About
Working across 6 hours of time difference
A 6 hours offset puts Tokyo and Istanbul in the medium-difficulty band. You typically have a 2–4 hour window each day where both cities are at work — usually early afternoon in the western city, late morning or early afternoon in the eastern one. Keep recurring meetings inside that window.
Daylight Saving Time can shift the gap by an hour twice a year. The North American DST window does not align with the European one, so the offset between Tokyo and Istanbul can drift in late March and again in early November. Use this page to re-check your standing meeting on each transition.
FAQ
What's the best time for a meeting between Tokyo and Istanbul?
Best overlap: 1:00 PM–4:00 PM Tokyo time (2/2 zones in business hours). The strongest business-hour overlap is UTC 4:00–8:00, which is Tokyo 1:00 PM–4:00 PM and Istanbul 7:00 AM–10:00 AM locally.
What is the time difference between Tokyo and Istanbul?
Tokyo is currently UTC+09:00 and Istanbul is UTC+03:00, a difference of 6 hours. The exact gap can shift by one hour when one city switches to or from Daylight Saving Time.
Should we shift the meeting if one city changes Daylight Saving Time?
Yes — when only one of the two cities observes DST, the overlap window moves by an hour. Re-check this page in the weeks around March/April and October/November and adjust your standing meeting accordingly. The 24-hour grid below always reflects the current correct offset.
Can I schedule a daily standup that works for both Tokyo and Istanbul?
It's tight but doable. A meeting early in Tokyo's day (around 8–9am) catches the other city at the end of theirs. Rotate the burden monthly to keep it fair.
