History

Before 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]

The Pacific Time Zone (PT) is a time zone encompassing parts of western Canada, the western United States, and western Mexico. Places in this zone observe standard time by subtracting eight hours from Coordinated Universal Time (UTC−08:00). During daylight saving time, a time offset of UTC−07:00 is used.

The Alaska Time Zone observes standard time by subtracting nine hours from Coordinated Universal Time (UTC−09:00). During daylight saving time its time offset is eight hours (UTC−08:00).

<span class="mw-page-title-main">Daylight saving time in the United States</span> Practice of setting the clock forward by one hour in the United states

Most of the United States observes daylight saving time (DST), the practice of setting the clock forward by one hour when there is longer daylight during the day, so that evenings have more daylight and mornings have less. Exceptions include Arizona, Hawaii, and the territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. The Uniform Time Act of 1966 established a uniform set of rules for states opting to observe daylight saving time.

Samoa uses UTC+13:00 as standard time. Until the end of 2011, it used UTC−11:00 as standard time. Samoa observed daylight saving time from 2010 to 2021.

Alaska is officially covered by two time zones - the Alaska Time Zone and the Hawaii–Aleutian Time Zone. The Hawaii–Aleutian Time Zone is used for the Aleutian Islands west of 169°30′W, and the rest of the state uses the Alaska Time Zone. The entirety of Alaska observes daylight saving time.

Time in Fiji is given by Fiji Time (FJT) (UTC+12:00), as standard time, and UTC+13:00 as daylight saving time. Fiji decides year by year whether it will observe DST, and if so for which dates, which are usually a short period between November or December and January. No DST has been observed since 2020–2021.

Time in the Kingdom of the Netherlands is denoted by Central European Time during the winter as standard time in the Netherlands, which is one hour ahead of coordinated universal time (UTC+01:00), and Central European Summer Time (CEST) during the summer as daylight saving time, which is two hours ahead of coordinated universal time (UTC+02:00). The Caribbean Netherlands – which consist of the islands of Bonaire, Sint Eustatius and Saba – all observe Atlantic Standard Time (AST) year-round, which is four hours behind coordinated universal time (UTC−04:00).

<span class="mw-page-title-main">Time in Iceland</span>

Iceland observes UTC+00:00 year-round, known as Greenwich Mean Time or Western European Time. UTC+00:00 was adopted on 7 April 1968 – in order for Iceland to be in sync with Europe – replacing UTC−01:00, which had been the standard time zone since 16 November 1907. Iceland previously observed daylight saving time, moving the clock forward one hour, between 1917 and 1921, and 1939 and 1968. The start and end dates varied, as decided by the government. Between 1941 and 1946, daylight saving time commenced on the first Sunday in March and ended in late October, and between 1947 and 1967 it commenced on the first Sunday in April, in all instances since 1941 occurring and ending at 02:00. Since 1994, there have been an increasing number of proposals made to the Althing to reintroduce daylight saving time for a variety of reasons, but all such proposals and resolutions have been rejected.

<span class="mw-page-title-main">Time in Svalbard</span>

Svalbard, an archipelago in the Arctic Ocean belonging to the Kingdom of Norway, uses Central European Time (CET) during the winter as standard time, which is one hour ahead of Coordinated Universal Time (UTC+01:00), and Central European Summer Time (CEST) during the summer as daylight saving time, which is two hours ahead of Coordinated Universal Time (UTC+02:00). This is shared with the rest of Norway, as is Svalbard's use of daylight saving time, which the territory observes annually by advancing the clock forward on the last Sunday in March and back again on the last Sunday in October. However, as Svalbard experiences midnight sun during the summer due to being located north of the Arctic Circle, it gives daylight saving time no utility, and is only observed in order to make communicating with Norway Proper more convenient. At the 74th parallel north, the midnight sun lasts 99 days and polar night 84 days, while the respective figures at the 81st parallel north are 141 and 128 days.

In Luxembourg, the standard time is Central European Time. Daylight saving time is observed from the last Sunday in March to the last Sunday in October.

Time in Libya is given by a single time zone, officially denoted as Eastern European Time. The zone is also known as Central Africa Time (CAT). Libya has observed EET since 5 November 2012, after it was announced in 2013 that Libya would be on permanent daylight saving time. Libya previously observed several different time zones as standard time and daylight saving time. For residents of western Libya, including Tripoli, solar time is usually one hour behind standard time.
