Christchurch to London Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Christchurch and London don't overlap on the same weekday. London is 11 hours behind Christchurch.

With some flexibility, there’s a workable window outside standard hours:

• 6 PM–8 PM in Christchurch (7 AM–9 AM in London) — suggest 7:00 PM Christchurch (8:00 AM London).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

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

London uses Greenwich Mean Time (GMT, or BST). To call United Kingdom, dial +44.

London is approximately 11,800 miles northwest of Christchurch.

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

Christchurch: next transition on Sunday, September 27, 2026.

London: next transition on Sunday, October 25, 2026.

Christchurch and London 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.
