What Is a Time Zone?

A time zone is a region of the world that observes a uniform standard time for legal, commercial, and social purposes. Time zones are usually centered around the Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC) standard.

How Time Zone Conversion Works

Each time zone has a UTC offset (e.g., UTC−5, UTC+2). When converting:

  • The selected date and time are interpreted in the source time zone.
  • The system converts them to UTC time.
  • Then it applies the destination time zone offset.
  • Daylight Saving Time (DST) shifts are automatically accounted for.

Why Time Zones Differ

  • Longitude differences
  • Government decisions and daylight saving rules
  • Local cultural and regional considerations

Common Use Cases

  • Scheduling international meetings
  • Travel itinerary planning
  • Stock market and trading sessions
  • Streaming or gaming with global players
