What is ART in EET?

Eastern European Time is 6 hours ahead

Argentina Time is on UTC−3:00 and Eastern European Time is on UTC+3:00 right now. Eastern European Time is on daylight saving, so its clocks read EEST. The gap changes during the year — see below.

When the difference changes

Argentina Time and Eastern European Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

Now – October 24, 2026Eastern European Time is 6 hours ahead
October 24, 2026 – March 27, 2027Eastern European Time is 5 hours ahead
March 27, 2027 – onwardsEastern European Time is 6 hours ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

Argentina Time

No clock changes

Clocks go back one hour — 4:00 am becomes 3:00 am local time, and the zone is on EET after that.
