How Does Military Time Work, And What Countries Use It? Source

In addition to its use in certain industries, some countries throughout the world use a 24-hour time format rather than the 12-hour format that we see as standard in the U.S. This means that most people in the country follow the same time zone, making coordinating schedules and planning events easier. Many nations worldwide, as well as professionals in occupations where accuracy is paramount, use military time. Citizens of most countries apart from United States, Australia, the United Kingdom, and the Phillippines use military time in their day-to-day lives. Regardless of the location, however, military time is the common method of time notation among people working in the armed forces, emergency services, science, astronomy, and meteorology. Workers in the aforementioned professions use 24-hour timekeeping because it helps keep their communications brief and concise and leaves no room for misinterpretation. Nowadays, military time is used all over the world. Military time is a method of measuring the time based on the full 24 hours of the day rather than two groups of 12 hours indicated by AM and PM. Using military time (http://www.e-miraeoa.co.kr/) is the standard method used to indicate time for medication administration. The use of military time reduces potential confusion that may be caused by using AM and PM and also avoids potential duplication when giving scheduled medications. For example, instead of stating medication is due at 7 AM and 7 PM, it is documented on the medication administration record (MAR) as due at 0700 and 1900. See Figure 5.5[1] for an example clock and Table 5.3 for a military time conversion chart. Distinguishing the two diurnal repetitions of this sequence.
