Why use Military Time Instead of 12:38 PM?
Military time exists to eliminate miscommunication when telling the time. It helps to clearly differentiate between 12:38 pm and 12:38 am. For example if a departure time is stated as 12:38 it’s not immediately clear whether that means 12:38 pm or 12:38 am.
