How convert 11:59 pm to 24-hour (or military)?


1. Step One: To convert 11:59 pm (eleven fifty-nine pm) to 24-hour, should know that: when we're converting the time from a 12-hour clock to a 24-hour clock, we just convert the hours, in this example: 11 hr (eleven hours). And we leave the minutes and don't convert it. in the current example, it's 59 min (fifty-nine).


2. Step Two: If the time is "am" we leave the number of hours as is. And if the time is "pm" we add 12 to the hour.


In our case, it's 11 pm (eleven pm), So we will add 12 to the number of hours. like (11 + 12) = 23. The result is: 23:59 (twenty-three fifty-nine).
