CategoriesUnits & Measurements

ACDT stands for Australian Central Daylight Time, a time zone abbreviation.

South Australia and Broken Hill switch to this UTC+10:30 daylight time from the first Sunday in October to the first Sunday in April.

Example: The Adelaide Fringe opening night begins at 7:30 p.m. ACDT.

Usage notes

Because Western Australia, the Northern Territory and Queensland do not switch, mainland Australia runs five different clock times in summer: UTC+8, +9:30, +10, +10:30 and +11. That patchwork complicates national TV schedules, which are often delayed by state.
