Time difference between Istanbul and Honolulu

Honolulu is 13 hours behind Istanbul

Istanbul, Türkiye is UTC+3 · Honolulu, the United States is UTC−10 — on standard time

The gap holds all year

Neither city changes its clocks — Istanbul does not change its clocks and Honolulu does not change its clocks — so 13 hours is the difference in January and in July alike. That is worth knowing about this pair specifically, because most international pairs do move and a recurring meeting between them does not need checking twice a year.

When they can both be at their desks

Nine-to-five in Istanbul and nine-to-five in Honolulu do not overlap at all. With 13 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
