11pm AEST is 9:00 am EST
11pm AEST is 9:00 am EDT in Eastern Time. EST is 14 hours behind AEST today, and that gap changes during the year, so this is recomputed rather than assumed.
What time is 11pm AEST in EST?
It is 9:00 am. Eastern is 14 hours behind Australian Eastern, so you subtract 14 hours from 11:00 pm and the date does not change. 11pm is late evening in Australian Eastern, the wind-down before midnight, while 9:00 am is mid morning in Eastern, the busiest stretch of the working morning.
ISO 8601 would write this instant as 2026-09-26 13:00Z, the same moment expressed with no zone opinion at all. Both 11pm AEST and 9:00 am EST are local readings of that one instant, which is the only thing either clock is really describing.
11pm AEST to EST 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 AEST a good time to call EST?
It works for them, not obviously for you. 9:00 am is a normal working hour in Eastern, but 11pm is late evening in Australian Eastern, the wind-down before midnight. Expect to be the one making the compromise.
Does daylight saving change 11pm AEST to EST?
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.
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.
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.
11pm EST to AEST, 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 EST is 1:00 pm AEST, the next day, which is a different reading from the answer above, because the two directions are separate questions. One wrinkle worth knowing: AEST and AEDT are two names for the same zone, not two zones. Australian Eastern Time reads AEST in winter and AEDT in summer. When somebody types "aest to est" they nearly always mean the zone rather than the literal winter offset, so this page resolves AEST to Australia/Sydney and EST to America/New_York and applies whichever offset is genuinely in force on the day.
