Istanbul and Siauliai Time Zone Comparison
Istanbul and Siauliai are two major cities that sit in noticeably different time zones. Siauliai is in Europe, while Istanbul sits in the Middle East; their daylight saving rules also differ.
Because Istanbul and/or Siauliai observe daylight saving time for part of the year, the gap between them isn't fixed — it ranges between 0 and 1 hours depending on the season.
With such a small gap, scheduling a call between Istanbul and Siauliai is easy — a normal business-hours slot works for both sides on the same calendar day.
