This PST to HST converter turns any time in Pacific Standard Time (PST) into Hawaii Standard Time (HST), using your device clock so daylight saving is applied automatically. HST is 2 hours behind PST when both zones are on standard time, and 3 hours behind during the summer months when clocks have shifted. PST is UTC−8 (PDT: UTC−7); HST is UTC−10.
PST covers Los Angeles, San Francisco, Seattle; HST covers Honolulu, Hilo. 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 PST and HST?
HST is 2 hours behind PST on standard time. During daylight saving the gap changes to 3 hours. That comes from the UTC offsets: PST is UTC−8 and HST is UTC−10. For example, 9 am PST = 7 am HST, and in summer 9 am PST = 6 am HST.
Is HST ahead of or behind PST?
HST is 2 hours behind PST, so when it is noon in PST it is 10 am in HST. Ahead means the clock there already shows a later time; a call at 5 pm PST lands at 3 pm HST.
Does PST or HST observe daylight saving time in 2026?
PST switches to PDT (UTC−7) on March 8 and back on November 1 in 2026. HST keeps UTC−10 all year. 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 PST and HST?
Standard office hours (9 am to 5 pm) overlap from 11 am to 5 pm PST, which is 9 am to 3 pm HST. 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 PST and HST?
PST (Pacific Standard Time) is used in Los Angeles, San Francisco, Seattle, Vancouver. HST (Hawaii Standard Time) is used in Honolulu, Hilo. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
