Izmir and Cologne Time Zone Comparison
Izmir and Cologne are two major cities that sit in noticeably different time zones. Izmir is Turkey's largest city on the Aegean coast and the country's third most populous, known for its long history as a port city. 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 Izmir 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 Izmir and Cologne is easy — a normal business-hours slot works for both sides on the same calendar day.
