What is Military Time?Military time is a way of expressing time that is used mainly by the military and other organizations that need to be precise about the time of day. It is based on a 24-hour clock that starts at midnight and goes up to 23:59, or 11:59 pm. While it may seem confusing at first, once you understand how it works, it’s easy to read and use.
Military time can be especially useful for those who work in fields where precision is important, such as emergency services or transportation. It can also help people keep track of their daily activities more easily than standard time. Understanding military time can also come in handy when traveling internationally, as many countries outside the US use this system.
