What AEDT means
AEDT stands for Australian Eastern Daylight Time, UTC+11. It is used in New South Wales, Victoria, Tasmania and the Australian Capital Territory.
It is a summer time: the daylight saving form of AEST (UTC+10), one hour ahead. In Sydney it applies from October to April: from the first Sunday of October at 2:00 AM to the first Sunday of April at 3:00 AM.
Australia’s time zones in practice
Australia’s states choose their own clock rules. Queensland, the Northern Territory and Western Australia stay on standard time all year, while New South Wales, Victoria, Tasmania, the ACT and South Australia move forward in October and back in April. In summer this gives the east coast two different times: Sydney on AEDT (UTC+11) and Brisbane on AEST (UTC+10).
The Northern Territory, South Australia and Broken Hill use a half-hour offset, ACST (UTC+9:30); South Australia and Broken Hill move to ACDT (UTC+10:30) in summer, while Darwin does not. Lord Howe Island moves by only 30 minutes. Because the southern summer spans New Year, the year’s first clock change in Australia is the move back in April.

AEDT converted to other zones
Every column is a fixed offset, so this table is valid on any date. Remember that the regions behind some columns switch to summer time (EST to EDT, CET to CEST, GMT to BST); the clock in those cities is then an hour later than the column.
