Military time, also known as 24-hour time, is a system used to tell time based on a 24-hour clock. It is commonly used in military, healthcare, and aviation industries for clear and concise communication. The term military time is often interchangeably used with army time, 24-hour clock, and Universal Time Code (UTC). Other synonyms for military time include 24-hour system, military clock, and global time. While military time may seem confusing for those used to the standard 12-hour clock, its use allows for precision and accuracy in timekeeping, making it an essential tool in many professions.
