What is Australian Central Daylight Time (ACDT)?
Australian Central Daylight Time (ACDT) is the daylight saving time observed in parts of central Australia, specifically South Australia and the town of Broken Hill in New South Wales. During the summer months, these regions move their clocks forward by one hour, resulting in an offset of UTC+10:30.
Our interactive clock is built to automatically adjust between the standard time (ACST - UTC+9:30) and daylight saving time (ACDT - UTC+10:30) based on the current date, ensuring you never have to manually check the season. Note that the Northern Territory (e.g., Darwin) does not participate in daylight saving time and remains on ACST year-round.
ACDT/ACST Time Difference
Understanding the unique half-hour offsets of Central Australia is key to avoiding errors:
- ACDT is 10.5 hours ahead of UTC, while ACST is 9.5 hours ahead.
- It is always 30 minutes behind the Australian Eastern Time (AEDT/AEST) zones like Sydney and Melbourne.
- During summer (ACDT), it is 5.5 hours ahead of Indian Standard Time (IST). During winter (ACST), it is 4.5 hours ahead of IST.
