Everything You Need to Know About GMT and AKST Time

Why people convert GMT to AKST time
- Scheduling a call from GMT to AKST: a 10:00 AM start in GMT lands at 1:00 AM in AKST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: GMT and AKST 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 AKST is 12:00 AM in GMT.
- Watching a live event or market open: GMT viewers need 12:00 AM in AKST to catch a 9:00 AM start there, and 9:00 AM if the event is anchored to GMT.
- Always state the zone abbreviation, not just the hour. "3:00 PM GMT" 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 GMT takes the early slot, the next week AKST does.
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).
Best time to call between GMT and AKST
With a -9h offset there is no overlap inside a normal 9 AM – 5 PM day. AKST opens at 9:00 AM AKST, which is 12:00 AM in GMT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
GMT and AKST have no shared working hours because of the -9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
GMT is 9 hours behind AKST (GMT UTC+00:00 → AKST UTC-09:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
