What is EET in HST?
Hawaii Standard Time is 13 hours behind
Eastern European Time is on UTC+3:00 and Hawaii Standard Time is on UTC−10:00 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 Hawaii 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, 2026Hawaii Standard Time is 13 hours behind
- October 25, 2026 – March 28, 2027Hawaii Standard Time is 12 hours behind
- March 28, 2027 – onwardsHawaii Standard Time is 13 hours behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
Eastern European Time
Clocks go back one hour at 2am local time, becoming EET.
Hawaii Standard Time
Hawaii Standard Time stays on HST all year, so its offset from UTC never moves.

Scheduling between the two
There is no overlap between a nine-to-six working day in Athens and one in Honolulu — the gap is too wide. A call has to sit early or late for one side. Early morning in Athens is the usual compromise, since that is late afternoon or evening in Honolulu.
Eastern European Time (EEST) is used in Helsinki, Bucharest, Kyiv and Cairo
Hawaii Standard Time (HST) is used in all of Hawaii, which does not observe daylight saving
