When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Alaska Time and Western Indonesia Time don't overlap on the same weekday. Western Indonesia Time is 15 hours ahead of Alaska Time.
With some flexibility, there’s a workable window outside standard hours:
- 4 PM–8 PM in Alaska Time (7 AM–11 AM the next day in Western Indonesia Time) — suggest 6:00 PM Alaska Time (9:00 AM Western Indonesia 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.
