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