Which time does 0400hrs indicate in civilian terms?

The time indicated by 0400 hours in military or 24-hour clock format translates to 4:00 AM in civilian time. In this system, the first two digits represent the hour, while the last two digits represent the minutes. Since 0400 is less than 1200, it falls in the morning period of time. Therefore, 0400 hours simply means four o'clock in the morning in standard civilian time notation. Understanding this conversion is essential for effective communication, especially in contexts like dispatch, where precise time references are crucial.
