit one full hour behind Anchorage and the rest of the state. If you call someone in the western Aleutians from Fairbanks, you'll need to remember that they are an hour behind your local clock.
Daylight Saving Time Rules in Alaska
Unlike Arizona and Hawaii, Alaska does observe Daylight Saving Time (DST). The state springs forward and falls back right along with most of the United States.
- Spring Forward: On the second Sunday in March at 2:00 AM local time, clocks move forward one hour, shifting the offset from UTC−09:00 to UTC−08:00 (Alaska Daylight Time, or AKDT).
- Fall Back: On the first Sunday in November at 2:00 AM local time, clocks return to standard time (UTC−09:00).
Because Alaska sits so far north, daylight saving time interacts strangely with its extreme seasonal daylight swings. Residents don't change clocks to gain daylight during dark winters; rather, DST is maintained in the summer months to maximize evening daylight during the endless summer nights. You can track official atomic time adjustments through the National Institute of Standards and Technology.
A Quirky Exception: The Town of Hyder
Geography occasionally creates messy borders that official maps struggle to handle cleanly. Take Hyder, a tiny unincorporated community in Southeast Alaska located near the Canadian border.
Because Hyder is economically integrated with its neighboring Canadian town of Stewart, British Columbia, residents there largely ignore the official Alaska time zone. Instead, Hyder unofficially operates on Pacific Time to stay in sync with local schools, stores, and commerce across the border. If you visit Hyder, your smartphone might automatically flip back and forth between time zones depending on which cell tower it pings.
Common Mistakes to Avoid
Managing schedules across Alaska's vast distances leads to predictable errors for travelers and remote workers. Keep these pitfalls in mind:
- Assuming the whole state shares one hour: Forgetting about the Aleutian Islands offset is a common mistake when scheduling logistics or flights out west.
- Confusing Pacific and Alaska time: People frequently mix up Pacific Time (UTC−8) with Alaska Time (UTC−9), assuming a smaller time gap than actually exists. Always double-check meeting times using a reliable world clock tool.
- Misjudging seasonal shifts: Remember that Alaska changes its clocks in March and November. If you schedule a call with a Fairbanks local in October, the math differs from a call placed in December.

Frequently Asked Questions
How many hours behind is Alaska from New York?
Alaska is four hours behind New York (Eastern Time) during standard time. When it is noon in New York, it is 8:00 AM in Anchorage.
Does all of Alaska use the same time zone?
No. While Anchorage, Fairbanks, and Juneau share the primary Alaska Time Zone, the western Aleutian Islands use Hawaii-Aleutian Standard Time, making them one hour behind the rest of the state.
Why does Alaska observe Daylight Saving Time?
Alaska follows federal standard practices for DST to keep commercial, aviation, and digital schedules aligned with the rest of the United States, despite its unique northern latitude.
When did Alaska consolidate its time zones?
Alaska historically had four separate time zones. In 1983, the region consolidated down to its current primary structure to simplify commerce and communication across the territory.
