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.

AWST is 15 hours ahead of MST (standard time).

Daylight Saving Time: MST observes DST; AWST does not. The offset between them shifts by 1 hour twice a year — in spring and autumn — when MST changes its clocks.

Most of Arizona stays on MST year-round (does not observe DST). The Navajo Nation within Arizona does observe DST.

AWST · Western Australia Time

Standard offset +08:00

Does not observe DST

Western Australia Time remains on a constant standard offset for the year.

Western Australia does not observe DST; state referendums have repeatedly rejected permanent daylight saving.
