When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Hawaii Time and Gulf Standard Time don't overlap on the same weekday. Gulf Standard Time is 14 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 Gulf Standard Time) — suggest 6:00 PM Hawaii Time (8:00 AM Gulf Standard 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.
