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 5 hours ahead of GST (standard time).
Daylight Saving Time: Neither GST nor JST observes Daylight Saving Time. The 5-hour offset is constant year-round with no seasonal variation.
