Berlin and Moscow Time Zone Comparison
Berlin and Moscow are two major cities that sit in noticeably different time zones. Moscow is in Europe, while Berlin sits in Europe; their daylight saving rules also differ.
Because Berlin and/or Moscow 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 Berlin and Moscow is easy — a normal business-hours slot works for both sides on the same calendar day.
