What is AWST in PST?
Pacific Time is 15 hours behind
Australian Western Standard Time is on UTC+8:00 and Pacific Time is on UTC−7:00 right now. Pacific Time is on daylight saving, so its clocks read PDT. The gap changes during the year — see below.

When the difference changes
Australian Western 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:
- Now – November 1, 2026Pacific Time is 15 hours behind
- November 1, 2026 – March 14, 2027Pacific Time is 16 hours behind
- March 14, 2027 – onwardsPacific Time is 15 hours behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
Australian Western Standard Time
Australian Western Standard Time stays on AWST all year, so its offset from UTC never moves.

Scheduling between the two
There is no overlap between a nine-to-six working day in Perth and one in Los Angeles — the gap is too wide. A call has to sit early or late for one side. Early morning in Perth is the usual compromise, since that is late afternoon or evening in Los Angeles.
Australian Western Standard Time (AWST) is used in Western Australia, which does not observe daylight saving
