Understanding Time Zones

Time zones are regions of the globe that observe a uniform standard time for legal, commercial, and social purposes. They generally follow the boundaries of countries or their subdivisions.

Key Concepts:

  • UTC (Coordinated Universal Time): The primary time standard by which the world regulates clocks. Formerly known as GMT (Greenwich Mean Time).
  • Offset: The difference in hours and minutes from UTC. For example, London is UTC+0 (or UTC+1 during British Summer Time).
  • DST (Daylight Saving Time): The practice of advancing clocks during warmer months so that darkness falls at a later clock time. Not all regions observe DST.

Common Time Zone Abbreviations:

  • GMT: Greenwich Mean Time (UTC+0)
  • BST: British Summer Time (UTC+1)
  • EST/EDT: Eastern Standard/Daylight Time (UTC-5/-4)
  • PST/PDT: Pacific Standard/Daylight Time (UTC-8/-7)
  • CET/CEST: Central European Time/Summer Time (UTC+1/+2)
  • JST: Japan Standard Time (UTC+9)
  • AEST/AEDT: Australian Eastern Standard/Daylight Time (UTC+10/+11)
