TRT and NST on the World Map
The map below highlights the TRT (Turkey Time) and NST (Newfoundland Standard 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.
NST – Newfoundland Standard Time
UTC-03:30Newfoundland Standard Time (NST) is a unique half-hour offset time zone in Canada, 3.5 hours behind UTC.
- •NST is one of only a few half-hour offset time zones in the world.
- •Newfoundland joined Canada in 1949 and kept its unique time zone.
- •St. John's is the easternmost city in North America.
Comparing Time Zones: TRT and NST
TRT runs on Turkey Time (TRT) at UTC+03:00. NST runs on Newfoundland Standard Time (NST) at UTC-03:30. That puts TRT 6 hours 30 minutes behind NST — a difference of -6h 30m at the current offsets.
In practice, when it is 9:00 AM in TRT it is 2:30 AM in NST. Midnight in TRT is 5:30 PM in NST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert TRT to NST time
- Scheduling a call from TRT to NST: a 10:00 AM start in TRT lands at 3:30 AM in NST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both TRT and NST are inside the 9-to-5 working day between 3:30 PM and 5:00 PM TRT time (9:00 AM–10:30 AM NST). That is roughly 1 hours 30 minutes of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in TRT is 1:30 PM in NST makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM TRT" is unambiguous; "3 PM" across a -6h 30m gap is not.
- Block 3:30 PM–5:00 PM TRT as the recurring meeting window if you work primarily from TRT and need NST 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 NST (Newfoundland Standard Time)
Newfoundland Standard Time (NST) is one of the few half-hour offset time zones in the world. It covers the island of Newfoundland in Canada and is 30 minutes ahead of Atlantic Standard Time. This unique offset exists because Newfoundland was an independent country until 1949.
Best time to call between TRT and NST
Both TRT and NST sit inside the 9 AM – 5 PM working day between 3:30 PM–5:00 PM TRT, which is 9:00 AM–10:30 AM NST. That gives roughly 1 hours and 30 minutes of shared time — the safest window for a live call or meeting.
Business hours overlap
TRT and NST overlap for only 90 minutes (3:30 PM–5:00 PM TRT), so meetings have to be booked precisely.
TRT is 6 hours 30 minutes behind NST (TRT UTC+03:00 → NST UTC-03:30). The shared working window is 3:30 PM–5:00 PM TRT. Remember to re-check around daylight-saving transitions.
