Standard Time vs Military Time(AM/PM)?

Military time and regular time are two different ways of expressing the same thing – the passage of hours. Military time is similar to the 24-hour clock, which counts from 0000 (or “zero hundred”) to 2359 (or “twenty-three fifty-nine”). Regular time is the 12-hour clock, which counts from 12am to 11:59pm. The biggest difference between military and regular time is that regular time uses two periods of twelve hours for one day whereas military time uses a period of twenty four hours for one day. This means that in military time, 1:00am regular time would be expressed as 0100. Alternatively, 1:00pm would be expressed as 1300 military time. Military time can be helpful when talking about an event or activity that will take place at a specific hour, since it eliminates any confusion between morning and afternoon time values. This is why military time is preferred for emergency services, military, and any other industry which demands accuracy from its communication of time.
