What is AWST in EST?
Eastern Time is 12 hours behind
Australian Western Standard Time is on UTC+8:00 and Eastern Time is on UTC−4:00 right now. Eastern Time is on daylight saving, so its clocks read EDT. The gap changes during the year — see below.

When the difference changes
Australian Western Standard Time and Eastern 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, 2026Eastern Time is 12 hours behind
- November 1, 2026 – March 14, 2027Eastern Time is 13 hours behind
- March 14, 2027 – onwardsEastern Time is 12 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.
Eastern Time
Clocks go back one hour at 2am local time, becoming EST.

Scheduling between the two
There is no overlap between a nine-to-six working day in Perth and one in New York — 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 New York.
Australian Western Standard Time (AWST) is used in Western Australia, which does not observe daylight saving
Eastern Time (EDT) is used in Toronto, Atlanta, Miami, Detroit and most of the US east coast
