What is NZST in HST?

Hawaii Standard Time is 23 hours behind

New Zealand Time is on UTC+13:00 and Hawaii Standard Time is on UTC−10:00 right now. New Zealand Time is on daylight saving, so its clocks read NZDT. The gap changes during the year — see below.

When the difference changes

New Zealand Time and Hawaii 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:

  1. Now – April 4, 2027Hawaii Standard Time is 23 hours behind
  2. April 4, 2027 – September 26, 2027Hawaii Standard Time is 22 hours behind
  3. September 26, 2027 – onwardsHawaii Standard Time is 23 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, April 4, 2027

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

Hawaii Standard Time

No clock changes

Hawaii Standard Time stays on HST all year, so its offset from UTC never moves.

Scheduling between the two

Working hours overlap from 9:00 am to 5:00 pm NZDT, which is 10:00 am to 6:00 pm HST. Anything inside that window falls in the normal working day at both ends.

Hawaii Standard Time (HST) is used in all of Hawaii, which does not observe daylight saving
