GMT to CET converter
Convert London time to Central European Time. Paris and Berlin are one hour ahead of London all year.
Paris is 1 hour ahead of London (GMT vs CET).
London and the continent
London and the continental capitals sit one hour apart, and the gap never changes, because the UK and the EU move their clocks at the same moment: 1:00 AM UTC on the last Sunday of March and of October. When it is 9 AM in London it is 10 AM in Paris, Berlin, Rome and Madrid.
That makes this one of the easiest conversions in business. The working days overlap almost completely, apart from the first and last hour. Lunch is the only point where the two sides are not both at their desks.
A single hour is enough to cause missed calls, especially around Eurostar travel and cross-border deliveries.
Business across the Channel
London and Paris share most of the day, so meetings can happen at almost any time.
- A 9:00 AM London meeting is 10:00 AM in Paris
- A 4:00 PM London call is 5:00 PM in Berlin
- Lunch at 1:00 PM London is 2:00 PM CET
The last hour of the London afternoon is the end of the day on the continent, so late calls are best moved earlier.
Eurostar and flights
The clock change catches travellers who forget the extra hour.
- Depart St Pancras at 9:01 AM, arrive 12:17 PM CET
- Leave Paris at 6:13 PM CET, arrive about 7:30 PM London
- A flight leaving Heathrow at 8:00 AM lands in Frankfurt at about 10:45 AM CET
On the return trip you gain an hour of day.
Football and TV
Match kick-offs are listed in the local time of the host country.
- A Champions League game at 8:00 PM CET kicks off at 7:00 PM in London
- A 5:30 PM London broadcast is 6:30 PM CET
- A Saturday 12:30 PM London lunchtime match is 1:30 PM CET
UK viewers get the games an hour earlier on their clocks.
Deadlines across the Channel
A European deadline of 5:00 PM CET is 4:00 PM London, so UK applicants lose an hour. A deadline at midnight CET is 11:00 PM London the previous evening.
In the opposite direction, a UK deadline of 5:00 PM GMT is 6:00 PM CET, which gives continental users an extra hour but is after the close of many offices.
Why the one-hour gap never changes
The UK and the EU are the exceptions in this guide: they change their clocks together, at the same moment, on the same dates. The gap is therefore one hour all year, unlike pairs that involve the US, where the gap changes for a few weeks.
- Mar 28, 2027: London and Paris moves to BST (UTC+1); the gap becomes 1 hour
- Oct 31, 2027: London and Paris moves to GMT (UTC+0); the gap becomes 1 hour
The risk is not the gap, it is the label. London is on GMT in winter and BST in summer, and Paris is on CET and CEST, so the names change even though the difference is always one hour.
