There is no time difference between Vilnius and Tallinn. Both cities use Eastern European Time (EET/EEST, UTC+2/+3). When it's 12:00 PM in Vilnius, it's also 12:00 PM in Tallinn.
Both cities observe daylight saving time on the same schedule as part of the European Union, so they remain synchronized year-round.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 6:00 PM) without any time conversion needed.
Vilnius and Tallinn are Baltic capitals with similar histories as former Soviet republics that are now thriving EU members. The Via Baltica highway connects them through Riga, Latvia. Both cities have UNESCO-listed Old Towns and growing digital economies.
