Why people convert AKST to Istanbul time
- Scheduling a call from AKST to Istanbul: a 10:00 AM start in AKST lands at 10:00 PM in Istanbul, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +12h gap: AKST and Istanbul 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 Istanbul is 9:00 PM in AKST.
- Keeping family and friends in sync: knowing that 8:00 PM in AKST is 8:00 AM in Istanbul makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM AKST" 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 AKST takes the early slot, the next week Istanbul does.
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 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.
Best time to call between AKST and Istanbul
With a +12h offset there is no overlap inside a normal 9 AM – 5 PM day. Istanbul opens at 9:00 AM TRT, which is 9:00 PM in AKST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
