Understanding the +9h Gap: Anchorage vs London
Anchorage runs on Alaska Daylight Time (AKDT) at UTC-08:00, currently observing daylight saving time. London runs on British Summer Time (BST) at UTC+01:00, also currently on daylight saving time. That puts Anchorage 9 hours ahead of London — a difference of +9h at the current offsets.
In practice, when it is 9:00 AM in Anchorage it is 6:00 PM in London. Midnight in Anchorage is 9:00 AM in London. Because both zones shift for daylight saving, the gap between them only changes during the few weeks each year when their transition dates differ.

Why people convert Anchorage to London time
- Scheduling a call from Anchorage to London: a 10:00 AM start in Anchorage lands at 7:00 PM in London, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: Anchorage and London have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in London is 6:00 PM in Anchorage.
- Coordinating a Anchorage-based team with London contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM AKDT" is unambiguous; "3 PM" across a +9h gap is not.
- With a +9h gap there is no shared 9-to-5 window, so alternate the early start: one week Anchorage takes the early slot, the next week London does.
- Anchorage: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +9h gap.
- London: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
About AKST (Alaska Standard Time)
Alaska Standard Time (AKST) is used in nearly all of Alaska. Due to Alaska's vast geographic size, the Aleutian Islands use Hawaii-Aleutian Standard Time instead. During summer months, Alaska switches to Alaska Daylight Time (AKDT, UTC-08:00).
About GMT (Greenwich Mean Time)
Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.
