When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Kuala Lumpur and Ottawa don't overlap on the same weekday. Ottawa is 12 hours behind Kuala Lumpur.
With some flexibility, there’s a workable window outside standard hours:
- 7 PM–8 PM in Kuala Lumpur (7 AM–8 AM in Ottawa) — suggest 7:00 PM Kuala Lumpur (7:00 AM Ottawa).
This means an early start or late finish for one side, but it’s a reasonable slot 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.
