When the difference changes

Argentina 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 15 hours ahead
September 26, 2026 – April 3, 2027New Zealand Time is 16 hours ahead
April 3, 2027 – September 25, 2027New Zealand Time is 15 hours ahead
September 25, 2027 – onwardsNew Zealand Time is 16 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

Argentina Time

No clock changes

Argentina Time stays on ART 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.

Scheduling between the two

There is no overlap between a nine-to-six working day in Buenos Aires and one in Auckland — the gap is too wide. A call has to sit early or late for one side. Early morning in Buenos Aires is the usual compromise, since that is late afternoon or evening in Auckland.
