Istanbul is on UTC+3 all year and does not observe daylight saving, so the gap changes only when your clocks do. The table converts a 09:00–18:00 Istanbul working day to local time and compares it with a 09:00–17:00 local day.
| City | Hours behind Istanbul (daylight / standard) | Istanbul 09:00–18:00, local time (daylight / standard) | Overlap with your 09:00–17:00 |
| Halifax | 6 / 7 | 03:00–12:00 / 02:00–11:00 | 09:00–12:00 in summer, 09:00–11:00 in winter |
| Toronto, Ottawa, Montreal | 7 / 8 | 02:00–11:00 / 01:00–10:00 | 09:00–11:00 in summer, 09:00–10:00 in winter |
| Winnipeg | 8 / 9 | 01:00–10:00 / 00:00–09:00 | 09:00–10:00 in summer. None in winter, when an 08:00 call is 17:00 in Istanbul |
| Regina, Saskatoon | 9 all year | 00:00–09:00 | None. An 08:00 call is 17:00 in Istanbul |
| Calgary, Edmonton | 9 / 10 | 00:00–09:00 / 23:00 (previous day)–08:00 | None. 08:00 local is 17:00 in Istanbul in summer and 18:00 in winter |
| Vancouver | 10 / 11 | 23:00 (previous day)–08:00 / 22:00 (previous day)–07:00 | None. 08:00 local is 18:00 in Istanbul in summer and 19:00 in winter |
St. John’s is half an hour ahead of Halifax, which adds thirty minutes to the Atlantic overlap.
Reading the table
Atlantic and Eastern Canada have a usable live window every morning. A standing call at 09:00 or 09:30 works all year, and the remainder of your day is covered by written questions that are answered before you next sit down.
The Prairies and the West have no overlap inside standard hours. Live calls mean an 08:00 start for you and a late finish for us, so they are scheduled in advance and kept to one or two a week. The project itself runs asynchronously through a written scope, written progress updates, recorded walkthroughs where they help, and a staging environment you can open whenever you like. Our working process is built around that written record, which is why it holds up at a distance.
The time difference has one useful effect across the whole country. Feedback written during your afternoon is picked up at the start of the next Istanbul day, so fixes are frequently on staging before your morning begins.
