4pm AEST is 6:00 am UTC
4pm AEST is 6:00 am UTC in Coordinated Universal Time. UTC is 10 hours behind AEST today, and that gap changes during the year, so this is recomputed rather than assumed.
What time is 4pm AEST in UTC?
It is 6:00 am. UTC is 10 hours behind Australian Eastern, so you subtract 10 hours from 4:00 pm and the date does not change. 4pm is afternoon in Australian Eastern, the second half of the working day, while 6:00 am is early morning in UTC, alarms, commutes and the first coffee.
The 12 hour clock reuses every number twice, so 4pm and 4am differ only by the meridiem. Converting 4pm AEST gives 6:00 am UTC; converting 4am AEST gives 6:00 pm UTC. Losing the am or pm loses half the answer.
4pm AEST to UTC in the hours either side
The four hours before and after 4pm, in case the meeting moves. The whole window stays on the same day in UTC, so only the hour changes.

Is 4pm AEST a good time to call UTC?
No. 6:00 am in UTC is early morning, alarms, commutes and the first coffee. Nobody is taking that call. The zones are 10 hours apart, so the nearest sensible slot is a different hour entirely.
Does daylight saving change 4pm AEST to UTC?
Yes. Sampled at 4pm on every day of 2026, the gap takes 2 different values. Today it is 10 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.
Coordinated Universal Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
4pm UTC 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. 4pm UTC is 2:00 am 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 utc" they nearly always mean the zone rather than the literal winter offset, so this page resolves AEST to Australia/Sydney and UTC to Etc/UTC and applies whichever offset is genuinely in force on the day.
