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.
MST is 17 hours behind AEST (standard time).
Daylight Saving Time: MST observes DST; AEST does not. The offset between them shifts by 1 hour twice a year — in spring and autumn — when MST changes its clocks.

Eastern Australia Time remains on a constant standard offset for the year.
This record represents the year-round UTC+10 designation used in Queensland, which does not observe DST. NSW, Victoria, Tasmania, and ACT use AEST as the winter half of a cycle that transitions to AEDT (UTC+11) in summer — see the AEDT record for those DST dates and rules.
