UTC to NZST

About Coordinated Universal Time

UTC never shifts. It is the reference every other zone is defined against, which is why logs, flight schedules and protocol timestamps use it. GMT is the same clock for every civil purpose, so a query for one is answered by the other.

Cities on this clock: Reykjavik, Accra, Abidjan, Dakar.

Watch out: GMT is also used loosely to mean "UK time", and those are not the same thing for seven months of the year — the United Kingdom moves to BST (UTC+1) while UTC stays put.

About New Zealand Time

New Zealand is UTC+12 as NZST and UTC+13 as NZDT, which makes it the first populated place to reach any given date. Its clock changes in late September and early April — the opposite half of the year to the northern zones on this site, so a gap to Europe or North America can swing by two hours rather than one.

Cities on this clock: Auckland, Wellington.

How the difference is worked out

The gap between Coordinated Universal Time and New Zealand Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 13 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.

With both zones on their own standard time — daylight saving not in force anywhere — New Zealand Time is 12 hours ahead of Coordinated Universal Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.

Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids UTC and Pacific/Auckland. Nothing is looked up on a server and nothing about your visit is recorded.
