Best time for work calls
If you are scheduling a call between Ottawa and San Francisco, the overlap window is limited to typical business hours. When it is 12 pm in Ottawa it is 9 am in San Francisco — a workable window for scheduling. The latest reasonable overlap is around 5 pm in Ottawa (2 pm in San Francisco). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
Ottawa and San Francisco have a comfortable window for a family call — no awkward alarms required. Ottawa is 3 hours ahead of San Francisco, which gives you 4 hours of genuine overlap when both sides are free.
