What is HST in PST?
Pacific Time is 3 hours ahead
Hawaii Standard Time is on UTC−10:00 and Pacific Time is on UTC−7:00 right now. Pacific Time is on daylight saving, so its clocks read PDT. The gap changes during the year — see below.

When the difference changes
Hawaii Standard Time and Pacific 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, 2026Pacific Time is 3 hours ahead
- November 1, 2026 – March 14, 2027Pacific Time is 2 hours ahead
- March 14, 2027 – onwardsPacific Time is 3 hours ahead
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
Hawaii Standard Time
Hawaii Standard Time stays on HST all year, so its offset from UTC never moves.
