Istanbul and Vilnius Time Zone Comparison
Istanbul and Vilnius are two major cities that sit in noticeably different time zones. Istanbul is Turkey's largest city and historic capital, uniquely straddling Europe and Asia across the Bosphorus strait. Vilnius, the capital of Lithuania, has one of the largest and best-preserved historic centers among the Baltic capitals.
Because Istanbul and/or Vilnius 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 Vilnius is easy — a normal business-hours slot works for both sides on the same calendar day.
