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 18 hours ahead of HST (standard time).
Daylight Saving Time: Neither HST nor AWST observes Daylight Saving Time. The 18-hour offset is constant year-round with no seasonal variation.

DST schedule for 2026
Current-year daylight saving start and end dates for the selected zones.
HST · Hawaii Time
Standard offset −10:00
Hawaii Time remains on a constant standard offset for the year.
Hawaii does not observe DST. The Aleutian Islands portion of HAST does observe DST (becoming HADT, UTC−9), but population there is negligible. For practical purposes HST is a fixed-offset zone.
AWST · Western Australia Time
Standard offset +08:00
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.
