Time difference between Amsterdam and Honolulu

Honolulu is 12 hours behind Amsterdam

Amsterdam, the Netherlands is UTC+1 · Honolulu, the United States is UTC−10 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Amsterdam goes forward on the last Sunday in March and back on the last Sunday in October and Honolulu does not change its clocks.
