When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Western Indonesia Time and Central Time don't overlap on the same weekday. Central Time is 12 hours behind Western Indonesia Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 PM–8 PM in Western Indonesia Time (7 AM–8 AM in Central Time) — suggest 7:00 PM Western Indonesia Time (7:00 AM Central Time).
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.
