Hawaii is in the Hawaii–Aleutian Time Zone[1] (HST; UTC−10:00) and does not observe daylight saving time.[2]
History
editBefore 1896, Hawaii did not use a standard time zone. On January 8, 1896, the minister of the interior of the Provisional Government of Hawaii created a standard time zone, Hawaiian Standard Time, which was set at UTC−10:30. Hawaii began observing Hawaiian Standard Time on January 13, 1896, at noon.[3][4] On May 19, 1947, the Hawaii Territorial Legislature approved a bill to change Hawaiian Standard Time to UTC−10:00, which would go into effect on June 8, 1947.[5]
After the Uniform Time Act was passed in 1966, Hawaii was placed in the new Alaska–Hawaii Time Zone. On March 30, 1967, the Hawaii State Legislature chose to exempt the state from using daylight saving time.[6] The zone got its modern name, "Hawaii–Aleutian Time Zone", in 1984.[7]
