Istanbul (Turkey) runs 8 hours ahead of Chicago (United States). In practical terms, the working day in Istanbul starts while Chicago is still in the early hours or asleep, which is what makes scheduling between the two take a little planning.
Best time to schedule a call or meeting
Standard working hours in Chicago and Istanbul barely overlap, so a live call usually means one side joining early in the morning or late in the evening. The least disruptive option is to catch the very start or end of one city’s working day, or to handle things asynchronously.
A note on daylight saving
Chicago observes daylight saving but Istanbul does not, so the gap between them changes by an hour for part of the year. The 8 hours shown here is the current offset; expect it to shift around the daylight-saving changeovers (typically late March and late October in the Northern Hemisphere).
