Eastern Time (EST) is 15 hours behind Australian Eastern Time (AEST).

Here is every hour of the day in EST and the same moment in AEST.

The green rows are the hours when both zones are inside 9 AM to 5 PM. The row marked Now is the hour it is in Eastern Time right now.

A team split between ET and Sydney is never at work together between 9 AM and 5 PM.

Taking 9 AM to 5 PM on each clock as the working day, the two zones are never at work at the same moment, so a meeting means an early start or a late finish on one side.

A team spread across two time zones has fewer chances to notice someone drifting away. TeamPredict reads public LinkedIn signals to flag resignation risk early, wherever people work.

The gap between EST and AEST moves between 14 hours and 16 hours during the year.

The United States and eastern Australia change their clocks on different dates, in opposite halves of the year, so the gap changes more than once.

These are the clock changes of both zones in 2026 and 2027.

EST stands for Eastern Time and AEST for Australian Eastern Time on this page.

Eastern Time is EST (UTC−5) in winter and EDT (UTC−4) in summer. People write EST all year, and this page does too; the clock reads EDT right now. It moves its clocks forward at 2:00 AM on the second Sunday in March and back at 2:00 AM on the first Sunday in November.

Sydney, Melbourne and Canberra are on AEST (UTC+10) in winter and AEDT (UTC+11) in summer, and this page follows Sydney. The clock reads AEDT right now. They move forward on the first Sunday in October and back on the first Sunday in April, and Queensland stays on AEST all year.
