- •Turkey has used a permanent UTC+03:00 since September 2016.
- •TRT is level with Moscow Standard Time and Arabia Standard Time all year.

- •Turkey previously observed daylight saving time from 1973 to 2016.
BST – British Summer Time
UTC+01:00British Summer Time (BST, UTC+01:00) is the daylight saving period in the United Kingdom, running from late March to late October.
- •BST runs from the last Sunday in March to the last Sunday in October.
- •BST is exactly one hour ahead of GMT, the UK's standard time.
- •During BST, London is 4 hours ahead of New York while the US is on Eastern Daylight Time.

Comparing Time Zones: Turkey and BST
Turkey runs on Türkiye Standard Time (TRT) at UTC+03:00. BST runs on British Summer Time (BST) at UTC+01:00. That puts Turkey 2 hours behind BST — a difference of -2h at the current offsets.
In practice, when it is 9:00 AM in Turkey it is 7:00 AM in BST. Midnight in Turkey is 10:00 PM in BST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Turkey to BST time
- Scheduling a call from Turkey to BST: a 10:00 AM start in Turkey lands at 8:00 AM in BST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Turkey and BST are inside the 9-to-5 working day between 11:00 AM and 5:00 PM TRT time (9:00 AM–3:00 PM BST). That is roughly 6 hours of usable overlap.
- Coordinating a Turkey-based team with BST 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 -2h gap is not.
- Block 11:00 AM–5:00 PM TRT as the recurring meeting window if you work primarily from Turkey and need BST 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 BST (British Summer Time)
British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.
Best time to call between Turkey and BST
Both Turkey and BST sit inside the 9 AM – 5 PM working day between 11:00 AM–5:00 PM TRT, which is 9:00 AM–3:00 PM BST. That gives roughly 6 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
Turkey and BST share 6 hours of working-hours overlap (11:00 AM–5:00 PM TRT), so scheduling a live meeting is straightforward.
Turkey is 2 hours behind BST (TRT UTC+03:00 → BST UTC+01:00). The shared working window is 11:00 AM–5:00 PM TRT. Remember to re-check around daylight-saving transitions.
