When the U.S. is on Standard Time, Hawaii (UTC-10) is 2 hours behind California (UTC-8/UTC-7).

When the U.S. is on Daylight Saving Time, Hawaii is 3 hours behind California.

In the U.S., Daylight Saving Time begins on the 2nd Sunday of March and ends on the 1st Sunday of November.

So when it's 2 AM HAST in Hawaii, the time in California is either 4 AM PST (during Standard Time) or 5 AM PDT (during Daylight Saving Time).

California is 2 hours ahead of Hawaii.
