Why people convert Johannesburg to Istanbul time
- Scheduling a call from Johannesburg to Istanbul: a 10:00 AM start in Johannesburg lands at 11:00 AM in Istanbul, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Johannesburg and Istanbul are inside the 9-to-5 working day between 9:00 AM and 4:00 PM SAST time (10:00 AM–5:00 PM TRT). That is roughly 7 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Johannesburg is 9:00 PM in Istanbul makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM SAST" is unambiguous; "3 PM" across a +1h gap is not.
- Block 9:00 AM–4:00 PM SAST as the recurring meeting window if you work primarily from Johannesburg and need Istanbul colleagues present.
About SAST (South Africa Standard Time)
South Africa Standard Time (SAST) is used in South Africa, Lesotho, and Eswatini. SAST does not observe daylight saving time. Johannesburg and Cape Town are major economic hubs in Africa.
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.
