About
Working across 7 hours of time difference
At 7 hours apart, Istanbul and Sydney have a narrow overlap window — usually one or two hours where both teams are reasonably awake and at work. Treat meetings as a shared cost: alternate between early-morning (Istanbul) and late-evening (Sydney) slots so neither side bears the inconvenience permanently.
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 Istanbul and Sydney 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 Istanbul and Sydney?
Best overlap: 7:00 AM–10:00 AM Istanbul time (2/2 zones in business hours). The strongest business-hour overlap is UTC 4:00–8:00, which is Istanbul 7:00 AM–10:00 AM and Sydney 2:00 PM–5:00 PM locally.
What is the time difference between Istanbul and Sydney?
Istanbul is currently UTC+03:00 and Sydney is UTC+10:00, a difference of 7 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 Istanbul and Sydney?
It's tight but doable. A meeting early in Sydney's day (around 8–9am) catches the other city at the end of theirs. Rotate the burden monthly to keep it fair.
