Where these units come from
Until the middle of the nineteenth century every town kept its own noon, set by the sun overhead, and nobody minded that the next town was four minutes behind. Railways ended that: a timetable cannot be written for a hundred local noons. Britain put its railways on Greenwich time in 1847, and in 1884 the International Meridian Conference in Washington chose Greenwich as the prime meridian and sketched the twenty-four-hour scheme we still use. Greenwich Mean Time was the world's reference until 1972, when Coordinated Universal Time replaced it: UTC is kept by atomic clocks and tied back to the turning Earth by leap seconds. The abbreviations on this page name standard time — the winter setting — which is why each one is a fixed number of hours rather than something that drifts through the year.
Where you meet them
A time zone becomes real the moment two people in different places have to agree on one moment: a call between offices, a flight that lands before it took off, a market that opens while you are asleep, a deadline written in somebody else's afternoon. Server logs, train and flight schedules and anything stamped with a time are kept in UTC precisely so that the question can always be settled, no matter whose clock was on the wall.
Questions people ask
What about summer time?
The offsets here are standard-time offsets, the ones a zone keeps in winter. Where summer time is observed, the same places move one hour further on for part of the year and take a different name: Central European Time becomes Central European Summer Time, Eastern Standard Time becomes Eastern Daylight Time. The switching dates are not the same in every country, and the two hemispheres change in opposite months, so for a date inside a summer-time period add an hour to whichever side observes it.
Why isn't every difference a whole number of hours?
Because offsets are decided by governments, not by geometry. India is half an hour off the hour, at UTC+05:30; Nepal is three quarters, at UTC+05:45; the Chatham Islands are at UTC+12:45. Any of these can be changed by law, and several countries have moved their offset within living memory.
Is the answer exact?
Where both units are defined in terms of one another by whole numbers, yes — the page says so above the figure, and the only rounding is in how many digits are shown. Where the ratio has no finite decimal, the page shows twelve significant digits and says the relation is approximate rather than pretending otherwise.

The Wimbledon final and the clock in Vienna
The men's final at Wimbledon is played on Sunday at 14:00. Glastonbury's biggest name walks on stage at 22:00. The first Eurostar out of London departs at 08:01. A viewer in Berlin, Vienna, Paris or Warsaw who wants those moments on a local dial will convert WET to CET, and here the sum is the shortest in Europe: put one hour on. 14:00 WET reads 15:00 CET, 22:00 WET reads 23:00 CET, and 23:30 WET spills into the following day as 00:30 CET. The single hour is permanent, since Britain, Ireland, Portugal and the Central European countries all change their clocks at the very same moment, 01:00 UTC on the last Sundays of March and October.
After the rule come the lookup tables and a sketch of each zone, then stories from sport, festivals, railways, television and conference calendars. All calculations stay in your browser and nothing is transmitted.
The Wimbledon final
The first serve
The men’s final begins at 14:00 BST, which is 15:00 CEST. Spectators in Germany and Austria watch live in the afternoon, and the match usually ends toward 18:00 CEST.
The women’s final
Saturday’s final begins at 14:00 BST, which is 15:00 CEST. A “convert WET to CET” calculation shows at once that the European hour is always one higher.
The Glastonbury festival
The main stage
The biggest artists take the main stage around 22:00 BST, which is 23:00 CEST. European audiences watch live late in the evening.
Concerts after midnight
A concert that starts at 00:30 BST starts at 01:30 CEST. Whoever wants to see it stays up or watches the recording.
Eurostar from London
The morning train
A train that leaves London at 08:01 GMT reaches Paris at 11:17 CET. The ticket shows 08:01 and 11:17, as for a journey of three and a quarter hours, although the train travels for two and a quarter.
The evening service
A train from London at 17:30 GMT reaches Paris at 20:46 CET. A “convert WET to CET” calculation made beforehand shows the hour at which someone is waiting for you at the station.
The Edinburgh Military Tattoo
The evening show
The show at the castle begins at 21:00 BST, which is 22:00 CEST. European audiences watch the broadcast late in the evening.
The afternoon performance
A performance broadcast at 15:00 BST is at 16:00 CEST. For Central Europe it is an afternoon transmission.
The Dublin marathon
The morning start
The start is on the last Monday of October at 09:00 local time. In 2026 that date falls after the clocks change, so local time is GMT and the European hour is 10:00 CET.
The finish
The winners arrive after almost two hours, around 11:10 GMT, which is 12:10 CET. A “convert WET to CET” calculation tells you at once whether you can watch before lunch.
New Year’s Eve in London
Fireworks on the Thames
The fireworks at midnight, at 00:00 GMT, are at 01:00 CET on the morning of 1 January. Europeans in the middle of the continent watch them an hour after celebrating their own New Year.
The evening programme
The concert on the riverbank starts at 20:00 GMT, which is 21:00 CET. A “convert WET to CET” calculation made in good time shows whether the broadcast catches dinner.
Web Summit in Lisbon
The first day
The opening talks in November begin at 09:00 WET, which is 10:00 CET. Participants in Germany and Poland join live in mid-morning.
Meetings with investors
Afternoon meetings from 15:00 WET are at 16:00 CET. A “convert WET to CET” calculation shows at once that the Portuguese programme is seen in Central Europe an hour later.
How to convert WET to CET, in plain terms
Add one hour
WET is UTC+0 and CET is UTC+1. Central Europe is an hour ahead of London, Dublin and Lisbon. Add 1 to the London time on a 24-hour clock. If the total passes 24:00, subtract 24 and go to the next day.
Eight values to remember
00:15 WET is 01:15 CET. 05:30 WET is 06:30 CET. 08:00 WET is 09:00 CET. 11:45 WET is 12:45 CET. 14:00 WET is 15:00 CET. 17:30 WET is 18:30 CET. 22:15 WET is 23:15 CET. 23:30 WET is 00:30 CET the next day. Only the last crosses into the next day.
With summer time
WEST against CEST is also one hour. 14:00 WEST is 15:00 CEST. Both zones move their clocks at the same instant.
The central clock at a glance
Which countries
Germany, France, Italy, mainland Spain, Poland, Austria and Switzerland read UTC+1 as CET in winter and UTC+2 as CEST in summer, switching on the final Sundays of March and October at 01:00 UTC.
A note for Romania
Romanian clocks run one hour ahead of Central Europe, so a reader in Bucharest has to put two hours on a London time, not one.
The western clock at a glance
Which countries
Britain and Ireland call their winter time GMT. Mainland Portugal, Madeira, the Canaries and the Faroes call theirs WET. Iceland sits on UTC+0 all year. Apart from Iceland, every one of these places moves forward an hour in summer.
Two special cases
Reykjavik trails Central Europe by one hour in winter and two in summer. The Azores trail it by two hours throughout the year, on UTC-1 in winter and UTC+0 in summer.
One hour apart on the wall
How the offices line up
A London team working 09:00-17:00 is at its desks from 10:00 to 18:00 on Berlin time, whereas a Berlin team on the same schedule keeps 08:00-16:00 by London time. Seven hours are shared, running from 09:00 to 16:00 WET.
Which call lands well
Ringing from London at 08:30 WET reaches Berlin at 09:30 CET. A call at 16:30 WET reaches it at 17:30 CET, close to the end of the European day.
A short hop across the Channel and the Rhine
A plane that departs London at 08:00 WET and flies for nearly ninety minutes touches down in Frankfurt at 09:30 WET, which is 10:30 CET. The boarding pass shows 08:00 and 10:30, as if the flight took two and a half hours.
Evening series on British television
The Saturday programme
A dance programme broadcast on Saturday at 19:00 GMT is at 20:00 CET. Viewers in Germany and Austria watch it live at dinner time.
Sunday series
A series broadcast at 21:00 GMT is at 22:00 CET. A “convert WET to CET” calculation shows that the British evening ends an hour later on the European clock.
The same London hour on four Tuesdays
Mid-winter
Tuesday 13 January: 14:00 GMT corresponds to 15:00 CET, with both regions on winter time.
Around the spring change
Tuesday 24 March still gives 14:00 GMT against 15:00 CET. After both blocs advance their clocks on Sunday 29 March at 01:00 UTC, Tuesday 31 March gives 14:00 BST against 15:00 CEST: no change to the gap.
In July
Tuesday 21 July pairs 14:00 BST with 15:00 CEST, because everyone is on summer time.
Back on winter time
Tuesday 27 October, two days after the shared return to standard time, pairs 14:00 GMT with 15:00 CET. Tuesday 8 December gives the same answer.
Reykjavik and Ponta Delgada break the pattern
Iceland
Icelanders never touch their clocks. When Reykjavik reads 13:00, Berlin reads 14:00 in winter and 15:00 in summer, so a “convert WET to CET” calculation that assumes a single hour will be wrong for Iceland during half the year.
The Azores
With UTC-1 in winter and UTC+0 in summer, the Azores are two hours behind Central Europe whatever the month: 13:00 in Ponta Delgada is 15:00 CET.
A split team in London and Berlin
The daily stand-up
A group spread across London and Berlin meets at 09:00 WET, which is 10:00 CET. The Londoners are just starting; the Berliners have already done an hour.
Work handed over in writing
A task wrapped up at 17:00 WET lands in Berlin at 18:00 CET, once the German day is over. A written note carries the context to the next morning.
More European clocks, counted from London
How many hours to add
Relative to London, Berlin is 1 hour ahead, Athens and Bucharest 2, Moscow in winter 3. Reykjavik reads the same in winter and an hour behind in summer. The Azores are an hour behind.
One instant, four capitals
When it is 12:00 in London, it is 13:00 in Berlin, 14:00 in Athens and 15:00 in Moscow. Whoever writes the hours in the invitation spares the guests a “convert WET to CET” calculation.
Shared seminars across European campuses
Start times
A seminar timetabled for 09:00 WET begins at 10:00 CET. German students begin an hour later on their own watches than British students do.
Submission cut-offs
A cut-off of 23:59 WET falls at 00:59 CET on the following day. Anyone who treats it as European midnight misjudges it by an hour.
Radio broadcasts from the BBC
The morning programme
A morning programme broadcast from 06:00 to 09:00 GMT is from 07:00 to 10:00 CET. Listeners in Central Europe catch it on the way to work.
The evening bulletin
The 18:00 GMT bulletin is at 19:00 CET. A “convert WET to CET” calculation shows at once that it falls, in Central Europe, at dinner time.
The Dover to Calais ferry
The morning crossing
A ferry that leaves Dover at 08:00 WET and sails for about ninety minutes reaches Calais at 09:30 WET, which is 10:30 CET. The ticket reads 08:00 and 10:30, as for a trip of two and a half hours, although the sea took only an hour and a half.
The afternoon return
A ferry that leaves Calais at 14:00 CET, which is 13:00 WET, reaches Dover at 14:30 WET, which is 15:30 CET. A “convert WET to CET” calculation done when you book explains why the return looks shorter on paper than the outward leg. Passengers see the same effect on board clocks, which are reset to the destination country when the ship leaves harbour.
Lorries and timesheets
Drivers who keep logbooks in French and British time write each end of the journey on the local clock. The dispatcher at home then adds or removes exactly one hour, depending on the direction the lorry travelled.
Clock changes: what they do to the gap
Period by period
Both zones change their clocks together, so WET and CET stay 1 hour apart in every season; only the labels change, to WEST and CEST in summer.
What to do about it
In 2026 the European clocks change on 29 March and 25 October, and the American ones on 8 March and 1 November. Nothing about the sum changes with the season when you convert WET to CET.

Using the table
Find the WET hour you need and read off the CET hour beside it. The rows come from the arithmetic behind each request to convert WET to CET. Minutes are not affected here. A different minute figure in an answer is a sign of a slip.

Why it helps
Many meetings, broadcasts and scheduled jobs start at half past the hour. This table gives the CET time for each of them at a glance, which saves you a second calculation.

Observation
Real schedules are rarely on the hour, so here are ten with awkward minutes. With a whole-hour offset the minutes are untouched; if they differ in your result, the input was misread.

WET hours and the day in CET
06:00 WET = 07:00 CET (early morning). 08:00 WET = 09:00 CET (morning). 10:00 WET = 11:00 CET (morning). 12:00 WET = 13:00 CET (around midday). 14:00 WET = 15:00 CET (afternoon). 16:00 WET = 17:00 CET (afternoon). 18:00 WET = 19:00 CET (evening). 20:00 WET = 21:00 CET (evening). 22:00 WET = 23:00 CET (night).
A practical use
The list pairs a WET hour with its CET time and a plain word for the time of day. It tells you at once whether the person you call has had breakfast or gone to bed.
A quick routine to convert WET to CET
Preparation
Confirm the zones
Iceland shares the offset of WET all year but has no summer time, unlike Portugal. CET is the winter name only: from late March to late October most of its countries use CEST, one hour ahead.
Use a 24-hour clock
The 24-hour clock avoids a.m. and p.m. slips, so rewrite 4:30 p.m. as 16:30 before anything else. For example, 09:15 WET becomes 10:15 CET.
Then
The operation
Add 1 hour. If the result passes midnight, correct the date: readings from 23:00 fall on the next date.
A second example
Late in the evening, 22:40 WET becomes 23:40 CET.
Mistakes when you convert WET to CET
Subtracting instead of adding
CET is in front of WET: expect a bigger number, not a smaller one.
Losing the date
A WET time from 23:00 moves to the next date. If the date stays put, the answer is a full day out.
Mixing up labels in summer
In summer the labels change to WEST and CEST, but the gap between the two clocks does not. The new names do not change the gap, so leave the sum alone.
Confusing the abbreviation
The Azores are not on WET: they sit one hour behind mainland Portugal. Romania is not on CET: it uses Eastern European Time, one hour ahead.
Frequently asked questions
By how much do WET and CET differ?
1 hour, and CET is ahead of WET.
Which sum applies when I convert WET to CET?
Add 1 hour to the WET time, then fix the date if the result passes midnight.
How much is 21:45 WET in CET?
22:45 CET.
Is the gap the same in every month?
Yes, it is the same in every month.
Is my input stored or uploaded?
No. Nothing leaves the page.
