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.
AEST is 20 hours ahead of HST (standard time).
Daylight Saving Time: Neither HST nor AEST observes Daylight Saving Time. The 20-hour offset is constant year-round with no seasonal variation.

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.
AEST · Eastern Australia Time
Standard offset +10:00
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.
