About NZST

New Zealand Standard Time (NZST) is UTC+12. It is used in Auckland and Wellington in the southern winter.

New Zealand Standard Time is UTC+12, the furthest ahead of the commonly used abbreviations, moving to NZDT at UTC+13 from late September to early April. New Zealand is where the date changes first for most of the world's working population, which is why release schedules and financial rollovers are often expressed relative to it. Chatham Islands time, at UTC+12:45, is one of only three quarter-hour offsets in use anywhere.

About NZDT

New Zealand Daylight Time (NZDT) is UTC+13. It is used in New Zealand from late September to early April.

New Zealand Daylight Time is UTC+13, one of the few offsets past twelve hours and therefore a full calendar day ahead of most of the Americas. New Zealand's summer is the northern hemisphere's winter, so NZDT applies over Christmas — the opposite of every northern daylight-saving abbreviation, and a common mistake in end-of-year scheduling.

Does this gap change with the seasons?

Neither NZST nor NZDT shifts with the seasons, so this 1-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.

This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
