When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in New York and Phnom Penh don't overlap on the same weekday. Phnom Penh is 11 hours ahead of New York.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–9 AM in New York (6 PM–8 PM in Phnom Penh) — suggest 8:00 AM New York (7:00 PM Phnom Penh).
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.
