Istanbul and Cologne Time Zone Comparison
This page is built for anyone planning a call or meeting between Istanbul and Cologne. Istanbul is Turkey's largest city and historic capital, uniquely straddling Europe and Asia across the Bosphorus strait. Cologne, one of Germany's largest cities on the Rhine, is a historic center known for its famous cathedral and is also home to one of the country's largest Turkish communities.
Because Istanbul and/or Cologne observe daylight saving time for part of the year, the gap between them isn't fixed — it ranges between 1 and 2 hours depending on the season.
With such a small gap, scheduling a call between Istanbul and Cologne is easy — a normal business-hours slot works for both sides on the same calendar day.
