How Time Zone Conversion Works
Time zone conversion works by comparing the UTC offset of one location to another. Every city or region is measured relative to Coordinated Universal Time (UTC), which acts as the global reference point for civil time.
ACST is 1 hour 30 minutes behind AEDT (standard time).
Daylight Saving Time: AEDT observes DST; ACST does not. The offset between them shifts by 1 hour twice a year — in spring and autumn — when AEDT changes its clocks.

AEDT is the daylight-saving designation used in southeastern Australia; Queensland remains on AEST (UTC+10) year-round and is not represented by this code. Two Australian territories have unusual DST offsets: Lord Howe Island (NSW) uses UTC+10:30 in winter and UTC+11 in summer — the only jurisdiction in the world with a 30-minute DST shift; Norfolk Island uses UTC+11 in winter and UTC+12 in summer, following the same transition dates as eastern states.

South Australia observes DST (ACDT, UTC+10:30); the Northern Territory remains on ACST year-round. SA has used the same Sunday transition dates as the eastern states since the 2008/09 DST season — older sources stating SA changes one week later are out of date.
