HST to CET — Central European Time is 11 hours ahead

Central European Time (CET) is 11 hours ahead of Hawaii Time (HST) while both are on standard time. Once daylight saving starts the gap becomes 12 hours ahead, so any recurring meeting between these two regions moves by an hour twice a year.

Standard time

11 hours ahead

Applies while neither zone is on daylight saving — broadly November to March in the northern hemisphere.

Daylight saving

12 hours ahead

Applies while the clocks are forward. This pair does not keep a constant gap, so check the date.

How the two zones line up

Hawaii Time sits at UTC−10 in winter and does not observe daylight saving. Central European Time sits at UTC+1 and UTC+2 respectively. The difference between those two offsets is the number you add or subtract.

Daylight saving

Standard working days do not overlap at all. One side will need to take the call early or late, so alternate who makes the sacrifice.
