The Alaska Time Zone observes standard time by subtracting nine hours from Coordinated Universal Time (UTC-9). The UTC−9 time zone is used in French Polynesia Gambier Islands United States (AKST— Alaska Standard Standard time is the result of synchronizing clocks in different geographical locations within a Time zone to the same time rather than using the local meridian as The UTC−9 time zone is used in French Polynesia Gambier Islands United States (AKST— Alaska Standard During daylight saving time its time offset is only eight hours (UTC-8). Daylight saving time ( DST A time offset is defined by international convention as a number of hours and minutes from Coordinated Universal Time in Greenwich England. UTC−8 is a band of Timezones separated from the Universal Coordinated Time by 8 hours The clock time in this zone is based on the mean solar time of the 135th degree meridian west of the Greenwich Observatory. Solar times are measures of the apparent position of the Sun on the Celestial sphere. This article is about the geographical concept For other uses of the word see Meridian. The Royal Observatory Greenwich (formerly the Royal Greenwich Observatory or RGO) was commissioned in 1675 by King Charles II, with the
The zone includes nearly all of the U. S. state of Alaska and is one hour behind the Pacific Time Zone. Alaska ( Аляска Alyaska) is a state in the United States of America, in the northwest of the North American continent The Pacific Time Zone observes Standard time by subtracting eight hours from Coordinated Universal Time ( UTC-8)
The western Aleutians observe Hawaii-Aleutian Time, one hour behind the remainder of the state. The Hawaii-Aleutian Time Zone observes Hawaii-Aleutian Standard Time (HST by subtracting ten hours from Coordinated Universal Time ( UTC-10)
Effective 2007, the local time changes from AKST to AKDT at 02:00 LST to 03:00 LDT on the second Sunday in March and returns at 02:00 LDT to 01:00 LST on the first Sunday in November.
The original Alaska time zone was actually known as Alaska-Hawaii Standard Time Zone; that zone is now known as Hawaii-Aleutian Time Zone.
The Alaska Time Zone is the same as what the Yukon Standard Time Zone (YST) was. The Yukon Standard Time Zone (YST was a geographic region that kept Standard time by subtracting nine hours from Coordinated Universal Time (UTC resulting in However, the Yukon Territory switched to the Pacific Standard Time Zone in 1975 and the time zone was not used (except for Yakutat) until 1983 when the state of Alaska decided to move most of the state to UTC-9. Yukon (ˈjuːkɒn is the westernmost and smallest of Canada's three territories. The Pacific Time Zone observes Standard time by subtracting eight hours from Coordinated Universal Time ( UTC-8) Yakutat City and Borough (ˈjækətɑːt is a unified city- borough in the U Prior to that the Alaska Panhandle communities were on the Pacific Time Zone, while most of the interior was on UTC-10. The Alaska Panhandle, sometimes referred to as Southeast Alaska, is the southeastern portion of the U The UTC−10 Time offset is used in Cook Islands French Polynesia Society Archipelago including Nome and the Aleutians previously observed Bering Standard Time or UTC-11.

The Alaska Time Zone is applied to the territory of the state of Alaska to the east of 169°30′ W. Alaska ( Аляска Alyaska) is a state in the United States of America, in the northwest of the North American continent Given that the UTC−9 time corresponds to the solar time at 9 × 15° = 135° W (roughly, Juneau), the westernmost locales where Alaska time gets applied are off by 169°30′ − 135° = 34°30′ from their 'physical' time. This means that when a clock correctly set to Alaskan time, at a location just east of 169°30′ W, shows noon, the 'physical' time is actually just 9:42 am. When UTC−8 is applied in the summer, this effect becomes even more apparent, since the solar time at Fresno, California (about 120° W) is used. At a (say) July noon, the physical time at the extreme westerly points of the Alaskan time zone will actually be only 8:42 a. m.
In Anchorage, visitors from more southerly latitudes are often surprised to see the sun set at 11:41 pm on the summer solstice, but the actual 'physical time' is 9:41 pm. Solstices occur twice a year when the tilt of the Earth's axis is most oriented toward or away from the Sun, causing the Sun to reach its northernmost and southernmost extremes This is because at 150° W, Anchorage is a full solar hour behind the legal time zone and observes daylight saving time as well. Some local residents refer to this phenomenon as "double daylight time". In Fairbanks, the same circumstances cause sunset to occur at 12:47 am on the next calendar day. In the winter, even without daylight saving time, another anomaly is that on the winter solstice in Nome, the sunrise is actually after "noon" clock time, at 12:02 pm lasting for about 3 hours before sunset. Nome is a city located on the southern Seward Peninsula coast on Norton Sound of the Bering Sea
