When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Coordinated Universal Time and Lord Howe Time don't overlap on the same weekday. Lord Howe Time is 11 hours ahead of Coordinated Universal Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–10 AM in Coordinated Universal Time (5 PM–8 PM in Lord Howe Time) — suggest 8:00 AM Coordinated Universal Time (6:30 PM Lord Howe 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.
