What is the normal time difference between London and Zurich?

Zurich is usually 1 hour ahead of London. London observes GMT (UTC+0) in winter and BST (UTC+1) in summer; Zurich observes CET (UTC+1) in winter and CEST (UTC+2) in summer. Because both cities shift their clocks on the same last Sunday in March and October, the gap stays at 1 hour year-round.

Is there ever a time when London and Zurich are the same time?

No. The UK and Switzerland change their clocks on the same schedule (last Sunday in March and last Sunday in October), so the 1-hour gap is maintained throughout the year. This tool shows the real offset live.

When does the UK change its clocks?

The UK moves clocks forward on the last Sunday in March at 01:00 GMT (becoming BST, UTC+1) and back on the last Sunday in October at 02:00 BST (returning to GMT, UTC+0).

When does Switzerland (Zurich) change its clocks?

Switzerland moves clocks forward on the last Sunday in March at 02:00 CET (becoming CEST, UTC+2) and back on the last Sunday in October at 03:00 CEST (returning to CET, UTC+1). This matches the UK change day exactly.

What are good meeting times for both London and Zurich?

Because the gap is only 1 hour, almost all standard business hours overlap. A 09:00–17:00 London window corresponds to 10:00–18:00 Zurich. The meeting overlap finder on this page highlights those windows automatically.

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.
