Who Invented Military Time?
Military time, also known as the 24-hour clock, has been a standard format for timekeeping in the military for centuries. But who is credited with its invention?

The Early Days of Timekeeping
Before we dive into the history of military time, let’s take a brief look at the evolution of timekeeping. The earliest recorded timekeeping systems date back to ancient civilizations such as the Egyptians, Babylonians, and Mayans. These societies used sundials, water clocks, and astronomical observations to divide the day into equal parts.
The Introduction of the 12-Hour Clock
The 12-hour clock, which is still widely used today, is believed to have originated in ancient Rome. The Roman Empire used a system of 12 equal periods, with the day beginning at sunrise and ending at sunset. This system was based on the division of the day into 12 equal parts, with the hours marked by the sun’s position in the sky.
The Advent of the 24-Hour Clock
The 24-hour clock, on the other hand, is believed to have originated in the 17th century in Europe. The first recorded use of the 24-hour clock was in 1656 by the German astronomer Johannes Hevelius. Hevelius used a 24-hour clock in his book "Prodromus Astronomiae" to describe the timing of astronomical events.
Early Adoption of the 24-Hour Clock
The 24-hour clock was initially used by astronomers and mathematicians to simplify complex calculations and to avoid the ambiguity of the 12-hour clock. However, it wasn’t until the late 18th century that the 24-hour clock began to gain widespread acceptance.
The French Revolution and the Adoption of Military Time
The French Revolution played a significant role in the adoption of the 24-hour clock. In 1793, the French National Convention adopted the 24-hour clock as the official timekeeping system for the country. This was partly due to the influence of mathematician and astronomer Pierre-Simon Laplace, who advocated for the use of the 24-hour clock in his book "A Philosophical Essay on Probabilities".
Why the 24-Hour Clock was Adopted
The 24-hour clock was adopted for several reasons:
- Clarity and Precision: The 24-hour clock eliminates the ambiguity of the 12-hour clock, making it easier to communicate times accurately.
- International Compatibility: The 24-hour clock is a universal standard, making it easier for people from different countries and cultures to communicate and coordinate.
- Efficiency: The 24-hour clock simplifies scheduling and planning, as it eliminates the need to convert times between the 12-hour and 24-hour formats.
The Spread of Military Time
The 24-hour clock spread rapidly throughout the world, particularly in the military and scientific communities. The British Royal Navy adopted the 24-hour clock in the early 19th century, and by the mid-19th century, it had become the standard timekeeping system for the British military.
Military Time Around the World
Today, military time is used in most countries around the world, although the exact format may vary. Here is a breakdown of how military time is used in different countries:
| Country | Military Time Format |
|---|---|
| United States | 24-hour clock (e.g. 14:30) |
| United Kingdom | 24-hour clock (e.g. 1430) |
| Canada | 24-hour clock (e.g. 1430) |
| Australia | 24-hour clock (e.g. 1430) |
| Germany | 24-hour clock (e.g. 14:30) |
| France | 24-hour clock (e.g. 14h30) |
Conclusion
In conclusion, the invention of military time is a complex and multifaceted topic. While it is difficult to attribute the invention of the 24-hour clock to a single person, it is clear that the French Revolution played a significant role in its widespread adoption. Today, military time is used by militaries and governments around the world, and it continues to be an essential tool for communication and coordination.
