When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Central Time and Lord Howe Time don't overlap on the same weekday. Lord Howe Time is 16 hours ahead of Central Time.

With some flexibility, there’s a workable window outside standard hours:

  • 4 PM–8 PM in Central Time (7 AM–11 AM the next day in Lord Howe Time) — suggest 6:00 PM Central Time (9:30 AM 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.

Daylight saving time

Both zones observe daylight saving time, but they transition on different dates.

Central Time: next transition on Sunday, November 1, 2026.

Lord Howe Time: next transition on Sunday, October 4, 2026.

Central Time and Lord Howe Time are in opposite hemispheres, so their clocks change in opposite directions about six months apart — one springs forward while the other falls back. The offset between them therefore shifts twice a year and can swing by up to two hours across the seasons, more than a typical same-hemisphere pair. Recurring meetings will need re-checking after each transition.

See the daylight saving time page for transition dates across every time zone.
