What is CST in AEST?

Australian Eastern Time is 17 hours ahead

Central Time is on UTC−6:00 and Australian Eastern Time is on UTC+11:00 right now. Australian Eastern Time is on daylight saving, so its clocks read AEDT. The gap changes during the year — see below.

When the difference changes

Central Time and Australian Eastern 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 – March 14, 2027Australian Eastern Time is 17 hours ahead
  2. March 14, 2027 – April 3, 2027Australian Eastern Time is 16 hours ahead
  3. April 3, 2027 – October 2, 2027Australian Eastern Time is 15 hours ahead
  4. October 2, 2027 – November 7, 2027Australian Eastern Time is 16 hours ahead
  5. November 7, 2027 – onwardsAustralian Eastern Time is 17 hours ahead

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.

Scheduling between the two

Working hours overlap from 4:00 pm to 6:00 pm CST, which is 9:00 am to 11:00 am AEDT. Anything inside that window falls in the normal working day at both ends.

A note on CST: it can also mean China Standard Time (UTC+8) and Cuba Standard Time (UTC−5). This page means US Central Time.

Central Time (CST) is used in Dallas, Houston, Mexico City and Winnipeg

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