When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Hawaii Time and Afghanistan Time don't overlap on the same weekday. Afghanistan Time is 15 hours ahead of Hawaii Time.
With some flexibility, there’s a workable window outside standard hours:
- 5 PM–8 PM in Hawaii Time (7 AM–10 AM the next day in Afghanistan Time) — suggest 6:00 PM Hawaii Time (8:30 AM Afghanistan Time).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
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.
