What is the normal time difference between London and Helsinki?

Helsinki is usually 2 hours ahead of London. London observes GMT (UTC+0) in winter and BST (UTC+1) in summer; Helsinki observes EET (UTC+2) in winter and EEST (UTC+3) in summer. Because both countries shift their clocks on the same last Sunday in March and October, the gap stays at 2 hours year-round.

Is there ever a time when London and Helsinki are only 1 hour apart?

Briefly, yes — if the two countries happen to change their clocks on different days in the same year, the offset can temporarily drop to 1 hour. Under current EU-coordinated rules this does not happen, and the standard 2-hour gap is maintained throughout the year.

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 Finland (Helsinki) change its clocks?

Finland moves clocks forward on the last Sunday in March at 03:00 EET (becoming EEST, UTC+3) and back on the last Sunday in October at 04:00 EEST (returning to EET, UTC+2). This matches the UK change day exactly.

What are good meeting times for both London and Helsinki?

With a 2-hour gap, good overlap windows are 09:00–16:00 London (11:00–18:00 Helsinki). Earlier Helsinki mornings (09:00–11:00) fall outside London business hours. The meeting overlap finder on this page highlights the shared 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.
