Frequently Asked Questions
What is the time difference between GMT and AKST?
During standard time, Alaska Standard Time is 9 hours behind Greenwich Mean Time.
What is the difference between GMT and BST?
GMT (Greenwich Mean Time) is the UK's standard winter offset at UTC+0, observed from the last Sunday in October through the last Sunday in March. BST (British Summer Time) is the daylight saving offset at UTC+1, applied each summer when clocks advance one hour.
Is GMT the same as UTC?
GMT and UTC share exactly the same numerical offset — both represent UTC+00:00 — but they are fundamentally different in nature. UTC is an atomic-clock-based international time standard used as the global reference, while GMT is a geographic time zone legally observed by specific countries including the United Kingdom and Ireland during winter months.
Does Alaska observe Daylight Saving Time?
Most of Alaska observes Daylight Saving Time, transitioning from Alaska Standard Time (AKST, UTC-09:00) to Alaska Daylight Time (AKDT, UTC-08:00) on the second Sunday in March. Clocks revert to AKST on the first Sunday in November, following the same DST schedule as the contiguous United States.
Is all of Alaska on Alaska Standard Time?
Almost all of Alaska uses AKST, but the westernmost Aleutian Island communities — those located west of 169° 30′ W longitude — observe Hawaii-Aleutian Time (HST, UTC-10:00) instead. This exception reflects their extreme western geographic position, which places them closer in solar time to Hawaii than to Anchorage.
