Why people convert TRT to Seoul time
- Scheduling a call from TRT to Seoul: a 10:00 AM start in TRT lands at 4:00 PM in Seoul, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both TRT and Seoul are inside the 9-to-5 working day between 9:00 AM and 11:00 AM TRT time (3:00 PM–5:00 PM KST). That is roughly 2 hours of usable overlap.
- Watching a live event or market open: TRT viewers need 3:00 PM in Seoul to catch a 9:00 AM start there, and 6:00 PM if the event is anchored to TRT.
- Always state the zone abbreviation, not just the hour. "3:00 PM TRT" is unambiguous; "3 PM" across a +6h gap is not.
- Block 9:00 AM–11:00 AM TRT as the recurring meeting window if you work primarily from TRT and need Seoul colleagues present.
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.
About KST (Korea Standard Time)
Korea Standard Time (KST) is the time zone used in South Korea. It shares the same UTC offset as Japan Standard Time but is a distinct time zone. South Korea does not observe daylight saving time. Seoul, the capital, is a major global tech and business hub.

Business hours overlap
