Anything between 1201 and 2359 is basically "p.m." time. The "p.m." hours usually give people more trouble, but always remember that 1300 (said "thirteen-hundred") converts into 1 p.m. Therefore, 1400 converts into 2 p.m., 1500 converts into 3 p.m., and so on and so on. One of the main advantages of using military time is eliminating ambiguity. Military routines and operations demand precision, and the use of the 24-clock system prevents any confusion over a.m. After noon, instead of starting over with 1, military time continues chronologically, so that 1 p.m. Let us say, for example; you told your friend to meet her at 9. How would your friend know if you meant 9 am or 9 pm if you planned to meet up at 9? With military time, there is no ambiguity because 0900 means 9 in the morning, and 9 pm is 2100 hours. The 12-hour and 24-hour times are the same from midnight to noon. If the time is "AM," and the time is 1200 hours or later, add 2400 hours to the time to get the military time. If the time is "PM," add 1200 hours to the time to get the military time. We are committed to quality information, infographics, calculators, charts, and guides related to military time.
