When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Ottawa and Kuala Lumpur don't overlap on the same weekday. Kuala Lumpur is 12 hours ahead of Ottawa.
With some flexibility, there are two workable windows outside standard hours, depending on which side takes the early or late slot:
- 7 AM–8 AM in Ottawa (7 PM–8 PM in Kuala Lumpur) — suggest 7:00 AM Ottawa (7:00 PM Kuala Lumpur).
- 7 PM–8 PM in Ottawa (7 AM–8 AM the next day in Kuala Lumpur) — suggest 7:00 PM Ottawa (7:00 AM Kuala Lumpur).
Either is an early start or late finish for one side, but workable for a one-off meeting.
This window may shift by an hour during daylight saving time.
Public holidays in 2026
National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
