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.
EST is 5 hours behind GMT (standard time).
Daylight Saving Time: Both GMT and EST observe DST, but switch on different dates. For a few weeks each spring and autumn, the gap shifts by 1 hour — a common source of missed meetings and calendar tool errors.
