Why people convert Honolulu to Turkey time

Scheduling a call from Honolulu to Turkey: a 10:00 AM start in Honolulu lands at 11:00 PM in Turkey, so you can confirm the slot without doing the arithmetic yourself.
Handling a +13h gap: Honolulu and Turkey 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 Turkey is 10:00 PM in Honolulu.
Watching a live event or market open: Honolulu viewers need 10:00 PM in Turkey to catch a 9:00 AM start there, and 11:00 AM if the event is anchored to Honolulu.

Always state the zone abbreviation, not just the hour. "3:00 PM HST" is unambiguous; "3 PM" across a +13h gap is not.
With a +13h gap there is no shared 9-to-5 window, so alternate the early start: one week Honolulu takes the early slot, the next week Turkey does.

About HST (Hawaii Standard Time)

Hawaii Standard Time (HST) is used in the state of Hawaii and does not observe daylight saving time. This makes HST one of the most consistent time zones in the US. The Hawaiian Islands are among the last places on Earth to see a new calendar day.

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 Honolulu and Turkey

With a +13h offset there is no overlap inside a normal 9 AM – 5 PM day. Turkey opens at 9:00 AM TRT, which is 10:00 PM in Honolulu, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Honolulu and Turkey have no shared working hours because of the +13h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Honolulu is 13 hours ahead of Turkey (HST UTC-10:00 → TRT UTC+03:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
