When the difference changes

New Zealand Time and Japan Standard 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 27, 2026Japan Standard Time is 3 hours behind
September 27, 2026 – April 4, 2027Japan Standard Time is 4 hours behind
April 4, 2027 – September 26, 2027Japan Standard Time is 3 hours behind
September 26, 2027 – onwardsJapan Standard Time is 4 hours behind

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

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.

Japan Standard Time

No clock changes

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