The Difference Between Standard and Military Time Conversion

While both convey time of day, there are key differences between standard AM/PM time and the military 24-hour format:

12-Hour AM/PM Clock vs. 24-Hour Format
AM/PM clock is divided into two 12 hour cycles (AM and PM)
Military time uses a single 24 hour cycle from 0000 to 2359
AM/PM adds ambiguity about morning or afternoon
Leading zeroes (e.g. 07:00 vs. 7:00) used in military time
Colons separate hours and minutes on 12-hour clock
When to Use Military Time vs. Standard Time
Military time used internationally, in aviation, medicine and by military
Standard 12 hour clock AM/PM regular time used in everyday life in many English-speaking nations
Military time avoids AM/PM confusion so preferable when precise coordination required across time zones

The History and Origins of Military Time 24 Hour Clock

The 24-hour time format traces back thousands of years to early civilizations.

Early Development in the Egyptian and Roman Empires

  • Egyptians divided day into 24 units around 2000 BC
  • Romans further divided day into AM and PM with midnight as MDI (media noctis inclinatio or 'middle of the night inclination')

Modern Military Time Adoption and Usage

  • Formal 24 hour standard time adopted in late 19th century
  • Used by military organizations to synchronize across locations
  • Now widely used internationally in timetables, aviation, computing etc.

Did You Know: The 24-hour time format is used on the International Space Station. Since the space station orbits the Earth about every 90 minutes, it passes through all time zones with each orbit. Using military time avoids confusion that could be caused by the constant time zone changes. This allows astronauts and ground control to precisely coordinate schedules and operations.

The Benefits of Using Military Time

There are clear advantages to using military time notation in appropriate situations:

Eliminates Ambiguity of AM/PM Notation

  • Removes confusion around when events occur in the AM or PM
  • Particularly useful when coordinating across time zones

Enhanced Precision and Consistency

  • Leading zeroes and 4-digit formatting (0700 vs. 7:00) reduce errors
  • Omitted colons avoid inconsistencies in written materials

In summary, converting and speaking military time like 1745 hours is straightforward once you know the simple rules. With origins dating back millennia and crucial roles in modern coordination, the 24-hour format has stood the test of time.
