Istanbul and Oslo Time Zone Comparison
This page is built for anyone planning a call or meeting between Istanbul and Oslo. Istanbul is in the Middle East and Oslo is in Europe — thousands of kilometers apart.
Because Istanbul and/or Oslo 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 Oslo is easy — a normal business-hours slot works for both sides on the same calendar day.
