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:

Now – September 26, 2026New Zealand Time is 2 hours 30 minutes ahead
September 26, 2026 – October 4, 2026New Zealand Time is 3 hours 30 minutes ahead
October 4, 2026 – September 25, 2027New Zealand Time is 2 hours 30 minutes ahead
September 25, 2027 – October 3, 2027New Zealand Time is 3 hours 30 minutes ahead
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.
