UTC → GMT Converter
UTC and GMT are effectively the same offset (0h), but different categories — UTC is the scientific standard, GMT is a civil zone. The conversion is trivial, but the conceptual distinction matters for precision applications like aviation, finance, and navigation.

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.
UTC and GMT share the same standard UTC offset.
Daylight Saving Time: GMT observes DST; UTC does not. The offset between them shifts by 1 hour twice a year — in spring and autumn — when GMT changes its clocks.
