Abu Dhabi is 9 hours ahead of Ottawa
Best overlap: 8:00 AM to 9:00 AM in Ottawa is 5:00 PM to 6:00 PM in Abu Dhabi.
If you set up a recurring sync, 8:00 AM to 9:00 AM in Ottawa (5:00 PM to 6:00 PM in Abu Dhabi) is the natural home for it. There's just 1 hour of overlap here, so don't leave meetings to chance — lock 8:00 AM in Ottawa / 5:00 PM in Abu Dhabi into the calendar. Because Ottawa and Abu Dhabi don't both observe daylight saving, plan to re-check the overlap around March and November.
