Understanding the Anchorage Time Zone
Anchorage operates on Alaska Standard Time (AKST) during the winter months, sitting at UTC-9. When daylight saving time begins, the city shifts to Alaska Daylight Time (AKDT), moving the offset to UTC-8. This schedule puts Anchorage one hour behind the Pacific Time Zone and four hours behind the Eastern Time Zone for most of the year.
If you're planning a trip, booking flights, or coordinating remote meetings with businesses in Anchorage, knowing these shifts prevents missed connections. Because Alaska observes daylight saving time, clocks spring forward on the second Sunday in March and fall back on the first Sunday in November.
Seasonal Shifts and Daylight Changes
The transition between standard and daylight time alters daily light exposure drastically across Alaska's largest metropolitan hub. During mid-winter, Anchorage experiences less than six hours of daylight, while summer months bring nearly 20 hours of sunlight.
- Spring Forward: On the second Sunday in March at 2:00 AM local time, clocks move ahead one hour to 3:00 AM, shifting the offset from UTC-9 to UTC-8.
- Fall Back: On the first Sunday in November at 2:00 AM local time, clocks move back one hour to 1:00 AM, returning the region to UTC-9.
These shifts align with the National Institute of Standards and Technology official timekeeping standards used across the United States. Visitors often forget that Alaska spends a larger portion of the year on daylight saving time than standard time due to the timing of these changes.
Comparing Anchorage to Major U.S. Time Zones
Managing schedules across state lines requires clear conversion math. Anchorage sits west of the contiguous United States, meaning local time lags behind the rest of the country.
- Eastern Time (New York, Miami): Anchorage is four hours behind. When it's noon in New York during standard time, it's 8:00 AM in Anchorage.
- Central Time (Chicago, Dallas): Anchorage is three hours behind.
- Mountain Time (Denver, Phoenix): Anchorage is two hours behind. Arizona mostly stays on standard time, which shifts the math during summer months.
- Pacific Time (Los Angeles, Seattle): Anchorage is one hour behind. A 5:00 PM call in Seattle is 4:00 PM in Anchorage.
- Hawaii-Aleutian Time (Honolulu): Hawaii does not observe daylight saving time, meaning Anchorage is one hour ahead of Honolulu in the winter and shares the exact same clock time during the summer.
Common Scheduling Mistakes to Avoid
Travelers and remote workers frequently run into trouble when booking early morning or late evening transport. Airlines operating out of Ted Stevens Anchorage International Airport list all departure and arrival times in local Alaska time. If you land at midnight, your phone might automatically sync, but older analog gear or manual watches will require a manual adjustment.
Another frequent error involves assuming the entire state shares one uniform clock. While Anchorage, Fairbanks, and Juneau share the Alaska Time Zone, the westernmost Aleutian Islands sit in the Hawaii-Aleutian Time Zone, making them an additional hour behind Anchorage.
