Why people convert TRT to Colombia time
- Scheduling a call from TRT to Colombia: a 10:00 AM start in TRT lands at 2:00 AM in Colombia, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: TRT and Colombia have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Colombia is 1:00 AM in TRT.
- Watching a live event or market open: TRT viewers need 1:00 AM in Colombia to catch a 9:00 AM start there, and 8:00 AM 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 -8h gap is not.
- With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week TRT takes the early slot, the next week Colombia does.
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 COT (Colombia Time)
Colombia Time (COT) is used throughout Colombia. Colombia does not observe daylight saving time. COT shares the same offset as EST (UTC-05:00). Bogotá, the capital, is one of the largest cities in South America.
Best time to call between TRT and Colombia

Business hours overlap

TRT is 8 hours behind Colombia (TRT UTC+03:00 → COT UTC-05:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
