What is the normal time difference between London and Auckland?

The offset varies by season because both cities observe Daylight Saving Time at opposite times of year. It ranges from +11 hours (London BST UTC+1, Auckland NZST UTC+12 — UK summer) to +13 hours (London GMT UTC+0, Auckland NZDT UTC+13 — UK winter). The most common values are +11 and +13 hours; +12 occurs briefly during shoulder months. This tool always shows the live offset.

When is Auckland ahead by 13 hours?

When London is on GMT (UTC+0) and Auckland is on NZDT (UTC+13) — roughly from late October through late March (UK autumn and winter). This is when the gap is at its largest.

When is Auckland ahead by only 11 hours?

When London is on BST (UTC+1) and Auckland is on NZST (UTC+12) — roughly from April to September (UK summer, New Zealand winter). This is the shortest gap of the year.

When does New Zealand DST start and end?

New Zealand moves clocks forward by 1 hour on the last Sunday in September (switching from NZST UTC+12 to NZDT UTC+13) and back on the first Sunday in April.

What are good meeting times for both London and Auckland?

Strict 09:00–18:00 business hours do not overlap. An off-hours compromise is typically London 07:00–09:00 (Auckland 19:00–21:00 or 20:00–22:00 depending on DST); the table below highlights only strict business-hour overlap.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

Summary

This tool displays the live current time in both London (Europe/London — GMT in winter, BST in summer) and Auckland (Pacific/Auckland — NZST UTC+12 in winter, NZDT UTC+13 in summer) side by side. The exact offset is calculated automatically and adjusts whenever either city transitions for Daylight Saving Time — note that New Zealand DST runs opposite to the UK (southern hemisphere summer is UK winter). Use it to schedule calls between the UK and New Zealand, coordinate remote teams, or check whether an Auckland colleague is still in the office.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Europe/London time using the IANA timezone database built into modern browsers.
The same moment is converted to Pacific/Auckland time.
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — London time, Auckland time, and the offset — refresh every second.
DST transitions for both cities are handled automatically; Auckland observes NZDT (UTC+13) in the New Zealand summer (roughly September–April), while London observes BST in its own summer (March–October).
