Time-zone reference

Eastern European Time

EET is the standard-time label used by parts of eastern Europe and nearby regions during the non-summer part of the year.

Eastern European standard and summer time

EET denotes UTC+02:00. The Helsinki clock is a regional example and can instead show the summer-time offset. EET describes an offset family; it does not imply identical historical or future rules in every location that uses the label.

Use the city where your meeting happens when converting. Comparing Helsinki with Paris on a given date answers a regional question more precisely than assuming a relationship between two abbreviations year-round.

Conversion example

10:00 EET is 08:00 UTC. A 10:00 reading at UTC+03:00 is 07:00 UTC.

A common scheduling mistake

Do not copy one city’s seasonal transition dates to every country associated with EET.

The chart uses each abbreviation’s fixed standard offset. In summer many of these regions switch to daylight labels (EDT, PDT, BST, CEST, AEDT), so for a real meeting use the time zone converter with the meeting date.

Where EET is used

These cities on our world clock use EET during standard time and EEST during daylight saving time:

When EET and EEST switch in Helsinki

  • : EEST begins — at 03:00 local time clocks go forward to 04:00.
  • : EET resumes — at 04:00 local time clocks go back to 03:00.
  • : EEST begins — at 03:00 local time clocks go forward to 04:00.
  • : EET resumes — at 04:00 local time clocks go back to 03:00.

Dates for Europe/Helsinki from the IANA time zone database bundled with this build. Other regions using EET can switch on different dates.

EET questions

What is EET in UTC?

EET (Eastern European Time) is UTC+2, 2 hours ahead of UTC. To convert EET to UTC, subtract 2 hours: 12:00 EET is 10:00 UTC.

Is EET the same as EEST?

No. EET is the standard-time label and EEST is the daylight-saving label for the same region, one hour ahead. Most places that use EET in winter switch to EEST in summer, so a time written as EET during the summer months is usually a mislabel for EEST. When in doubt, name the city or use the IANA zone Europe/Helsinki.

Which cities use EET?

Cities on our world clock that use EET in standard time include Cairo, Athens, Kyiv.
