What AWST and EST Actually Are

AWST — Australian Western Standard Time

Perth. Standing at UTC+8:00 as written, and the region does not change its clocks, so that offset holds all year. Western Australia does not observe daylight saving, so Perth stays on UTC+8 all year.

Western Australia has held four referendums on daylight saving and rejected it every time, most recently in 2009.

EST — Eastern Standard Time

New York, Toronto, Washington DC, Atlanta, Miami, Boston. Standing at UTC-5:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to EST. Australia also uses EST for its own Eastern Standard Time (UTC+10), now more often written AEST.

Eastern Standard Time is only actually in force from early November to mid-March. For the other eight months the same region is on EDT, which is why so many EST conversions are quietly wrong.

What This Means in Practice

The date changes mid-working-day

For 3 of the eight hours in a normal AWST working day, the equivalent EST time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.

This gap is not fixed

EST changes its clocks and AWST does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.

Nearly opposite sides of the clock

At 12 hours apart, one side's morning is the other side's night. Handing work over at the end of a shift usually beats trying to get both parties in the same call.
