NST to LHST Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Newfoundland Time and Lord Howe Time don't overlap on the same weekday. Lord Howe Time is 13 hours ahead of Newfoundland Time.

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

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

Newfoundland Time is also known as NST, or NDT. To call Canada, dial +1.

Lord Howe Time is also known as LHST, or LHDT. To call Australia, dial +61.

Lord Howe Time is approximately 10,450 miles west of Newfoundland Time.

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

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

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

Newfoundland 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.
