Military time, also called the 24 hour clock has been around for a long time, but according to Wikipedia the U.S. Navy began using it in the 1920’s. The clock runs from midnight to midnight starting at 0000 hours and ending at 2359 hours.
So let’s start with the easy part. If you see 0100 which is pronounced “0h one hundred hours” or “zero one hundred hours” the time would be 1:00 a.m.; 0200 is 2:00 a.m. and so on up until noon which is 1200 hours, “twelve hundred hours.”
For example, if someone said “The recruit graduation starts at 0900.” You would know that means 9:00 a.m. If they said 0735 that would be 7:35 a.m. But once we get past 1259, the next number is 1300 hours which is pronounced “thirteen hundred hours.” and means 1:00 PM. 1400 hours is 2:00 p.m. and so on.
Since the time from 0100 to 1259 is the same time as 1:00 a.m. to 12:59 p.m., all you need to know is how to convert back to regular time from 1:00 p.m. until Midnight. How do we figure out what time to meet someone at the PX if they say, “Meet me by the coffee shop at fourteen forty. (1440)” The easiest way I found besides counting on my fingers (which I’ve done for a number of years) is to subtract 1200 from the time they give you. In our example, “meet me at the coffee shop at 1440”, take 1440 and subtract 1200 which equals 240 or 2:40 p.m.
Try it with the example in the first paragraph. “I’ll be back from the game around 1900 Mom.” Take 1900-1200 and you get 700 or 7:00 p.m. Write it out a few more times and you’ll sound like an old Hat * in no time. 🙂
