HST to PST — Hawaii to Pacific Time

Pacific Time is 2 hours ahead of Hawaii in winter and 3 hours ahead in summer.

The conversion rule

In winter, add 2 hours to Hawaii Time to get Pacific Time: 12:00 PM HST is 2:00 PM PST. Hawaii has no daylight saving, so once California springs forward to PDT the addition is 3 hours — noon HST is 3:00 PM in Los Angeles.

This is the friendliest mainland pairing for the islands: 9:00 AM–3:00 PM HST / 11:00 AM–5:00 PM PT in winter, 9:00 AM–2:00 PM HST / 12:00–5:00 PM PT in summer.

Frequently asked questions

How far ahead is California from Hawaii?

2 hours in winter, 3 in summer. PST is UTC−8 against Hawaii's fixed UTC−10; when California switches to PDT (UTC−7) the gap grows an hour.

What is 5:00 PM HST in Los Angeles?

7:00 PM PST in winter and 8:00 PM PDT in summer — Hawaii's close of business is California's evening.

Do flights between Honolulu and the West Coast cross a date line?

No — the International Date Line lies far west of Hawaii. Honolulu and Los Angeles share the same calendar date, just 2 or 3 clock hours apart.
