- Finding shared working hours: both Athens and Istanbul are inside the 9-to-5 working day between 9:00 AM and 5:00 PM EEST time (9:00 AM–5:00 PM TRT). That is roughly 8 hours of usable overlap.
- Watching a live event or market open: Athens viewers need 9:00 AM in Istanbul to catch a 9:00 AM start there, and 12:00 AM if the event is anchored to Athens.
- Always state the zone abbreviation, not just the hour. "3:00 PM EEST" is unambiguous; "3 PM" across a +0h gap is not.

About EET (Eastern European Time)
Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya). During summer, most EET countries switch to Eastern European Summer Time (EEST, UTC+03:00). Turkey permanently moved to UTC+03:00 in 2016, effectively leaving EET.
About TRT (Turkey Time)
Turkey Time (TRT) is fixed at UTC+03:00 all year. Turkey abolished seasonal clock changes in September 2016, moving to a permanent UTC+03:00 so the whole country stays on what was formerly summer time. That leaves Istanbul, which sits close to 29°E, on an offset well ahead of its solar time — sunrise in mid-winter comes after 08:30 local. TRT shares its offset with Moscow Standard Time, Arabia Standard Time and East Africa Time, so Istanbul is level with Moscow and Riyadh all year and one hour ahead of Central European Time during the European winter.
