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.
Does anything I type leave my device?
No. The arithmetic runs in your browser; nothing is uploaded and there is no server to upload it to. Load the page once and it keeps working with the network switched off.
Iasi dormitories, Pune stand-ups and the Estonian choir: one offset
Medical students in Iasi call home after the evening seminar. A Bucharest team joins a stand-up with a client in Pune. Estonia broadcasts its choir festival after sunset. Whoever follows these events from Mumbai, Pune or Delhi has to convert EET to IST, and in the dark half of the year the sum is short: add three and a half hours. 10:00 EET reads 13:30 on an Indian wall, 15:00 EET reads 18:30, and 21:00 EET tips over midnight to 00:30 the next day. Because India never touches its clocks, the only thing that shifts the result is Eastern Europe itself: from 29 March to 24 October, on EEST, the gap is two and a half hours.
Below you find the rule, ready-made tables, a portrait of each zone and a series of real situations, from lecture halls to departure boards. Everything is computed locally on your device.
Indian students in Romania
Calls home
A student in Iași who phones home at 18:00 EET calls at 21:30 IST, India’s dinner hour. A call at 22:00 EET arrives at 01:30 IST, when the family is asleep.
Exams
An exam scheduled for 09:00 EET takes place at 12:30 IST. Parents in India wait for the results at midday, not in the morning. A “convert EET to IST” calculation made beforehand shows why the news reaches them in the afternoon.
Bucharest developers for Pune clients
The shared window
A Bucharest office open from 09:00 to 17:00 works, on Indian time, from 12:30 to 20:30. Clients in Pune can talk to the team between 12:30 and 17:00 IST, four and a half hours a day.
The weekly meeting
A meeting fixed for 14:00 EET is at 17:30 IST, right at the end of the Indian day. A “convert EET to IST” calculation shows why many choose 11:00 EET, which is 14:30 IST.
The Song Festival in Estonia
The main concert
The great choir concert begins at 19:00 EEST, which is 21:30 IST. Estonians in India watch live, after dinner.
The finale
The finale at 22:00 EEST is at 00:30 IST the following night. Whoever wants to see it live stays up.
The Athens Classic Marathon
The start at Marathon
The November race starts at 09:00 EET, which is 12:30 IST. Indian runners in Greece follow it live at midday.
The finish in the stadium
The winners enter the Panathenaic Stadium around 11:15 EET, which is 14:45 IST. A “convert EET to IST” calculation shows at once that the finish falls in the Indian afternoon.
Romania’s National Day
The military parade
The 1 December parade begins around 10:00 EET, which is 13:30 IST. Romanians in India, and Indians who admire the parade, watch live at lunchtime.
The evening concert
The concert at 20:00 EET is at 23:30 IST. A “convert EET to IST” calculation shows that the Romanian evening ends, in India, toward midnight.
Finland’s Independence Day
The presidential reception
The 6 December reception, broadcast at 18:00 EET, is at 21:30 IST. Finns in Bangalore watch live after dinner.
Candles in the windows
The lighting of candles, at 18:00 EET, takes place at 21:30 IST. A “convert EET to IST” calculation shows at once that for India it falls toward the end of the evening.
Flights between Bucharest and Delhi
The flight with a stop
A flight with one stop in Istanbul that leaves Bucharest at 06:00 EET and takes nearly eleven hours lands at 20:30 IST the same day. The ticket shows 06:00 and 20:30, as for a journey of fourteen and a half hours.
The direct flight from Helsinki
A flight from Helsinki to Delhi that leaves at 17:00 EET and takes nearly eight hours lands at 04:30 IST the next day. The ticket shows 17:00 and 04:30, as for a flight of eleven and a half hours.
How to convert EET to IST, in three stages
Stage one: the addition
The Indian clock runs three and a half hours ahead of the East European one. The time in Romania, on a 24-hour clock, is increased by 3:30; the minutes move along with the hours.
Stage two: the date
A total of 24:00 or more means the next day: subtract 24. 21:00 EET gives 24:30, so 00:30 IST tomorrow; 23:45 EET gives 27:15, so 03:15 IST tomorrow.
Stage three: the check
00:30 EET is 04:00 IST. 04:15 EET is 07:45 IST. 08:00 EET is 11:30 IST. 11:45 EET is 15:15 IST. 16:00 EET is 19:30 IST. 19:15 EET is 22:45 IST. In summer, 16:00 EEST is 18:30 IST.
Eastern Europe on the clock
Who keeps EET
Romania, Bulgaria, Greece, Cyprus, Finland, Estonia, Latvia, Lithuania, Ukraine and Moldova run on EET (UTC+2) in winter. In summer these countries move to UTC+3, under the name EEST, between the last Sundays of March and October.
Egypt
Egypt sits on EET but has its own summer calendar. Its summer runs from the last Friday of April to the last Thursday of October, so against India the gap is three and a half hours until 23 April, two and a half from 24 April to 29 October, and three and a half again afterwards.
The Indian clock, in short
No seasons
The whole subcontinent, from Gujarat in the west to Assam in the east, shares UTC+5:30 and has never adopted daylight saving. The half hour is why results end in :30 or :00 rather than keeping the same minutes: 09:15 EET becomes 12:45 IST.
Neighbours
Sri Lanka follows the same time. Nepal is a quarter of an hour ahead of India, Pakistan half an hour behind and Bangladesh half an hour ahead.
Two working days on one dial
Where the days meet
When a Romanian team opens its laptops at 09:00, Pune is already at 12:30; when the Romanians log off at 17:00, Pune reads 20:30. Seen from Bucharest, an Indian 09:00-17:00 shift occupies 05:30-13:30. The only hours both sides are at work run from 12:30 to 17:00 IST, so a call placed in that stretch rarely catches anyone off duty.
Who gets the awkward slot
A 10:00 EET call lands at 13:30 IST, just after lunch in India. A 17:00 EET call lands at 20:30 IST, when Indian colleagues are already thinking of the commute home.
One hop to the Gulf
A flight from Bucharest to Dubai leaves at 05:00 EET and takes nearly five hours: it touches down at 10:00 EET, which is 12:00 on Dubai clocks and 13:30 IST. A traveller who carries on to India therefore moves the watch another hour and a half.
One Romanian hour, four dates
Winter
Thursday 22 January, 16:00 EET: 19:30 IST, a three-and-a-half-hour gap.
Around the March switch
Thursday 26 March still gives 19:30 IST for 16:00 EET. By Thursday 2 April the same 16:00 is EEST and reads 18:30 IST, because the East European clocks advanced on 29 March while India stayed put.
Mid-summer
Thursday 6 August, 16:00 EEST: 18:30 IST, a gap of two and a half hours.
Back to winter
After 25 October the gap widens again. Thursday 29 October and Thursday 3 December both put 16:00 EET at 19:30 IST.
The few months with an hour less
The interval
Between the last Sunday of March and the last Sunday of October the East European clock is advanced and the Indian one is not. The distance between EET and IST then falls to two and a half hours.
What to do
A “convert EET to IST” calculation made with the winter figure gives, in this interval, a result an hour too high. Subtract an hour and the result is right.
Diwali in Bucharest
The evening of lights
The Indian community in Bucharest celebrates Diwali in the evening, at 18:00 EET, which is 21:30 IST. Relatives in India follow the prayer live.
The midnight fireworks
Fireworks at 22:00 EET are at 01:30 IST the following night. A “convert EET to IST” calculation shows at once that they fall after the Indian midnight.
Technical support from Romania for Indian customers
The afternoon shift
A support centre in Romania serving customers in India works from 08:00 EET, which is 11:30 IST. The first calls come at the Indian lunchtime.
Closing time
The centre closes at 17:00 EET, which is 20:30 IST. A “convert EET to IST” calculation made beforehand shows that a call placed after that hour is no longer taken.
Indian films shot in Romania
The film sets
Indian film crews working in Romania start the day at 07:00 EET, which is 10:30 IST. Producers in Mumbai follow the shoot in the first part of their day.
The day’s report
The day’s report, sent at 19:00 EET, reaches Mumbai at 22:30 IST. A “convert EET to IST” calculation made beforehand shows that producers receive it late in the evening.
Doctors in Cluj, patients in Hyderabad
Booking a video visit
A 09:00 EET slot is 12:30 IST, so Indian patients see a Romanian specialist over their lunch break rather than first thing.
Writing the date on a prescription
A note stamped 02:00 IST on 5 March was written at 22:30 EET on 4 March. When the date matters, a “convert EET to IST” calculation that also shows the day avoids a prescription dated a day out.
Reading a Romanian weather bulletin from India
When a warning ends
A frost alert valid until 18:00 EET lapses at 21:30 IST. Relatives watching from India add three and a half hours to each time printed in the bulletin.
Which version is current
Bulletins are stamped with Romanian local time. Running that stamp through a “convert EET to IST” calculation tells you at once how long ago the latest update appeared.
The weeks and months that need care
Period by period
The difference between EET and IST depends on the date. In 2026: 1 January to 28 March and 25 October to 31 December: IST stands 3 hours 30 minutes ahead of EET; 29 March to 24 October: IST stands 2 hours 30 minutes ahead of EET.
What to do about it
During the summer periods the zones are called EEST and IST. The calculator assumes the winter gap of 3 hours 30 minutes; adjust by the difference shown for your date. Whenever you convert EET to IST, check which period the date falls in first.
A 24-hour lookup table
From EET to IST
00:00 EET corresponds to 03:30 IST. 01:00 EET corresponds to 04:30 IST. 02:00 EET corresponds to 05:30 IST. 03:00 EET corresponds to 06:30 IST. 04:00 EET corresponds to 07:30 IST. 05:00 EET corresponds to 08:30 IST. 06:00 EET corresponds to 09:30 IST. 07:00 EET corresponds to 10:30 IST. 08:00 EET corresponds to 11:30 IST. 09:00 EET corresponds to 12:30 IST. 10:00 EET corresponds to 13:30 IST. 11:00 EET corresponds to 14:30 IST. 12:00 EET corresponds to 15:30 IST. 13:00 EET corresponds to 16:30 IST. 14:00 EET corresponds to 17:30 IST. 15:00 EET corresponds to 18:30 IST. 16:00 EET corresponds to 19:30 IST. 17:00 EET corresponds to 20:30 IST. 18:00 EET corresponds to 21:30 IST. 19:00 EET corresponds to 22:30 IST. 20:00 EET corresponds to 23:30 IST. 21:00 EET corresponds to 00:30 IST (next day). 22:00 EET corresponds to 01:30 IST (next day). 23:00 EET corresponds to 02:30 IST (next day).
What the table shows
On the left of each pair is a EET reading; on the right, the IST reading for the same moment, with the date change marked. The sums are the ones the calculator performs when you convert EET to IST. Unlike most pairs, the minutes change here by thirty: :00 turns into :30, :30 turns into :00 and the hour moves with it. These rows use the standard (winter) gap; on the dates listed in the period section the gap is different.

00:30 EET corresponds to 04:00 IST. 01:30 EET corresponds to 05:00 IST. 02:30 EET corresponds to 06:00 IST. 03:30 EET corresponds to 07:00 IST. 04:30 EET corresponds to 08:00 IST. 05:30 EET corresponds to 09:00 IST. 06:30 EET corresponds to 10:00 IST. 07:30 EET corresponds to 11:00 IST. 08:30 EET corresponds to 12:00 IST. 09:30 EET corresponds to 13:00 IST. 10:30 EET corresponds to 14:00 IST. 11:30 EET corresponds to 15:00 IST. 12:30 EET corresponds to 16:00 IST. 13:30 EET corresponds to 17:00 IST. 14:30 EET corresponds to 18:00 IST. 15:30 EET corresponds to 19:00 IST. 16:30 EET corresponds to 20:00 IST. 17:30 EET corresponds to 21:00 IST. 18:30 EET corresponds to 22:00 IST. 19:30 EET corresponds to 23:00 IST. 20:30 EET corresponds to 00:00 IST (next day). 21:30 EET corresponds to 01:00 IST (next day). 22:30 EET corresponds to 02:00 IST (next day). 23:30 EET corresponds to 03:00 IST (next day).
Why it helps
Many meetings, broadcasts and scheduled jobs start at half past the hour. This table gives the IST time for each of them at a glance, which saves you a second calculation. Read these rows as standard-time values and check the period section for dates where the difference changes.

Awkward minutes from EET to IST
01:05 EET corresponds to 04:35 IST. 03:20 EET corresponds to 06:50 IST. 05:50 EET corresponds to 09:20 IST. 07:35 EET corresponds to 11:05 IST. 10:10 EET corresponds to 13:40 IST. 13:25 EET corresponds to 16:55 IST. 16:40 EET corresponds to 20:10 IST. 19:55 EET corresponds to 23:25 IST. 22:15 EET corresponds to 01:45 IST (next day). 23:05 EET corresponds to 02:35 IST (next day).
Checking your work
Compare your own answer with the pattern in these rows. Unlike most pairs, the minutes change here by thirty: :00 turns into :30, :30 turns into :00 and the hour moves with it. These rows use the standard (winter) gap; on the dates listed in the period section the gap is different.
Daily rhythm at the other end
IST time of day for chosen EET hours
06:00 EET corresponds to 09:30 IST (morning). 08:00 EET corresponds to 11:30 IST (morning). 10:00 EET corresponds to 13:30 IST (around midday). 12:00 EET corresponds to 15:30 IST (afternoon). 14:00 EET corresponds to 17:30 IST (afternoon). 16:00 EET corresponds to 19:30 IST (evening). 18:00 EET corresponds to 21:30 IST (evening). 20:00 EET corresponds to 23:30 IST (night). 22:00 EET corresponds to 01:30 IST (night).
Using the brackets
The brackets show whether the IST hour falls at night, in the early morning, during the working day or in the evening, which helps when you must convert EET to IST for a call. Winter-time arithmetic applies to these rows; for the dates in the period section, correct the result accordingly.
A quick routine to convert EET to IST
First
Confirm the zones
EET is also used by Egypt, which has its own summer calendar. IST can also mean Irish Standard Time or Israel Standard Time; here it means India.
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 EET becomes 12:45 IST.
After the sum
The operation
Add 3 hours 30 minutes. If the result passes midnight, correct the date: readings from 20:30 fall on the next date.
A second example
Try a later hour: 22:40 EET is 02:10 IST (next day).
Traps to avoid when you convert EET to IST
Subtracting instead of adding
IST is in front of EET: expect a bigger number, not a smaller one.
Losing the date
A EET time from 20:30 moves to the next date. Keeping the original date produces a one-day error.
The standard figure in the wrong weeks
On some dates in 2026 the distance between EET and IST differs from the usual one, so read the period list before you apply it.
Confusing the abbreviation
Cairo, Athens, Bucharest and Helsinki share the EET offset, though Egypt follows its own summer calendar. Indian Standard Time is UTC+5:30; the same three letters are used for Israel and for Ireland’s summer clock, which this page does not cover.
Questions and answers
What is the difference between EET and IST?
3 hours 30 minutes, and IST is ahead of EET. That is the standard figure; on some dates in 2026 it differs, as the period list shows.
What do I do to convert EET to IST?
Add 3 hours 30 minutes to the EET time, then fix the date if the result passes midnight.
How much is 21:45 EET in IST?
01:15 IST on the next day in the standard period.
Is the gap the same in every month?
No, it differs on some dates; the period list above shows which.
Is the time I enter sent anywhere?
No. Everything happens on your own device.
