What is the normal time difference between London and Athens?

Athens is usually 2 hours ahead of London. London observes GMT (UTC+0) in winter and BST (UTC+1) in summer; Athens observes EET (UTC+2) in winter and EEST (UTC+3) in summer. Because both cities 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 Athens are only 1 hour apart?

Normally no — both countries follow the EU/European clock-change schedule (last Sunday in March and last Sunday in October), so the 2-hour gap is maintained throughout the year. This tool shows the real-time 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 Greece (Athens) change its clocks?

Greece 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 Athens?

Because Athens is 2 hours ahead, a London 09:00–15:00 window maps to 11:00–17:00 Athens — both within standard business hours. 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.
