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.
HST is 10 hours behind UTC (standard time).
Daylight Saving Time: Neither UTC nor HST observes Daylight Saving Time. The 10-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.
UTC · Universal Time
Standard offset +00:00
Universal Time remains on a constant standard offset for the year.
UTC is the global reference time standard. By definition, it does not observe daylight saving.
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.
