What is PST in AWST?
Australian Western Standard Time is 15 hours ahead
Pacific Time is on UTC−7:00 and Australian Western Standard Time is on UTC+8:00 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
Pacific Time and Australian Western Standard 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, 2026Australian Western Standard Time is 15 hours ahead
- November 1, 2026 – March 14, 2027Australian Western Standard Time is 16 hours ahead
- March 14, 2027 – onwardsAustralian Western Standard Time is 15 hours ahead
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.

Clocks go back one hour at 2am local time, becoming PST.

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