This HST to PST converter turns any time in Hawaii Standard Time (HST) into Pacific Standard Time (PST), using your device clock so daylight saving is applied automatically. PST is 2 hours ahead of HST when both zones are on standard time, and 3 hours ahead during the summer months when clocks have shifted. HST is UTC−10; PST is UTC−8 (PDT: UTC−7).
HST covers Honolulu, Hilo; PST covers Los Angeles, San Francisco, Seattle. Because only PST observes daylight saving time, the difference is not constant through the year. The tables below show both cases, and the converter at the top always uses the rule in force on the date you pick.

Frequently asked questions
What is the time difference between HST and PST?
PST is 2 hours ahead of HST on standard time. During daylight saving the gap changes to 3 hours. That comes from the UTC offsets: HST is UTC−10 and PST is UTC−8. For example, 9 am HST = 11 am PST, and in summer 9 am HST = 12 pm PST.
Is PST ahead of or behind HST?
PST is 2 hours ahead of HST, so when it is noon in HST it is 2 pm in PST. Ahead means the clock there already shows a later time; a call at 5 pm HST lands at 7 pm PST.
Does HST or PST observe daylight saving time in 2026?
HST keeps UTC−10 all year. PST switches to PDT (UTC−7) on March 8 and back on November 1. Between those dates the difference in the table above shifts by an hour, which is the usual cause of missed calls in spring and autumn.
What is the best time for a meeting between HST and PST?
Standard office hours (9 am to 5 pm) overlap from 9 am to 3 pm HST, which is 11 am to 5 pm PST. Pick a slot inside that window and both sides stay within a normal working day. Check the daylight saving dates above, because the window moves by an hour when only one side has changed clocks.
Which cities use HST and PST?
HST (Hawaii Standard Time) is used in Honolulu, Hilo. PST (Pacific Standard Time) is used in Los Angeles, San Francisco, Seattle, Vancouver. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
