When the difference changes
Pacific 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 – November 1, 2026Hawaii Standard Time is 3 hours behind
- November 1, 2026 – March 14, 2027Hawaii Standard Time is 2 hours behind
- March 14, 2027 – onwardsHawaii Standard Time is 3 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
Pacific Time
Clocks go back one hour at 2am local time, becoming PST.
Hawaii Standard Time
