Atlanta is 7 hours behind Istanbul
Best overlap: 3:00 PM to 6:00 PM in Istanbul is 8:00 AM to 11:00 AM in Atlanta.
Aim for 3:00 PM to 6:00 PM Istanbul time — that's 8:00 AM to 11:00 AM over in Atlanta. Atlanta is 7 hours behind Istanbul, leaving about 3 hours of daily overlap — enough for most meetings if you don't leave them too late in the day. Keep an eye on the calendar — Atlanta observes daylight saving and Istanbul doesn't, which nudges this window by an hour twice a year.
