Time-zone overlap between Estonia and Ankara, winter and summer
Ankara runs on UTC+3 all year because Türkiye does not use daylight saving time. Estonia runs on UTC+2 in winter and UTC+3 in summer. In winter Ankara is one hour ahead: when our day starts at 09:00 it is 08:00 in Tallinn, and when it ends at 18:00 it is 17:00 there. Your 09:00 start is 10:00 in Ankara, so a standard 09:00 to 18:00 day shares 8 hours. In summer the clocks match and all 9 hours overlap. There is no overnight gap to design around, so the weekly call can sit anywhere inside the shared hours. Work runs on Türkiye business hours, and we still keep decisions written and asynchronous, because a written decision survives holidays and new joiners.
