CET vs GMT — Frankfurt to London

CET (UTC+1) — Central European Time, covering Germany, France, Italy, Spain, Netherlands, and ~20 more countries. Shifts to CEST (UTC+2) in summer.

GMT (UTC+0) — UK winter time. London uses BST (UTC+1) from late March to late October.

With only 1 hour between them, CET and GMT cities share nearly identical working hours. The gap stays at 1 hour year-round, making Europe–UK scheduling the simplest of all cross-timezone combinations.

Frequently Asked Questions

How many hours is CET ahead of GMT?

CET (Central European Time, UTC+1) is 1 hour ahead of GMT (UTC+0). This 1-hour gap is consistent in winter. In summer, both regions observe daylight saving: CEST (UTC+2) is 1 hour ahead of BST (UTC+1), keeping the same 1-hour difference. The gap stays at 1 hour throughout the year.

What is 9 AM CET in GMT?

9:00 AM CET is 8:00 AM GMT. Since the gap is only 1 hour, business hours overlap almost completely. A 9:00 AM Frankfurt meeting equals 8:00 AM London, and a 5:00 PM Berlin end of day equals 4:00 PM London.

Does the CET to GMT gap change in summer?

No. The 1-hour gap stays constant throughout the year. In winter, CET (UTC+1) is 1 hour ahead of GMT (UTC+0). In summer, CEST (UTC+2) is 1 hour ahead of BST (UTC+1). Both regions observe DST simultaneously, so the offset between them never changes.

What is the difference between CET and GMT for business?

The 1-hour difference means European CET cities (Frankfurt, Berlin, Paris, Amsterdam) are always just 1 hour ahead of London. This makes scheduling easy — any working hour in London is a working hour in Frankfurt. The London Stock Exchange and Frankfurt/Euronext exchanges have significant daily overlap.
