Understanding the -9h Gap: Dublin vs Anchorage
Dublin runs on Irish Standard Time (IST) at UTC+01:00, currently observing daylight saving time. Anchorage runs on Alaska Daylight Time (AKDT) at UTC-08:00, also currently on daylight saving time. That puts Dublin 9 hours behind Anchorage — a difference of -9h at the current offsets.
In practice, when it is 9:00 AM in Dublin it is 12:00 AM in Anchorage. Midnight in Dublin is 3:00 PM in Anchorage. 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 Dublin to Anchorage time
- Scheduling a call from Dublin to Anchorage: a 10:00 AM start in Dublin lands at 1:00 AM in Anchorage, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: Dublin and Anchorage 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 Anchorage is 12:00 AM in Dublin.
- Keeping family and friends in sync: knowing that 8:00 PM in Dublin is 11:00 AM in Anchorage makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" 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 Dublin takes the early slot, the next week Anchorage does.
- Dublin: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -9h gap.
- Anchorage: Clocks fall back on Sun, Nov 1, 2026. Any meeting series spanning that date will shift by an hour in local time.
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.
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).
