Does it account for Daylight Saving Time?

Yes, our converter uses the IANA timezone database, which includes all current DST rules for every timezone in the world.

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All timezones are defined as offsets from UTC.

Can I compare multiple timezones at once?

Yes, you can add multiple cities or timezones and see the equivalent times side by side.

How many timezones are there in the world?

There are 38 distinct UTC offsets in use, ranging from UTC-12 to UTC+14. This includes half-hour (UTC+5:30 India, UTC+9:30 Australia) and 45-minute offsets (UTC+5:45 Nepal, UTC+8:45 Australia).

What is the International Date Line?

The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. When you cross it westward, you gain a day; crossing eastward, you lose a day.

Why do some timezones have 30 or 45 minute offsets?

Countries chose offsets that best matched their solar noon. India uses UTC+5:30 and Nepal uses UTC+5:45 because standard hourly offsets didn't align well with their geography.

Which country has the most timezones?

France has the most (12 timezones) due to overseas territories. Russia spans 11 timezones. The US has 6 (including Hawaii and Alaska).

Key Facts about EET

•EET covers countries across three continents: Europe, Asia, and Africa.
•Cairo is the most populous city in the EET zone.
•Turkey used to be on EET but permanently moved to UTC+03:00 in 2016.
•Finland, the Baltic states, and Greece all use EET.

Daylight Saving:Yes – switches to EEST

Comparing Time Zones: EET and BST

EET runs on Eastern European Time (EET) at UTC+02:00. BST runs on British Summer Time (BST) at UTC+01:00. That puts EET 1 hour behind BST — a difference of -1h at the current offsets.

In practice, when it is 9:00 AM in EET it is 8:00 AM in BST. Midnight in EET is 11:00 PM in BST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert EET to BST time

Scheduling a call from EET to BST: a 10:00 AM start in EET lands at 9:00 AM in BST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both EET and BST are inside the 9-to-5 working day between 10:00 AM and 5:00 PM EET time (9:00 AM–4:00 PM BST). That is roughly 7 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in EET is 7:00 PM in BST makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM EET" is unambiguous; "3 PM" across a -1h gap is not.
Block 10:00 AM–5:00 PM EET as the recurring meeting window if you work primarily from EET and need BST colleagues present.

About EET (Eastern European Time)

Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya). During summer, most EET countries switch to Eastern European Summer Time (EEST, UTC+03:00). Turkey permanently moved to UTC+03:00 in 2016, effectively leaving EET.

About BST (British Summer Time)

British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.

Best time to call between EET and BST

Both EET and BST sit inside the 9 AM – 5 PM working day between 10:00 AM–5:00 PM EET, which is 9:00 AM–4:00 PM BST. That gives roughly 7 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

EET and BST share 7 hours of working-hours overlap (10:00 AM–5:00 PM EET), so scheduling a live meeting is straightforward.

EET is 1 hour behind BST (EET UTC+02:00 → BST UTC+01:00). The shared working window is 10:00 AM–5:00 PM EET. Remember to re-check around daylight-saving transitions.
