Istanbul and Cork Time Zone Comparison
Istanbul and Cork are two major cities that sit in noticeably different time zones. Istanbul and Cork sit on different continents, in noticeably different time zones, and at least one of them observes daylight saving time.
Because Istanbul and/or Cork observe daylight saving time for part of the year, the gap between them isn't fixed — it ranges between 2 and 3 hours depending on the season.
With a moderate gap like this, it's worth checking the suggested call window above before scheduling a meeting between Istanbul and Cork.
