When the difference changes
Central 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 – March 28, 2027Hawaii Standard Time is 11 hours behind
- March 28, 2027 – October 31, 2027Hawaii Standard Time is 12 hours behind
- October 31, 2027 – onwardsHawaii Standard Time is 11 hours behind
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
Central European Time
Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on CEST after that.
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 Paris and one in Honolulu — the gap is too wide. A call has to sit early or late for one side. Early morning in Paris is the usual compromise, since that is late afternoon or evening in Honolulu.
Central European Time (CET) is used in Berlin, Madrid, Rome, Amsterdam, Warsaw and Stockholm
