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.

A Black Sea festival, seen from Houston
A summer festival on the Romanian coast opens its main stage at 22:00. The Bucharest marathon sets off on Sunday morning at 9:00. The midsummer bonfires in Finland are lit on the night of the solstice, at 23:00. Anyone living in Chicago, Houston or Dallas who wants to know what the clock says at home at those moments will convert EET to CST. In winter time the calculation is a subtraction: eight hours. 22:00 EET becomes 14:00 CST, 9:00 EET becomes 01:00 CST, and 23:00 EET becomes 15:00 CST. Any Eastern European time before 08:00 belongs to the previous day in central America. Eight hours holds in summer too; the distance falls to seven only in two short stretches, 8 to 28 March and 25 to 31 October.
Next come events from eastern Europe followed in the Midwest, then the rule, the tables and the two zones. The calculation runs in the browser; no figure reaches a server.
Neversea and the Romanian coast
The main stage
The big concerts on the beach at Constanța begin around 22:00 EEST, which is 2:00 p.m. CDT. American spectators watch live in the middle of the afternoon.
The afternoon programme
Bands scheduled for 17:00 EEST play at 9:00 a.m. CDT. A “convert EET to CST” calculation made beforehand shows that in the Midwest they fall at the start of the working day.
The Bucharest marathon
The Sunday start
The race starts in the morning, at 9:00 EEST in October, which is 1:00 a.m. CDT. Americans who want to see the elite pack stay up at night or watch the recording.
The finish
The winners arrive after almost two hours, around 11:10 EEST, which is 3:10 a.m. CDT. For the Midwest it is still the dead of night.
Midsummer in Finland
The fires of the bright night
The midsummer and solstice bonfires are lit around 23:00 EEST, which is 3:00 p.m. CDT. Finns in Chicago watch live in the afternoon.
The festive evening
Concerts on the lakeshores begin at 20:00 EEST, which is 12:00 CDT. A “convert EET to CST” calculation tells you at once that they fall, in central America, at midday.
The Athens Classic Marathon
In the footsteps of Pheidippides
The November race starts from Marathon at 9:00 EET, which is 1:00 a.m. CST. American runners in Texas usually watch the summary.
The finish in the Panathenaic Stadium
The winners enter the stadium around 11:15 EET, which is 3:15 a.m. CST. A “convert EET to CST” calculation made beforehand shows why the live broadcast is seen only at night.
The film festival in Transylvania
Evening screenings
A gala screening at 20:00 EEST is at 12:00 p.m. CDT. Film fans in Chicago watch on their lunch break.
The awards
The awards gala at 21:30 EEST is at 1:30 p.m. CDT. For the Midwest it is an afternoon broadcast.
Wine Day in Moldova
The opening of the celebration
The celebration in the first part of October begins at 12:00 EEST, which is 4:00 a.m. CDT. Moldovans in Chicago watch live in the early morning or in a repeat.
The evening concert
The concert at 19:00 EEST is at 11:00 a.m. CDT. A “convert EET to CST” calculation tells you at once whether you can see it during a mid-morning break.
The rose festival in Bulgaria
The June parade
The parade at Kazanlak sets off at 14:00 EEST, which is 6:00 a.m. CDT. Californians and Texans catch it with their first coffee.
Picking the flowers
The ceremonial picking starts at 06:00 EEST, which is 10:00 p.m. CDT on the previous evening. Whoever does a “convert EET to CST” calculation with the date in view does not mix up the day.
How to convert EET to CST: three questions
How much do you subtract?
Eight hours. EET is UTC+2 and CST is UTC−6, so the American Central clock stands eight hours behind Bucharest, Athens and Helsinki. The East European time is written on a 24-hour clock, and 8 is taken from it.
When do you go back a day?
When the result is negative: then add 24. That happens for every time before 08:00: 03:00 EET is 19:00 CST yesterday, 07:30 EET is 23:30 CST yesterday.
Which values are worth remembering?
08:00 EET is 00:00 CST. 10:45 EET is 02:45 CST. 14:00 EET is 06:00 CST. 19:00 EET is 11:00 CST. 22:00 EET is 14:00 CST. 23:45 EET is 15:45 CST. On summer time, 22:00 EEST is 14:00 CDT, the same figure.
The clock in the heart of America
Where to find it
From Winnipeg to Houston and from Chicago to Mexico City, the winter clock reads UTC−6. With spring the American states move to UTC−5, under the name CDT, while Mexico keeps its clock.
Why it matters
A Romanian poster announces the local hour at home. People living in the Midwest therefore often convert EET to CST before planning to watch.
Eastern Europe’s clock, briefly
Its countries
Romania, Bulgaria, Greece, Cyprus, Finland, Estonia, Latvia, Lithuania, Ukraine and Moldova keep their winter clock on EET (UTC+2). In summer the clock advances an hour, between the last Sundays of March and October.
Egypt
Egypt also stays on EET but decides its own summer dates. Against American Central time it is seven hours away, instead of eight, between 8 March and 23 April and on the last two days of October.
Eight hours from dial to dial
Working days
While a Romanian institution works (09:00 to 17:00), it is night and early morning in Texas (01:00 to 09:00). When the working day begins in Dallas, it is nearing its end in Romania: 09:00 CST is 17:00 EET. The two schedules therefore never overlap.
Who rings first
From Romania, the best time to call west is the end of the day: 16:00 EET gives 8:00 a.m. CST. A call at 12:00 EET would ring at 4:00 a.m. CST.
Over the ocean
A flight with one stop from Bucharest to Chicago that leaves at 11:00 EET and takes nearly thirteen hours lands at 16:00 CST on the same day. The ticket says 11:00 and 16:00, as for a trip of five hours, although the flight is much longer.
The Bucharest exchange and the Chicago markets
The Romanian session
The Bucharest exchange trades roughly between 10:00 and 18:00 EET, which is 2:00 to 10:00 a.m. CST. Investors in Chicago rarely follow it live.
The grain exchange opens
The Chicago grain exchange opens at 8:30 a.m. CST, which is 16:30 EET, after the Romanian one has closed. A “convert EET to CST” calculation shows that the two markets never work together.
Dated examples
January
On Saturday 24 January, 19:00 EET is 11:00 CST. Both continents are on standard time.
March
On Saturday 14 March, 19:00 EET is 12:00 CDT. America moved to summer time on 8 March and eastern Europe only on the 29th, so the real gap is seven hours.
July
On Saturday 25 July, 19:00 EEST is 11:00 CDT. Both are on summer time, and the gap is eight hours.
October and December
On Saturday 31 October, 19:00 EET is 12:00 CDT, because Europe returned to standard time on 25 October and America only the next day. On Saturday 12 December, 19:00 EET is 11:00 CST.
When the distance is seven hours
The three weeks of March
From 8 March, when America advances its clocks, until 28 March, when eastern Europe does the same, the clocks stand seven hours apart.
The week in October
From 25 October, when eastern Europe sets its clocks back, until 1 November, when America does the same, the distance is again seven hours. Anyone who then does a “convert EET to CST” calculation on the usual eight-hour figure arrives an hour too early.
Colleagues in Bucharest, colleagues in Dallas
The common hour
Teams in the two cities meet at 17:00 EET, which is 9:00 a.m. CST. For the Romanians it is the end of the day, for the Texans the beginning.
What stays in writing
Work that ends at 17:30 EET reaches Dallas at 9:30 a.m. CST, just as the American colleagues walk into the office. Written notes keep the thread.
More clocks, counted from Bucharest
How many hours to subtract
From Romanian time subtract one hour for Berlin, two for London, seven for New York, eight for Chicago, nine for Denver and ten for Los Angeles. Add two and a half hours for Delhi.
One instant, four cities
When it is 19:00 in Bucharest, it is 17:00 in London, 12:00 in New York, 11:00 in Chicago and 9:00 in Los Angeles. An invitation that lists them all spares the reader any convert EET to CST.
Romanian students at Texan universities
Online classes
A lesson at 18:00 EET is at 10:00 a.m. CST. Students in Texas follow it in mid-morning.
Submission deadlines
A deadline of 23:59 EET falls at 3:59 p.m. CST the same day. Whoever counts the deadline by home midnight loses whole hours.
Family calls and birthdays
The right hour
A family call made at 20:00 EET reaches 12:00 p.m. CST, an American’s lunch break. One at 14:00 EET reaches 6:00 a.m. CST, when many are barely awake.
The festive evening
The Christmas Eve meal at 19:00 EET is at 11:00 a.m. CST. A “convert EET to CST” calculation shows that Americans in the centre can follow it on a screen in mid-morning.
The weeks and months that need care
Period by period
The difference between EET and CST depends on the date. In 2026: 1 January to 7 March, 29 March to 24 October and 1 November to 31 December: CST stands 8 hours behind EET; 8 to 28 March and 25 to 31 October: CST stands 7 hours behind EET.
How to apply it
In the summer periods the labels are EEST and CDT. The calculator above uses the winter gap of 8 hours. For other dates, adjust the result by the difference between that figure and the gap listed for the period. Whenever you convert EET to CST, check which period the date falls in first.
All twenty-four hours side by side
EET against CST
00:00 EET = 16:00 CST (previous day). 01:00 EET = 17:00 CST (previous day). 02:00 EET = 18:00 CST (previous day). 03:00 EET = 19:00 CST (previous day). 04:00 EET = 20:00 CST (previous day). 05:00 EET = 21:00 CST (previous day). 06:00 EET = 22:00 CST (previous day). 07:00 EET = 23:00 CST (previous day). 08:00 EET = 00:00 CST. 09:00 EET = 01:00 CST. 10:00 EET = 02:00 CST. 11:00 EET = 03:00 CST. 12:00 EET = 04:00 CST. 13:00 EET = 05:00 CST. 14:00 EET = 06:00 CST. 15:00 EET = 07:00 CST. 16:00 EET = 08:00 CST. 17:00 EET = 09:00 CST. 18:00 EET = 10:00 CST. 19:00 EET = 11:00 CST. 20:00 EET = 12:00 CST. 21:00 EET = 13:00 CST. 22:00 EET = 14:00 CST. 23:00 EET = 15:00 CST.
Notes on the table
The table lists the full day. Where the CST date differs from the EET date, the entry says so. Use it as a reference whenever you convert EET to CST. With a whole-hour offset the minutes are untouched; if they differ in your result, the input was misread. These rows use the standard (winter) gap; on the dates listed in the period section the gap is different.
The :30 rows
EET to CST, thirty minutes past
00:30 EET = 16:30 CST (previous day). 01:30 EET = 17:30 CST (previous day). 02:30 EET = 18:30 CST (previous day). 03:30 EET = 19:30 CST (previous day). 04:30 EET = 20:30 CST (previous day). 05:30 EET = 21:30 CST (previous day). 06:30 EET = 22:30 CST (previous day). 07:30 EET = 23:30 CST (previous day). 08:30 EET = 00:30 CST. 09:30 EET = 01:30 CST. 10:30 EET = 02:30 CST. 11:30 EET = 03:30 CST. 12:30 EET = 04:30 CST. 13:30 EET = 05:30 CST. 14:30 EET = 06:30 CST. 15:30 EET = 07:30 CST. 16:30 EET = 08:30 CST. 17:30 EET = 09:30 CST. 18:30 EET = 10:30 CST. 19:30 EET = 11:30 CST. 20:30 EET = 12:30 CST. 21:30 EET = 13:30 CST. 22:30 EET = 14:30 CST. 23:30 EET = 15:30 CST.
Purpose of the list
These are the readings people forget to check: events at :30. Look up the EET time and read the CST time beside it instead of repeating the calculation. Winter-time arithmetic applies to these rows; for the dates in the period section, correct the result accordingly.
Ten readings with minutes
Examples from EET to CST
01:05 EET = 17:05 CST (previous day). 03:20 EET = 19:20 CST (previous day). 05:50 EET = 21:50 CST (previous day). 07:35 EET = 23:35 CST (previous day). 10:10 EET = 02:10 CST. 13:25 EET = 05:25 CST. 16:40 EET = 08:40 CST. 19:55 EET = 11:55 CST. 22:15 EET = 14:15 CST. 23:05 EET = 15:05 CST.
What to notice
These are less round examples, with minutes. Because the difference is a whole number of hours, the minutes in the answer are the same as in the question. Read these rows as standard-time values and check the period section for dates where the difference changes.
What part of the day is it?
CST equivalents for each EET hour
06:00 EET = 22:00 CST (night). 08:00 EET = 00:00 CST (night). 10:00 EET = 02:00 CST (night). 12:00 EET = 04:00 CST (night). 14:00 EET = 06:00 CST (early morning). 16:00 EET = 08:00 CST (morning). 18:00 EET = 10:00 CST (morning). 20:00 EET = 12:00 CST (around midday). 22:00 EET = 14:00 CST (afternoon).
How to use the list
The words in brackets describe the part of the day in CST. They help you avoid planning a call or a task for the middle of the night after you convert EET to CST. The gap used here is the standard winter one; the period section lists the dates on which it differs.
Before you convert EET to CST: a short checklist
First
Read the labels
EET is also used by Egypt, which has its own summer calendar. The abbreviation CST is shared with China (UTC+8) and Cuba (UTC−5); on this page it always means Central North America.
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 EET becomes 01:15 CST.
After the sum
The operation
Subtract 8 hours. If the result passes midnight, correct the date: readings before 08:00 fall on the previous date.
A second example
An evening check: 22:40 EET gives 14:40 CST.
Mistakes when you convert EET to CST
Adding instead of subtracting
CST is behind EET, so the answer should be smaller than the starting hour. A larger number means an addition slipped in.
Losing the date
A EET time before 08:00 moves to the previous date. If the date stays put, the answer is a full day out.
The standard figure in the wrong weeks
On some dates in 2026 the distance between EET and CST differs from the usual one, so read the period list before you apply it.
Confusing the abbreviation
A Romanian schedule in July says EEST (UTC+3), not EET. Three countries share the letters CST; only the North American one, UTC−6, is used on this page.
Questions and answers
How far apart are EET and CST?
8 hours, and CST is behind EET. That is the standard figure; on some dates in 2026 it differs, as the period list shows.
How do I convert EET to CST?
Subtract 8 hours from the EET time, then fix the date if the result passes midnight.
How much is 09:00 EET in CST?
01:00 CST in the standard period.
Do the seasons affect this conversion?
Yes, on some dates; the period list above shows which.
Does the page keep what I type?
No. The calculation runs in your browser.
