How was 23:59 converted to 11:59 PM ?
1. Step One: To convert 23:59 (twenty-three fifty-nine) to 12-hour, firstly, we didn't convert the minutes, we leave it. In our case it will be ( :59 fifty-nine ). and we just convert the hours.
2. Step Two: If the number of hours on military time (24-hour system) that we need to convert it, is less than 12:00, it will be the same on regular time (12-hour system).
In our case,
It's 23 (eleven), so we subtract 12 from 23 then add PM like ( 23 - 12 ). It will be 11 PM. (11 PM means 11 in the noon).
The final result is:11:59 PM ( In words: eleven fifty-nine in the noon ). Look at the chart below.
