Military time is standard and leaves no room for error. This is the reason why it is used for all major emergency services in the U.S. and Canada. Where this gets confusing is when you have to translate to the current time in your location. The East Coast of the United States is five hours later than Greenwich Mean Time. So, 1300Z at GMT is the same as 0800 on the East Coast. And p.m., which are two 12-hour blocks of the day denoting morning and afternoon or evening. Also, mankind tends to laugh about everything and military time wasn’t left without the attention of internet users. For example, 0930 should be read as “zero nine thirty”. And if the number is “round” like 0800, we should read it as “zero eight hundred”. From here, personnel must translate this time into their own time zone. Additionally, the abbreviated format of the 24-hour system makes it easier to send concise communications. When it comes to military drills and critical missions, the efficiency and accuracy of the 24-hour system can actually mean life or death. Check this guide if you still wondering what is 1200 in military time. The most important part of the 24 hour clock is to know whether we’re talking about AM or PM. The U.S. Army didn’t officially adopt military time until 1942.
