Australian Eastern Time (AET) or the Australian Eastern Time Zone. This can add a bit of confusion as the term Australian Eastern Time does not differentiate between standard time and Daylight Saving Time, so Australian Eastern Time switches between AEST and AEDT in areas that use DST during part of the year.

Australia has two generic time zones that include both standard and daylight time: Australian Eastern Time (AET) and Australian Central Time (ACT). The country has a complex set of time zones, some of which have an unusual UTC offset.

Converting AEDT to Other Australian Time Zones

  • Australian Eastern Daylight Time (AEDT) is 30 minutes ahead of Australian Central Daylight Time (ACDT).
    To convert AEDT to ACDT, subtract half an hour.
  • Australian Eastern Daylight Time (AEDT) is 2 hours and 15 minutes ahead of Australian Central Western Standard Time (ACWST).
    To convert AEDT to ACWST, subtract two hours and 15 minutes.
  • Australian Eastern Daylight Time (AEDT) is 3 hours ahead of Australian Western Standard Time (AWST).
    To convert AEST to AWST, subtract three hours.
