When the difference changes

Australian Eastern Time and Brasília Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – October 4, 2026Brasília Time is 13 hours behind
  2. October 4, 2026 – April 4, 2027Brasília Time is 14 hours behind
  3. April 4, 2027 – October 3, 2027Brasília Time is 13 hours behind
  4. October 3, 2027 – onwardsBrasília Time is 14 hours behind

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

Australian Eastern Time

Sunday, October 4, 2026

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on AEDT after that.

Brasília Time

No clock changes

Brasília Time stays on BRT all year, so its offset from UTC never moves.

Scheduling between the two

There is no overlap between a nine-to-six working day in Sydney and one in São Paulo — the gap is too wide. A call has to sit early or late for one side. Early morning in Sydney is the usual compromise, since that is late afternoon or evening in São Paulo.

Australian Eastern Time (AEST) is used in Melbourne, Canberra and Brisbane. Queensland stays on AEST all year while the southern states move to AEDT.

Brasília Time (BRT) is used in Rio de Janeiro and Brasília. Brazil ended daylight saving in 2019.
