Hawaii-Aleutian Standard Time (HST)

FAQs

Hawaii-Aleutian Standard Time stretches from the tropical calm of Honolulu to the windswept Aleutian Islands, a region where most clocks stay fixed at UTC−10 but the far-western Aleutians spring forward to UTC−9 during daylight saving—so a single time zone quietly toggles between two offsets in step with the Alaskan coast.

  • Does all of Hawaii use daylight saving time?

    No. Hawaii as a whole stays on UTC−10 year-round; only the Aleutian portion of this region shifts to UTC−9 in summer.

  • Which islands are covered by HST?

    The region includes Hawaii proper (Honolulu) and the Aleutian Islands west of 169°30′W (such as Adak).

  • Why does Adak observe daylight saving?

    Adak follows the same cycle as Alaska’s Aleutian communities, moving clocks forward in spring and back in fall to align daylight hours.

  • What’s unique about this time zone?

    It spans two member zones with different DST behavior: one springs forward, the other doesn’t, all under one region code.

  • Is HST the same as Hawaiian time?

    Mostly—Hawaii itself never changes clocks, but the region label also covers the Aleutian summer shift to UTC−9.

  • When does the DST switch happen?

    It follows the U.S. schedule, typically the second Sunday in March and the first Sunday in November.

  • Does this region exist outside the United States?

    No. Both zones are located in the U.S., specifically Hawaii and the Alaska Aleutian chain.

  • What’s a fun geographical quirk?

    From Honolulu to Adak, the zone spans tropical Pacific beaches to volcanic islands near the International Date Line bridge.
