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 Stockholm ferry and the clock in Helsinki
A ferry leaves Stockholm at 17:00. A flight from Berlin to Athens takes off at 08:00. The Vienna Opera Ball opens at 22:00. Anyone reading those hours in Bucharest, Sofia, Athens or Helsinki has to convert CET to EET, and the rule is short: add one hour. 17:00 CET becomes 18:00 EET, 08:00 CET becomes 09:00 EET, and 23:30 CET moves to the next day, at 00:30 EET. The one-hour distance never changes, because both regions move their clocks at the same instant, at 01:00 UTC on the last Sundays of March and October.
Below are the rule, the tables and a description of the two zones, followed by episodes from transport, music, holidays and offices. The calculation takes place in your browser, and no figure is sent to a server.
The ferry between Stockholm and Helsinki
The ticket with an extra hour
A ferry that leaves Stockholm at 17:00 CET and sails for sixteen hours reaches Helsinki at 10:00 EET the next day. The ticket shows 17:00 and 10:00, as for a trip of seventeen hours, although it takes sixteen.
The return voyage
A ferry that leaves Helsinki at 17:00 EET reaches Stockholm at 10:00 CET the next day. A “convert CET to EET” calculation made beforehand shows the hour at which passengers step onto the quay.
Flights between Berlin and Athens
The morning flight
A flight from Berlin to Athens that leaves at 08:00 CET and takes just over three hours lands at 11:10 CET, which is 12:10 EET. The ticket shows 08:00 and 12:10, as for a flight of four hours.
The return flight
A flight from Athens at 13:00 EET lands in Berlin at 15:10 CET. Whoever does a “convert CET to EET” calculation sees that it looks shorter than it is.
The border between Hungary and Romania
A new zone at the customs post
Hungary is on CET and Romania on EET. A driver who crosses the border at Oradea sets the watch forward an hour: 12:00 in Budapest is 13:00 in Bucharest.
Border-post hours
A border post open “until 22:00” on Hungarian time is open until 23:00 on Romanian time. A “convert CET to EET” calculation made beforehand shows why the hours should be written with both clocks.
The Vienna Opera Ball
The opening of the ball
The ball opens in February at 22:00 CET, which is 23:00 EET. Guests in Romania watch the broadcast late in the evening.
Midnight
The midnight quadrille, at 00:00 CET, is at 01:00 EET the next morning. Whoever wants to see it live stays up.
The Sziget festival in Budapest
The main concerts
The main concert of the evening begins at 22:00 CEST, which is 23:00 EEST. Audiences in Romania follow it live, toward midnight.
The afternoon programme
A band at 17:00 CEST plays at 18:00 EEST. A “convert CET to EET” calculation tells you at once whether you can watch it after work.
St Lucia’s Day in Stockholm
The morning procession
The candle procession of 13 December is usually broadcast from 07:00 CET, which is 08:00 EET. Finns and Romanians who watch online catch it with their first coffee.
Evening concerts
The concert at 19:00 CET is at 20:00 EET. A “convert CET to EET” calculation shows that the Swedish evening falls an hour later on the East European clock.
Trains between Vienna and Bucharest
The night train
A night train that leaves Vienna at 19:40 CET and reaches Bucharest the next day at 14:00 EET leaves, on Romanian time, at 20:40. The ticket shows 19:40 and 14:00, so it looks like a journey of eighteen hours twenty minutes, although it takes an hour less.
Border hours
Border crossings are usually announced in the time of the country the train is in. A “convert CET to EET” calculation made beforehand shows the hour at which someone is waiting for you on the platform.
How to convert CET to EET
Add one hour
CET is UTC+1 and EET is UTC+2. Eastern Europe is an hour ahead of Central Europe. Add 1 to the Central European 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 CET is 01:15 EET. 05:30 CET is 06:30 EET. 08:00 CET is 09:00 EET. 11:45 CET is 12:45 EET. 14:00 CET is 15:00 EET. 17:30 CET is 18:30 EET. 22:15 CET is 23:15 EET. 23:30 CET is 00:30 EET the next day. Only the last crosses into the next day.
With summer time
CEST against EEST is also one hour. 14:00 CEST is 15:00 EEST. The two regions move their clocks at the same instant.
Central Europe on the clock
Who keeps it
Central European time, UTC+1, is in winter the time of Germany, France, Italy, mainland Spain, Poland, Austria, Switzerland, Hungary, Sweden and Norway. In summer these countries move to UTC+2, under the name CEST.
Exceptions
Iceland, which sits on UTC+0, is not part of the zone. Russia, Belarus and Turkey have other clocks, unconnected with Central Europe.
Eastern Europe on the clock
Who keeps it
Eastern European time, UTC+2, is in winter the time of Romania, Bulgaria, Greece, Cyprus, Finland, Estonia, Latvia, Lithuania, Ukraine and Moldova. In summer these countries move to UTC+3, under the name EEST.
Egypt
Egypt is on EET but has its own summer calendar. Against Central Europe its distance can be zero, one or two hours, depending on the date.
One hour between the dials
Working hours
A Vienna office open from 09:00 to 17:00 works, on Romanian time, from 10:00 to 18:00. A Bucharest office open from 09:00 to 17:00 works from 08:00 to 16:00 on Vienna time. The two days overlap for seven hours, from 10:00 to 17:00 CET.
Who rings first
A call from Vienna at 08:30 CET rings at 09:30 EET. One from 16:30 CET rings at 17:30 EET, toward the end of the East European schedule.
The short flight
A flight from Vienna to Bucharest that leaves at 08:00 CET and takes nearly two hours lands at 10:00 CET, which is 11:00 EET. The ticket shows 08:00 and 11:00, as for a flight of three hours.
Champions League football
The evening match
A match that starts at 21:00 CET starts at 22:00 EET. Fans in Romania and Greece follow until near midnight.
The afternoon match
A league game at 15:30 CET is at 16:30 EET. A “convert CET to EET” calculation shows at once that it falls in the middle of the afternoon on the Romanian clock.
Dated examples
January
On Friday 9 January, 14:00 CET is 15:00 EET. Both zones are on standard time.
The last week of March
On Friday 27 March, 14:00 CET is 15:00 EET. On Sunday 29 March, at 01:00 UTC, both clocks advance: on Friday 3 April, 14:00 CEST is 15:00 EEST. The difference stayed at one hour.
Summer
On Friday 7 August, 14:00 CEST is 15:00 EEST. Both are on summer time.
Autumn
On Friday 30 October, 14:00 CET is 15:00 EET, after the simultaneous return to standard time on 25 October. On Friday 18 December, 14:00 CET is 15:00 EET.
Egypt and its summer calendar
When Cairo shares Berlin’s hour
Egypt goes onto summer time on the last Friday of April and returns on the last Thursday of October. In 2026, between 29 March and 23 April, Central Europe is already on CEST (UTC+2) while Egypt is still on EET (UTC+2): Cairo and Berlin show the same hour. Between 25 and 29 October, Central Europe is on CET (UTC+1) and Egypt still on EEST (UTC+3): the distance is two hours.
How to read it
For the rest of the year Cairo is an hour ahead of Berlin. A “convert CET to EET” calculation for Egypt has to be made with the date in view, not just the name of the zone.
Developer teams between Vienna and Bucharest
The morning meeting
A team with members in Vienna and Bucharest meets at 09:00 CET, which is 10:00 EET. For the Viennese it is the start of the day, for the Bucharesters the second working hour.
What stays in writing
Work that ends at 17:00 CET reaches Bucharest at 18:00 EET, after working hours. A written handover keeps the thread.
More European clocks, counted from Vienna
How many hours to add
Relative to Vienna, Bucharest, Athens, Sofia and Helsinki are 1 hour ahead, Moscow 2 in winter, and London and Lisbon 1 hour behind.
One instant, four capitals
When it is 14:00 in Vienna, it is 15:00 in Bucharest, 15:00 in Helsinki, 13:00 in London and 16:00 in Moscow. An invitation that lists them all spares the reader any convert CET to EET.
Online courses between European universities
Lecture time
A lecture at 10:00 CET is at 11:00 EET. Students in Romania start it an hour later on their own clocks than those in Austria.
Deadlines
A deadline of 23:59 CET is at 00:59 EET the next day. Whoever takes the deadline to be Romanian midnight actually has an hour less.
Concerts from Central Europe broadcast in Romania
The evening concert
A concert that begins at 20:00 CET begins at 21:00 EET. Romanian audiences watch live after dinner.
Late broadcasts
A broadcast at 22:30 CET is at 23:30 EET. A “convert CET to EET” calculation shows that the Central European evening ends an hour later on the Bucharest clock.
The Belgrade to Sofia coach
The road east
A coach that leaves Belgrade at 08:00 CET and drives for six hours reaches Sofia at 14:00 CET, which is 15:00 EET. The ticket reads 08:00 and 15:00, as for a journey of seven hours. Passengers move their watches forward somewhere after the border, and a hurried traveller who forgets misses the meeting.
The road west
A coach that leaves Sofia at 09:00 EET, which is 08:00 CET, and also drives for six hours reaches Belgrade at 15:00 EET, which is 14:00 CET. The ticket shows 09:00 and 14:00, as for a trip of five hours. A “convert CET to EET” calculation done in advance explains why one direction looks longer than the other.
Relatives at the other end
Family waiting at the end of the road read the arrival time from the ticket and have to correct it by an hour. Serbia and Bulgaria move their clocks on the same night, so the correction is the same all year round.
Clock changes: what they do to the gap
The 2026 calendar
Because CET and EET follow the same calendar, the gap of 1 hour does not move; in summer they are called CEST and EEST.
In practice
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 CET to EET.
Every hour in one table

00:00 CET corresponds to 01:00 EET. 01:00 CET corresponds to 02:00 EET. 02:00 CET corresponds to 03:00 EET. 03:00 CET corresponds to 04:00 EET. 04:00 CET corresponds to 05:00 EET. 05:00 CET corresponds to 06:00 EET. 06:00 CET corresponds to 07:00 EET. 07:00 CET corresponds to 08:00 EET. 08:00 CET corresponds to 09:00 EET. 09:00 CET corresponds to 10:00 EET. 10:00 CET corresponds to 11:00 EET. 11:00 CET corresponds to 12:00 EET. 12:00 CET corresponds to 13:00 EET. 13:00 CET corresponds to 14:00 EET. 14:00 CET corresponds to 15:00 EET. 15:00 CET corresponds to 16:00 EET. 16:00 CET corresponds to 17:00 EET. 17:00 CET corresponds to 18:00 EET. 18:00 CET corresponds to 19:00 EET. 19:00 CET corresponds to 20:00 EET. 20:00 CET corresponds to 21:00 EET. 21:00 CET corresponds to 22:00 EET. 22:00 CET corresponds to 23:00 EET. 23:00 CET corresponds to 00:00 EET (next day).
How to read it
Each row pairs one CET hour with the matching EET hour and says when the date changes. The rows follow the same rule that applies when you convert CET to EET. With a whole-hour offset the minutes are untouched; if they differ in your result, the input was misread.

The rhythm of the day in EET
Even-numbered CET hours seen from EET
06:00 CET corresponds to 07:00 EET (early morning). 08:00 CET corresponds to 09:00 EET (morning). 10:00 CET corresponds to 11:00 EET (morning). 12:00 CET corresponds to 13:00 EET (around midday). 14:00 CET corresponds to 15:00 EET (afternoon). 16:00 CET corresponds to 17:00 EET (afternoon). 18:00 CET corresponds to 19:00 EET (evening). 20:00 CET corresponds to 21:00 EET (evening). 22:00 CET corresponds to 23:00 EET (night).
Reading the labels
For every second hour of the CET day the list gives the EET time and a word for the part of the day there. Use it to decide whether a request to convert CET to EET gives a polite hour.
Checklist: how to convert CET to EET
Before the sum
Confirm the zones
A schedule in Warsaw or Madrid in July says CEST, not CET, though the country is the same. Cairo, Athens, Bucharest and Helsinki share the EET offset, though Egypt follows its own summer calendar.
Use a 24-hour clock
Write 4:30 p.m. as 16:30 and 12:00 a.m. as 00:00 before you start. For example, 09:15 CET becomes 10:15 EET.
Finishing
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
An evening check: 22:40 CET gives 23:40 EET.
Common slips when you convert CET to EET
Subtracting instead of adding
Because EET runs ahead of CET, the result must be a later clock reading. An earlier one points to a subtraction.
Losing the date
Anything on the CET clock from 23:00 lands on the next date. Forgetting to move the date leaves the result 24 hours wrong.
Mixing up labels in summer
Summer renames the zones CEST and EEST without moving them apart. The new names do not change the gap, so leave the sum alone.
Confusing the abbreviation
Romania is not on CET: it uses Eastern European Time, one hour ahead. A Romanian schedule in July says EEST (UTC+3), not EET.
