24-hour Clock by the International Time Bureau

The 24-hour clock, also known as military time, is a timekeeping convention where the day is divided into 24 hours, running from midnight to midnight. It was popularized in the early 20th century by the International Time Bureau, and its adoption was driven by a need for standardized and unambiguous timekeeping in various fields, such as transportation, military, and scientific purposes.

  • Date: The International Time Bureau was established in 1912, and the 24-hour clock system gained popularity during World War I (1914-1918) and afterward.
  • Background: Before adopting the 24-hour clock, the 12-hour clock system was widely used. However, it led to confusion and ambiguity, especially in international communication, military operations, and railway timetables.
  • The International Time Bureau was an organization responsible for coordinating global timekeeping and promoting the adoption of universal time standards, including the 24-hour clock.
  • Key players: The International Time Bureau worked with international organizations, governments, and scientific communities to promote the adoption of the 24-hour clock.
  • Adoption: The 24-hour clock system was adopted by various countries and organizations, including the military, railroads, and airlines, to avoid confusion and improve communication.
  • Trivial fact: The 24-hour clock does not use “a.m.” and “p.m.” Instead, the hours are numbered from 00 to 23, and the minutes and seconds are from 00 to 59.
  • Effects on pop culture: The 24-hour clock has been portrayed in movies and television series, especially in military and espionage-related genres, where precise time communication is essential.
  • Widespread use: The 24-hour clock is commonly used worldwide in various contexts, including digital devices, aviation, public transportation, and scientific research.
