GMT to Auckland Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Greenwich Mean Time and Auckland don't overlap on the same weekday. Auckland is 12 hours ahead of Greenwich Mean Time.

With some flexibility, there are two workable windows outside standard hours, depending on which side takes the early or late slot:

• 7 AM–8 AM in Greenwich Mean Time (7 PM–8 PM in Auckland) — suggest 7:00 AM Greenwich Mean Time (7:00 PM Auckland).
• 7 PM–8 PM in Greenwich Mean Time (7 AM–8 AM the next day in Auckland) — suggest 7:00 PM Greenwich Mean Time (7:00 AM Auckland).

Either is an early start or late finish for one side, but workable for a one-off meeting.

Greenwich Mean Time is also known as GMT, or BST. To call United Kingdom, dial +44.

Auckland uses New Zealand Time (NZST, or NZDT). To call New Zealand, dial +64.

Auckland is approximately 11,400 miles north of Greenwich Mean Time.

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

Greenwich Mean Time: next transition on Sunday, October 25, 2026.

Auckland: next transition on Sunday, April 4, 2027.

Greenwich Mean Time and Auckland 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.
