What is a Timezone?

A timezone is a region of the Earth that observes a uniform standard time for legal, commercial, and social purposes. Timezones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.

Key Concepts:

  • UTC (Coordinated Universal Time): The primary time standard by which the world regulates clocks and time
  • IANA Timezone Database: The standard database of timezone information used worldwide
  • Daylight Saving Time (DST): Seasonal time changes observed in many regions
  • GMT vs UTC: GMT (Greenwich Mean Time) is often used interchangeably with UTC, though technically UTC is the modern standard
