Frequently Asked Questions

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. It is effectively the same as GMT (Greenwich Mean Time) with no daylight saving adjustments. All time zones are expressed as UTC+ or UTC− offsets. For example, New York is UTC−5 (EST) or UTC−4 (EDT during daylight saving).

Daylight Saving Time is the practice of advancing clocks by 1 hour during warmer months so evening daylight lasts longer. Not all countries observe DST — notably China, Japan, and India do not. This converter uses your browser's Intl API which automatically accounts for DST transitions.

Because of DST. For example, "America/New_York" is UTC−5 in winter (Eastern Standard Time) but UTC−4 in summer (Eastern Daylight Time). The IANA timezone database (used by all browsers) contains the full history of every region's DST rules, so conversions are always accurate.
