What is ACST in NZST?

New Zealand Time is 2 hours 30 minutes ahead

Australian Central Time is on UTC+10:30 and New Zealand Time is on UTC+13:00 right now. Both are on daylight saving, so their clocks read ACDT and NZDT. The gap changes during the year — see below.

When the difference changes

Australian Central Time and New Zealand Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – September 25, 2027New Zealand Time is 2 hours 30 minutes ahead
  2. September 25, 2027 – October 3, 2027New Zealand Time is 3 hours 30 minutes ahead
  3. October 3, 2027 – onwardsNew Zealand Time is 2 hours 30 minutes ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Scheduling between the two

Working hours overlap from 9:00 am to 4:00 pm ACDT, which is 11:30 am to 6:30 pm NZDT. Anything inside that window falls in the normal working day at both ends.

Australian Central Time (ACDT) is used in South Australia and the Northern Territory, on a half-hour offset from the east coast
