Best Meeting Time: London to Istanbul
🕐 Live Timezone Overlap: London & Istanbul
London and Istanbul sit just 2 hours apart, which makes scheduling between them relatively straightforward compared with many international pairings. Istanbul is ahead. That gap gives both cities a generous 7-hour window of shared working time each day, running 9am to 4pm in London and 11am to 6pm in Istanbul. The main scheduling consideration is London's observance of daylight saving time, which Istanbul does not follow, meaning the offset shifts twice a year.
Time Difference: London and Istanbul
Istanbul is currently 2 hours ahead of London. The live offsets are London UTC+1 and Istanbul UTC+3. London observes daylight saving and Istanbul does not, so the offset shifts twice a year if both sides aren't already aligned.
Istanbul runs UTC+3 year-round. Turkey abolished DST in 2016, so the clocks there never change. London currently sits at UTC+1, meaning the gap between London and Istanbul is 2 hours right now. In winter, when London returns to UTC+0, that gap widens to 3 hours. The shared working-day overlap narrows accordingly in winter months, so teams should recalculate their meeting windows each time the UK clocks change in late October.
Best Times to Meet
The 7-hour overlap runs from 9am to 4pm London time, or 11am to 6pm Istanbul time. Inside that 7-hour window, the cleanest slot is typically 10am to 1pm London (noon to 3pm Istanbul): it avoids the London lunch hour of 12:30 to 1:30pm and falls well within active Istanbul working hours. Friday afternoons are worth avoiding in Istanbul, where Friday lunch can extend for observant Muslim staff. During Ramadan, Istanbul-side afternoons may also be shortened at many companies.

Tips for Scheduling Across London and Istanbul
- Book recurring calls before 1pm London time to stay clear of the London lunch hour and keep Istanbul colleagues comfortably mid-afternoon.
- When UK clocks fall back in late October, the London-Istanbul gap widens to 3 hours: update any standing meeting invites immediately.
- Check the lunar calendar for Eid al-Fitr and Eid al-Adha dates early; Istanbul offices may close for several consecutive days around each.
- Avoid scheduling Istanbul calls on 29 October, Republic Day, which is a firm public holiday across Turkey including Istanbul.
- For Friday calls, aim for before noon London time, as Istanbul Friday lunches can run long and London offices often slow from mid-afternoon.
Public Holidays and Working Weeks
Both cities follow a Monday-to-Friday working week, with standard hours of 9am to 6pm. London offices often wind down by 4pm on Fridays. Key London holidays include New Year's Day, the May Bank Holiday, and Christmas Day. Istanbul observes Republic Day on 29 October and two movable Eid holidays tied to the lunar calendar. Because Eid dates shift each year and affect multiple consecutive days, cross-city meetings should verify both calendars well in advance.
