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.

Two hours east of Greenwich
Why this conversion comes up so often
Athens, Helsinki, Tallinn, Riga, Vilnius, Kyiv, Sofia, Bucharest, Nicosia and Cairo share a clock that is two hours ahead of Greenwich in winter. If you read a time in GMT, whether from a British broadcaster, a UK colleague or a server log, you need to convert GMT to EET to know what it means in those cities. The rule is easy: add two hours. 08:00 GMT is 10:00 EET, 16:30 GMT is 18:30 EET, and 22:15 GMT is 00:15 EET on the next date.
The sections below set out the rule, give two lookup tables, describe both zones, explain why the gap stays at two hours even though both sides change their clocks, and then work through ferries, flights, start-ups, museums and religious services. The calculation runs in your browser, and nothing you type is sent to any server.
How to convert GMT to EET
Add two hours
EET is UTC+2 and GMT is UTC+0. Add two to the GMT hour each time you convert GMT to EET. If the total reaches 24 or more, subtract 24 and advance the date by one. The last two hours of the British day move into the next date: 22:40 GMT is 00:40 EET.
Eight readings
00:30 GMT is 02:30 EET. 06:15 GMT is 08:15 EET. 09:00 GMT is 11:00 EET. 12:00 GMT is 14:00 EET. 15:45 GMT is 17:45 EET. 18:00 GMT is 20:00 EET. 21:30 GMT is 23:30 EET. 23:45 GMT is 01:45 EET the following day. Only the last row changes the date.
A plain-language version
Say “London plus two”. When London is finishing lunch at 14:00, Athens is finishing the afternoon coffee at 16:00. When London is closing the office at 17:00, Helsinki is already at 19:00 and heading for dinner.
Greenwich Mean Time in this pairing
London’s winter clock
GMT is the standard time of Britain and Ireland from the last Sunday in October to the last Sunday in March. In 2026 the British summer period runs from 29 March to 25 October, when the wall clock reads BST, UTC+1. On computers GMT is also the label for the zero-offset reference, identical to UTC.
A hidden choice
If your GMT figure comes from a machine, it is on the zero meridian all year, and in summer you must add three hours, not two, to reach EEST. If it comes from a person describing London, the wall clock in summer is BST and two hours remain the right number.
Eastern European Time
The places on EET
EET is the winter time of Greece, Cyprus, Bulgaria, Romania, Finland, Estonia, Latvia, Lithuania, Ukraine and Moldova. Egypt also uses it, with its own summer period. Well-known cities include Athens, Nicosia, Sofia, Bucharest, Helsinki, Tallinn, Riga, Vilnius, Kyiv, Chișinău and Cairo.
Summer
From the last Sunday in March to the last Sunday in October, the European members use Eastern European Summer Time, EEST, at UTC+3. In 2026 these dates are 29 March and 25 October. Egypt restored summer time in 2023 and changes its clocks on different dates: the last Friday in April and the last Thursday in October.
Two hours and the working day
The overlap
A London office open from 09:00 to 17:00 GMT is open from 11:00 to 19:00 EET. An office in Athens or Bucharest open from 09:00 to 17:00 EET is open from 07:00 to 15:00 GMT. The shared window runs from 09:00 to 15:00 GMT, which is 11:00 to 17:00 EET, six hours in which both can talk.
Mid-day habits
The Eastern lunch hour, roughly 12:30 to 14:00, falls from 10:30 to 12:00 on the Greenwich clock. A British colleague who proposes a call at 11:00 GMT may catch a counterpart on the way to the canteen. Calls at 13:00 or 14:00 GMT, which are 15:00 or 16:00 EET, are less disruptive.
By air to Athens
A flight from London that leaves at 10:00 and takes about three hours fifty minutes lands at 13:50 GMT, which is 15:50 on the Athens clock. The boarding pass lists 10:00 and 15:50, so the trip looks nearly six hours long on paper.
Why two hours is the answer all year
Joint rules
Britain and the EU members that use EET follow the same summer time rule: forward on the last Sunday in March, back on the last Sunday in October, each time at 01:00 UTC. Clocks therefore move in London and in Athens at the same instant, though not at the same local hour.
The night of 29 March 2026
At 01:00 UTC, a clock in London jumps from 01:00 to 02:00, and a clock in Athens jumps from 03:00 to 04:00. On 25 October the reverse happens: London goes from 02:00 to 01:00 and Athens from 04:00 to 03:00. The two-hour difference holds before and after.
What you need to remember
When you convert GMT to EET for a London wall clock, the answer is two hours in every month. For the zero meridian you read in a server log, it is two hours in winter and three in summer.
Helsinki and Tallinn by sea
One zone, two capitals
Ferries cross the Gulf of Finland between Helsinki and Tallinn in about two hours. Both cities are on EET, so a ferry that leaves at 10:30 arrives at 12:30 on the same clock. For a traveller who started in London, the same departure is 08:30 GMT. A British visitor who lands at Helsinki at 08:00 GMT, which is already 10:00 EET, has only half an hour before a 10:30 sailing.
Planning from a distance
Tickets are sold in local time. When you convert GMT to EET for a sailing, remember that the check-in desk closes a half hour before departure, and compute that cut-off in the same way.
Start-ups in the Baltic states
A digital society
Estonia has built a reputation for online public services and a lively start-up scene. Companies in Tallinn typically work from 09:00 to 17:00 EET, which is 07:00 to 15:00 GMT. Their British investors, working 09:00 to 17:00 GMT, can reach them only until the early afternoon.
Writing the right time
An investor meeting set for 15:00 EET starts at 13:00 GMT. A Tallinn founder who writes “three o’clock” in an e-mail to London should add the zone, because the Londoner reads three o’clock as 15:00 GMT, two hours too late.
Greek islands and flights from Athens
Hopping around the Aegean
Flights from Athens to Crete or the Cyclades leave at all hours of the day. A departure at 07:40 EET leaves at 05:40 GMT. A British traveller who joins at Athens and flies on to Santorini sees the same local time on all boarding passes, because the whole country shares one clock.
Opening hours of the Acropolis
The archaeological site opens at about 08:00 EET in winter and closes in the late afternoon. In Greenwich time that is 06:00 for the gates. A group booking at 08:30 EET starts at 06:30 GMT, which is easy to forget when the body clock is on British time.
Egypt, Cairo and the Red Sea
EET, with its own calendar
Egypt is on EET, and since 2023 it observes summer time again, from the last Friday in April to the last Thursday in October. Between 29 March and the end of April, Cairo is still on UTC+2 while Britain is on BST, so the gap shrinks to one hour in those weeks.
Flights to Sharm el-Sheikh and Hurghada
A flight leaving London at 07:00 and lasting about five hours lands at 12:00 GMT, which is 14:00 EET in winter. For divers and holidaymakers, the first full day starts at the local dawn. It is worth doing a “convert GMT to EET” calculation for the transfer to the hotel.
Orthodox Easter at midnight
The service and the light
In Romania, Greece, Bulgaria and Cyprus the Easter service begins close to midnight, and the faithful carry a candle lit from the priest’s flame. In 2026 Orthodox Easter falls on 12 April, so the service opens near 00:00 EEST, which is 22:00 BST on the evening before.
Watching from afar
Broadcasters carry the midnight service live. A viewer in London who wants to see the candles pass from hand to hand should tune in at 22:00 BST, not at midnight on the British clock.
Kyiv and the wider region
Meetings with Ukraine
Kyiv is on EET. A video call set for 10:00 in Kyiv takes place at 08:00 GMT. Officials and aid organisations often schedule briefings at 11:00 or 12:00 local time, which are 09:00 or 10:00 GMT. A “convert GMT to EET” calculation for each briefing avoids a late joining.
Moldova and Cyprus
Chișinău and Nicosia follow the same two-hour gap with Greenwich. Local broadcasts and government announcements are timed on EET in winter and EEST in summer.

Reading the table
Each entry pairs a Greenwich hour with the matching Eastern European hour and notes when the date moves. The rows follow the same addition of two hours that the calculator uses when you convert GMT to EET.
Ten readings with minutes
Examples
01:05 GMT corresponds to 03:05 EET. 03:20 GMT corresponds to 05:20 EET. 05:50 GMT corresponds to 07:50 EET. 07:35 GMT corresponds to 09:35 EET. 10:10 GMT corresponds to 12:10 EET. 13:25 GMT corresponds to 15:25 EET. 16:40 GMT corresponds to 18:40 EET. 19:55 GMT corresponds to 21:55 EET. 22:15 GMT corresponds to 00:15 EET (next day). 23:05 GMT corresponds to 01:05 EET (next day).
The minutes do not change
Because the difference is a whole number of hours, the minutes in the result match the input.
What part of the day is it?
The Eastern European rhythm
06:00 GMT corresponds to 08:00 EET (morning). 08:00 GMT corresponds to 10:00 EET (morning). 10:00 GMT corresponds to 12:00 EET (around midday). 12:00 GMT corresponds to 14:00 EET (afternoon). 14:00 GMT corresponds to 16:00 EET (afternoon). 16:00 GMT corresponds to 18:00 EET (evening). 18:00 GMT corresponds to 20:00 EET (evening). 20:00 GMT corresponds to 22:00 EET (night). 22:00 GMT corresponds to 00:00 EET (night).
Using the list
The words in brackets describe the part of the day on the EET clock. They help you avoid proposing a call in the middle of the night.
European zones seen from Greenwich
The ladder
Add zero for London and Lisbon in winter, one for Central Europe, two for Eastern Europe, three for Moscow and Istanbul, and five and a half for India. If someone says “Eastern European”, use two hours.
One moment on five clocks
When London reads 12:00, Paris reads 13:00, Athens 14:00, Moscow 15:00 and Mumbai 17:30. A list of this kind spares readers a separate convert GMT to EET.
Dated examples
January
On Friday 23 January, 14:00 GMT is 16:00 EET. Neither side is on summer time.
Early April
On Friday 3 April, 14:00 BST is 16:00 EEST. Both moved their clocks on 29 March.
August
On Friday 14 August, 14:00 BST is 16:00 EEST. The gap is unchanged.
November
On Friday 13 November, 14:00 GMT is 16:00 EET. Both returned to winter time on 25 October.
Checklist: how to convert GMT to EET
Before
Read the labels
EET is winter, EEST is summer. A British “GMT” written in July often means BST.
Decide the target
For the wall clock in Athens or Bucharest, add two hours all year relative to London. For zero-meridian UTC, add three in summer.
After
Add two
If the total reaches 24, subtract 24 and advance the date.
Check the date
GMT hours from 22:00 onward move to the next date.
Lapland in December
Santa Claus and the northern lights
Many British families fly to Finnish Lapland in December. The village at Rovaniemi opens its main attractions from about 09:00 to 17:00 local time, which is 07:00 to 15:00 GMT. Daylight lasts barely a few hours around midday, so the visits are planned around the brief light. A charter that leaves a British airport at 07:00 GMT lands about three and a half hours later at 10:30 GMT, which is 12:30 EET.
Aurora tours
Night excursions to watch the aurora start at about 21:00 EET and finish after midnight. In Greenwich time, that is 19:00 to around 22:00 GMT. Parents who want to convert GMT to EET for a children’s bedtime back home should remember that the late return is still early evening in Britain.
Cyprus holidays and the Paphos flight
Sun in the eastern Mediterranean
Cyprus is on EET, two hours ahead of Greenwich in winter. A flight that leaves London at 08:00 GMT and takes about four and a half hours lands at 12:30 GMT, which is 14:30 EET. The first afternoon on the island is therefore shorter than a traveller expects, and the hotel dinner is served at 19:00 EET, 17:00 GMT.
Coming home
A late evening flight from Paphos at 22:30 EET leaves at 20:30 GMT and lands at about 01:00 GMT the next day. Passengers should remember that the local clock reads 03:00 on the island at the moment they land in Britain.
Helsinki’s start-up week
Programme times
The big start-up conference in Helsinki each November runs from about 09:00 to 18:00 EET, which is 07:00 to 16:00 GMT. A founder in London who wants to catch the morning pitches must join by 07:00 GMT. A “convert GMT to EET” calculation done once for the whole schedule gives both a Finnish and a British timetable.
Evening events
Side events begin at about 19:00 EET, which is 17:00 GMT, so London colleagues can watch the opening drinks right after their own working day. The late parties at 22:00 EET are at 20:00 GMT.
Mistakes when you convert GMT to EET
Adding only one hour
One hour is for Central Europe. Eastern Europe is two.
Subtracting by habit
Athens is ahead of London. If the answer is smaller, you subtracted.
Forgetting the date
23:15 GMT is 01:15 EET the next day. Do not keep the original date.
Mixing up Egypt in April
Cairo changes its clock later than Europe. Check the calendar before a spring call.
Frequently asked questions
