Australian Eastern Time Zone - AET

Australian Eastern Time or AET is a blanket term used to describe the local time observed in both the Australian Eastern Daylight Time (AEDT) and Australian Eastern Standard Time (AEST) zones. Because of that, Australian Eastern Time is not static and it switches depending on whether or not Daylight Saving is active.

Australian Eastern Daylight Time

Australian Eastern Daylight Time or AEDT has a UTC offset of +11:00. This means that the time zone is 11 hours ahead of Coordinated Universal Time. The time zone is primarily observed by territories and states in Australia and the Pacific Islands during the summer months when Daylight Saving is active. After Daylight Saving is over – during the winter – the affected territories switch to Australian Eastern Standard Time or AEST.

Australian Eastern Standard Time

Australian Eastern Standard Time or AEST has a UTC offset of +10:00. This means that the time zone is 10 hours ahead of Coordinated Universal Time. The time zone is primarily observed by territories and states in Australia during the winter months when Daylight Saving is inactive. As soon as Daylight Saving begins – during the summer – the affected territories switch to Australian Eastern Daylight Time or AEDT.
