What is EET in JST?

Japan Standard Time is 6 hours ahead

Eastern European Time is on UTC+3:00 and Japan Standard Time is on UTC+9:00 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

Eastern European Time and Japan Standard 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 25, 2026Japan Standard Time is 6 hours ahead
October 25, 2026 – March 28, 2027Japan Standard Time is 7 hours ahead
March 28, 2027 – onwardsJapan Standard 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

Eastern European Time

Sunday, October 25, 2026

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

Japan Standard Time

No clock changes

Japan Standard Time stays on JST all year, so its offset from UTC never moves.
