When the difference changes

Japan Standard 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 3 hours ahead
September 26, 2026 – April 3, 2027New Zealand Time is 4 hours ahead
April 3, 2027 – September 25, 2027New Zealand Time is 3 hours ahead
September 25, 2027 – onwardsNew Zealand Time is 4 hours 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.

Daylight saving

Japan Standard Time

No clock changes

Japan Standard Time stays on JST all year, so its offset from UTC never moves.

New Zealand Time

Sunday, September 27, 2026

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on NZDT after that.
