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