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.
EST is 14 hours 30 minutes behind ACST (standard time).
Daylight Saving Time: ACST observes DST; EST does not. The offset between them shifts by 1 hour twice a year — in spring and autumn — when ACST changes its clocks.

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dates as the eastern states since the 2008/09 DST season — older sources stating SA changes one week later are out of date.
