- •The Royal Observatory in Greenwich has been the reference point for GMT since 1884.
- •GMT and UTC are often used interchangeably, but UTC is based on atomic clocks.

- •The UK switches from GMT to BST (British Summer Time) in late March each year.
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.

Why people convert Ireland to Turkey time
- Scheduling a call from Ireland to Turkey: a 10:00 AM start in Ireland lands at 12:00 PM in Turkey, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Ireland and Turkey are inside the 9-to-5 working day between 9:00 AM and 3:00 PM IST time (11:00 AM–5:00 PM TRT). That is roughly 6 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Ireland is 10:00 PM in Turkey makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +2h gap is not.
- Block 9:00 AM–3:00 PM IST as the recurring meeting window if you work primarily from Ireland and need Turkey colleagues present.
- Ireland: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +2h gap.
About GMT (Greenwich Mean Time)
Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.
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.
Best time to call between Ireland and Turkey
Both Ireland and Turkey sit inside the 9 AM – 5 PM working day between 9:00 AM–3:00 PM IST, which is 11:00 AM–5:00 PM TRT. That gives roughly 6 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
Ireland and Turkey share 6 hours of working-hours overlap (9:00 AM–3:00 PM IST), so scheduling a live meeting is straightforward.
Ireland is 2 hours ahead of Turkey (IST UTC+01:00 → TRT UTC+03:00). The shared working window is 9:00 AM–3:00 PM IST. Remember to re-check around daylight-saving transitions.
