Istanbul and Warsaw Time Zone Comparison
The distance between Istanbul and Warsaw is felt not just in kilometers, but in time zones too. Warsaw is in Europe, while Istanbul sits in the Middle East; their daylight saving rules also differ.
Because Istanbul and/or Warsaw 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 Warsaw is easy — a normal business-hours slot works for both sides on the same calendar day.
