11pm EST is 1:00 pm AEST the next day
11pm EDT is 1:00 pm AEST in Australian Eastern Time, on the next day. AEST is 14 hours ahead of EST today, and that gap changes during the year, so this is recomputed rather than assumed.
What time is 11pm EST in AEST?
It is 1:00 pm. Australian Eastern is 14 hours ahead of Eastern, so you add 14 hours to 11:00 pm and the result lands on the next day. 11pm is late evening in Eastern, the wind-down before midnight, while 1:00 pm is afternoon in Australian Eastern, the second half of the working day.
ISO 8601 would write this instant as 2026-09-26 03:00Z, the same moment expressed with no zone opinion at all. Both 11pm EST and 1:00 pm AEST are local readings of that one instant, which is the only thing either clock is really describing.
11pm EST to AEST in the hours either side
The four hours before and after 11pm, in case the meeting moves. Note that the calendar date does not stay put across this window: it changes partway through, which is exactly where scheduling mistakes come from.

Is 11pm EST a good time to call AEST?
It works for them, not obviously for you. 1:00 pm is a normal working hour in Australian Eastern, but 11pm is late evening in Eastern, the wind-down before midnight. Expect to be the one making the compromise.
Does daylight saving change 11pm EST to AEST?
Yes. Sampled at 11pm on every day of 2026, the gap takes 3 different values. Today it is 14 hours, which is why the answer above is dated rather than fixed.
Eastern Time is currently on EDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-4 to UTC-5.
Australian Eastern Time is currently on AEST and changes next on Sunday, October 4, 2026, when the clock jumps forward from 1:59 am to 3:00 am and the offset moves from UTC+10 to UTC+11.
11pm AEST to EST, the other way round
Running the question the other way is a different conversion, not a mirror image, because the two zones can be in different daylight saving states on the same date. 11pm AEST is 9:00 am EST, which is a different reading from the answer above, because the two directions are separate questions. One wrinkle worth knowing: EST and EDT are two names for the same zone, not two zones. Eastern Time reads EST in winter and EDT in summer. When somebody types "est to aest" they nearly always mean the zone rather than the literal winter offset, so this page resolves EST to America/New_York and AEST to Australia/Sydney and applies whichever offset is genuinely in force on the day.
