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.

SGT is 18 hours ahead of HST (standard time).

Daylight Saving Time: Neither HST nor SGT observes Daylight Saving Time. The 18-hour offset is constant year-round with no seasonal variation.

HST · Hawaii Time

Standard offset −10:00

Does not observe DST

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.

SGT · Singapore Time

Standard offset +08:00

Does not observe DST

Singapore Time remains on a constant standard offset for the year.

Singapore does not observe DST.
