TRT and CAT on the World Map
The map below highlights the TRT (Turkey Time) and CAT (Central Africa Time) timezone regions across the globe.
TRT – Turkey Time
UTC+03:00Turkey Time (TRT, UTC+03:00) is the single time zone used across Turkey, fixed year round since 2016.
- •Turkey has used a permanent UTC+03:00 since September 2016.
- •TRT is level with Moscow Standard Time and Arabia Standard Time all year.
- •Because Turkey kept summer time permanently, western cities see very late winter sunrises.
- •Turkey previously observed daylight saving time from 1973 to 2016.
CAT – Central Africa Time
UTC+02:00Central Africa Time (CAT, UTC+02:00) covers Zimbabwe, Zambia, Mozambique, Malawi and neighbouring countries.
- •Central Africa Time is fixed at UTC+02:00 with no daylight saving.
- •CAT matches South Africa Standard Time (SAST) all year.
- •It is the same offset as Central European Time in winter.
- •Harare is level with Johannesburg and one hour ahead of Lagos.
Understanding the -1h Gap: TRT vs CAT
TRT runs on Turkey Time (TRT) at UTC+03:00. CAT runs on Central Africa Time (CAT) at UTC+02:00. That puts TRT 1 hour behind CAT — a difference of -1h at the current offsets.
In practice, when it is 9:00 AM in TRT it is 8:00 AM in CAT. Midnight in TRT is 11:00 PM in CAT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert TRT to CAT time
- Scheduling a call from TRT to CAT: a 10:00 AM start in TRT lands at 9:00 AM in CAT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both TRT and CAT are inside the 9-to-5 working day between 10:00 AM and 5:00 PM TRT time (9:00 AM–4:00 PM CAT). That is roughly 7 hours of usable overlap.
- Coordinating a TRT-based team with CAT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM TRT" is unambiguous; "3 PM" across a -1h gap is not.
- Block 10:00 AM–5:00 PM TRT as the recurring meeting window if you work primarily from TRT and need CAT 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 CAT (Central Africa Time)
Central Africa Time (CAT) is fixed at UTC+02:00 all year across a broad belt of southern and central Africa, including Zimbabwe, Zambia, Mozambique, Malawi, Rwanda, Burundi and the eastern Democratic Republic of the Congo. None of these countries observes daylight saving time, so CAT never shifts. It is the same offset as South Africa Standard Time (SAST) and the winter version of Central European Time, which makes CAT a convenient bridge between African, European and Middle Eastern schedules — Harare is level with Johannesburg all year and one hour ahead of Lagos.
Best time to call between TRT and CAT
Both TRT and CAT sit inside the 9 AM – 5 PM working day between 10:00 AM–5:00 PM TRT, which is 9:00 AM–4:00 PM CAT. That gives roughly 7 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
TRT and CAT share 7 hours of working-hours overlap (10:00 AM–5:00 PM TRT), so scheduling a live meeting is straightforward.
TRT is 1 hour behind CAT (TRT UTC+03:00 → CAT UTC+02:00). The shared working window is 10:00 AM–5:00 PM TRT. Remember to re-check around daylight-saving transitions.
