What Is Australian Eastern Daylight Time?
Australian Eastern Daylight Time (AEDT) is the easternmost time zone in Australia. It is used in four Australian states and territories: Australian Capital Territory, New South Wales, Tasmania, and Victoria.
Australian Eastern Daylight Time shares a border with Australian Central Daylight Time (ACDT) in the west.
AEDT or AEST?
Australian Eastern Daylight Time (AEDT) is in use from the first Sunday in October to the first Sunday in April during Daylight Saving Time (DST). Australian Eastern Standard Time (AEST) is used during the remainder of the year.
AEDT Is the Australian Eastern Time Zone
In everyday usage, AEDT is often referred to as 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.
