Istanbul and Atlanta Time Zone Comparison
Istanbul and Atlanta are two major cities that sit in noticeably different time zones. Istanbul and Atlanta sit on different continents, in noticeably different time zones, and at least one of them observes daylight saving time.
Because Istanbul and/or Atlanta observe daylight saving time for part of the year, the gap between them isn't fixed — it ranges between 7 and 8 hours depending on the season.
With a gap this large, business hours barely overlap between Istanbul and Atlanta — an early morning or a late evening on one side is usually needed to connect with the other.
