London to Christchurch Converter

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

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

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

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

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

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

Christchurch is approximately 11,800 miles northeast of London.

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

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

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

London and Christchurch 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.
