Hawaii-Aleutian Time

HST (UTC−10) — Hawaii never observes Daylight Saving Time · Aleutian Islands use HAST (UTC−10) / HADT (UTC−9)

Used in Hawaii (all islands) · Aleutian Islands of Alaska use the same base offset

ABOUT HAWAII-ALEUTIAN TIME

Hawaii Standard Time (HST) is the timezone used by the state of Hawaii and is fixed at UTC−10 year-round. It is one of the most distinctive timezones in the United States because Hawaii is the only US state that has never observed Daylight Saving Time in the modern era. The state was formally exempted from the federal Uniform Time Act in 1967, and has maintained its permanent UTC−10 offset ever since.

The "Hawaii-Aleutian" designation in the timezone's official name refers to the Aleutian Islands of Alaska, which share the same base UTC−10 offset in winter. However, unlike Hawaii, the Aleutian Islands do observe Daylight Saving Time, switching to HADT (UTC−9) in summer. This creates an unusual situation where two geographically distant regions share a timezone name but diverge in practice for roughly eight months of the year.

Hawaii's permanent UTC−10 offset means it is always two hours behind the US West Coast in winter and three hours behind in summer (when California observes PDT). The state is five hours behind New York in winter and six hours behind in summer. This large and variable gap with the continental US is a practical consideration for businesses, travellers, and remote workers connecting between Hawaii and the mainland.

The Hawaiian island chain spans roughly 2,400 km (1,500 miles) from the Big Island in the southeast to Kure Atoll in the northwest, yet the entire state uses a single timezone. This is partly because the islands are relatively close in longitude compared to a continental state, and partly because the social and economic ties between the islands make a unified timezone practical.

HISTORY OF HAWAII TIME

1898
Hawaii annexed by the United States
Following the Spanish-American War, Hawaii is formally annexed as a US territory. At this time, local timekeeping is informal and based on solar noon, with Honolulu roughly at UTC−10:30.
1900
Standard time introduced in Hawaii
The US Congress extends standard time to US territories. Hawaii adopts a fixed offset of UTC−10:30, aligning with its geographic longitude.
1933
Hawaii briefly experiments with DST
During the New Deal era, Hawaii briefly experiments with Daylight Saving Time, advancing clocks by 30 minutes in summer. The experiment is short-lived and unpopular.
1947
Hawaii observes DST for the last time
Hawaii advances its clocks for the final time. After 1947, the territory abandons Daylight Saving Time permanently, citing its tropical latitude and the minimal benefit of extended evening daylight.
1959
Hawaii becomes the 50th US state
Hawaii is admitted to the Union on August 21, 1959. The new state adopts a rounded offset of UTC−10, dropping the historical UTC−10:30 offset.
1967
Formally exempted from the Uniform Time Act
The US Congress passes the Uniform Time Act, standardising Daylight Saving Time nationally. Hawaii is granted an explicit exemption, making its permanent UTC−10 offset federal law.
1983
Aleutian Islands consolidated into HAST
The US Department of Transportation reorganises Alaskan timezones. The Aleutian Islands west of 169°30′W are placed in the Hawaii-Aleutian timezone (HAST/HADT), giving the timezone its current dual name.
