What is EST in AEST?
Australian Eastern Time is 14 hours ahead
Eastern Time is on UTC−4:00 and Australian Eastern Time is on UTC+10:00 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
Eastern Time and Australian 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 – October 3, 2026Australian Eastern Time is 14 hours ahead
- October 3, 2026 – November 1, 2026Australian Eastern Time is 15 hours ahead
- November 1, 2026 – March 14, 2027Australian Eastern Time is 16 hours ahead
- March 14, 2027 – April 3, 2027Australian Eastern Time is 15 hours ahead
- April 3, 2027 – October 2, 2027Australian Eastern Time is 14 hours ahead
- October 2, 2027 – onwardsAustralian Eastern 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.

Scheduling between the two
There is no overlap between a nine-to-six working day in New York and one in Sydney — the gap is too wide. A call has to sit early or late for one side. Early morning in New York is the usual compromise, since that is late afternoon or evening in Sydney.
Eastern Time (EDT) is used in Toronto, Atlanta, Miami, Detroit and most of the US east coast
Australian Eastern Time (AEST) is used in Melbourne, Canberra and Brisbane. Queensland stays on AEST all year while the southern states move to AEDT.
