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.

JST is 18 hours ahead of AKST (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.

Hyder, Alaska (population ~50, southeastern panhandle) de facto follows Pacific Time to align with neighboring Stewart, British Columbia — it is technically in AKST territory but observes PST/PDT in practice. This is an extreme edge case and does not affect zone coverage.

JST · Japan Time

Standard offset +09:00

Does not observe DST

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

Japan has not observed daylight saving time since 1951.
