EST to AEST — Australian Eastern Time is 16 hours ahead

Australian Eastern Time (AEST) is 16 hours ahead of Eastern Time (EST) while both are on standard time. Once daylight saving starts the gap becomes 14 hours ahead, so any recurring meeting between these two regions moves by an hour twice a year.

Standard time

16 hours ahead

Applies while neither zone is on daylight saving — broadly November to March in the northern hemisphere.

Daylight saving

14 hours ahead

Applies while the clocks are forward. This pair does not keep a constant gap, so check the date.

How the two zones line up

Eastern Time sits at UTC−5 in winter and UTC−4 in summer. Australian Eastern Time sits at UTC+11 and UTC+10 respectively. The difference between those two offsets is the number you add or subtract.

Daylight saving

Standard working days do not overlap at all. One side will need to take the call early or late, so alternate who makes the sacrifice.
