HST to AKST — Hawaii to Alaska Time

Alaska Time is 1 hour ahead of Hawaii in winter and 2 hours ahead in summer.

The conversion rule

During Alaska's standard-time months, add 1 hour to Hawaii Time: 12:00 PM HST is 1:00 PM AKST. Hawaii never changes clocks, so under AKDT the step is 2 hours — noon HST is 2:00 PM in Anchorage.

These neighbors keep long shared hours: 9:00 AM–4:00 PM HST / 10:00 AM–5:00 PM AKT in winter, narrowing to 9:00 AM–3:00 PM HST / 11:00 AM–5:00 PM AKT in summer.

Rows show the 1-hour winter conversion (first Sunday of November through the second Sunday of March). While Alaska observes AKDT — Mar 8 to Nov 1, 2026 — add 2 hours.

Reverse direction: AKST to HST (subtract 1 hour in winter, 2 in summer). Related: HST to EST, HST to CST, HST to MST.

Frequently asked questions

Why is Anchorage 1 hour ahead of Honolulu in December but 2 in June?

Alaska observes daylight saving (AKST UTC−9, AKDT UTC−8) while Hawaii holds HST (UTC−10) permanently. The gap is 1 hour in the standard-time months and 2 hours under AKDT.

Are the Aleutian Islands on Hawaii time?

The islands west of 169°30′ W use the Hawaii–Aleutian zone, but they observe DST while Hawaii doesn't — so they match Honolulu's clock only in winter.

What is 3:00 PM HST in Alaska?

4:00 PM AKST in winter; in summer 3:00 PM HST is 5:00 PM AKDT.
