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.

AKST is 18 hours behind JST (standard time).

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