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:

  1. Now – March 14, 2027Pacific Time is 2 hours ahead
  2. March 14, 2027 – November 6, 2027Pacific Time is 3 hours ahead
  3. November 6, 2027 – onwardsPacific Time is 2 hours ahead

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

No clock changes

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on PDT after that.

Scheduling between the two

Working hours overlap from 9:00 am to 4:00 pm HST, which is 11:00 am to 6:00 pm PST. Anything inside that window falls in the normal working day at both ends.

Hawaii Standard Time (HST) is used in all of Hawaii, which does not observe daylight saving

Pacific Time (PST) is used in San Francisco, Seattle, Las Vegas and Vancouver
