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 0 hours 30 minutes ahead of JST (standard time).

Daylight Saving Time: ACST observes DST; JST 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dates as the eastern states since the 2008/09 DST season — older sources stating SA changes one week later are out of date.
