ACST to NST Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Australian Central Time and Newfoundland Time don't overlap on the same weekday. Newfoundland Time is 12 hours behind Australian Central Time.

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

• 7 PM–8 PM in Australian Central Time (7 AM–8 AM in Newfoundland Time) — suggest 7:00 PM Australian Central Time (7:00 AM Newfoundland Time).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

Australian Central Time is also known as ACST, or ACDT. To call Australia, dial +61.

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

Newfoundland Time is approximately 11,400 miles northeast of Australian Central Time.

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

Australian Central Time: next transition on Sunday, October 4, 2026.

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

Australian Central Time and Newfoundland 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.
