Why use military time in civilian jobs?

I've noticed that some civilian jobs use military time for scheduling and operations. Why do they prefer this system, and is it common in certain industries over others?

The usage of military time, also referred to as the 24-hour clock, is indeed prevalent in certain civilian sectors. The main reason behind this is to eliminate any potential confusion that can arise from the 12-hour clock, especially when it comes to distinguishing between AM and PM times.

Take emergency services, healthcare, and aviation as examples. In these sectors, clarity in communication is of utmost importance due to the critical nature and time sensitivity of their operations. The 24-hour clock system ensures that everyone is on the same page when it comes to interpreting a certain time of the day, leaving no room for misinterpretation or errors.

Moreover, international businesses and organizations also tend to use the 24-hour clock, as it's the standard format in most countries worldwide. This eliminates confusion during interactions with international partners or clients.

In summary, industries where activity span the entire 24-hour day and where precise communication and interpretation of time are critical are more likely to use the 24-hour clock or military time. However, its usage is less common in businesses that primarily operate during standard hours or where the exact time isn't a significant factor.
