Why people convert Istanbul to AKST time

  • Scheduling a call from Istanbul to AKST: a 10:00 AM start in Istanbul lands at 10:00 PM in AKST the previous day, so you can confirm the slot without doing the arithmetic yourself.
  • Handling a -12h gap: Istanbul 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 9:00 PM in Istanbul.
  • Watching a live event or market open: Istanbul viewers need 9:00 PM in AKST to catch a 9:00 AM start there, and 12:00 PM if the event is anchored to Istanbul.
  • Always state the zone abbreviation, not just the hour. "3:00 PM TRT" is unambiguous; "3 PM" across a -12h gap is not.
  • With a -12h gap there is no shared 9-to-5 window, so alternate the early start: one week Istanbul takes the early slot, the next week AKST does.

About TRT (Turkey Time)

Turkey Time (TRT) is fixed at UTC+03:00 all year. Turkey abolished seasonal clock changes in September 2016, moving to a permanent UTC+03:00 so the whole country stays on what was formerly summer time. That leaves Istanbul, which sits close to 29°E, on an offset well ahead of its solar time — sunrise in mid-winter comes after 08:30 local. TRT shares its offset with Moscow Standard Time, Arabia Standard Time and East Africa Time, so Istanbul is level with Moscow and Riyadh all year and one hour ahead of Central European Time during the European winter.

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 Istanbul and AKST

With a -12h offset there is no overlap inside a normal 9 AM – 5 PM day. AKST opens at 9:00 AM AKST, which is 9:00 PM in Istanbul, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Istanbul and AKST have no shared working hours because of the -12h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Istanbul is 12 hours behind AKST (TRT UTC+03:00 → 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.
