NZST to EST Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in New Zealand Time and Eastern Time don't overlap on the same weekday. Eastern Time is 16 hours behind New Zealand Time.

Realistic options: hand off asynchronously, or stretch one side by an hour to catch the other team at the start or end of their day.

New Zealand Time is also known as NZST, or NZDT. To call New Zealand, dial +64.

Eastern Time is also known as EST, or EDT. To call United States, dial +1.

Both zones observe daylight saving time, but they transition on different dates.

New Zealand Time: next transition on Sunday, September 27, 2026.

Eastern Time: next transition on Sunday, November 1, 2026.

New Zealand Time and Eastern Time are in opposite hemispheres, so their clocks change in opposite directions about six months apart — one springs forward while the other falls back. The offset between them therefore shifts twice a year and can swing by up to two hours across the seasons, more than a typical same-hemisphere pair. Recurring meetings will need re-checking after each transition.

See the daylight saving time page for transition dates across every time zone.
