What is the 24-hour time format for 4:00 PM?

The 24-hour time format is designed to represent time without the ambiguity of AM and PM, making it particularly useful in professional and medical settings. In this system, the day runs from 00:00 (midnight) to 23:59.

To convert 4:00 PM into the 24-hour format, one would add 12 hours to the standard 12-hour format time. Since PM hours are counted from 12:00 PM onward, 4:00 PM becomes 16:00 in 24-hour format.

Thus, the correct representation of 4:00 PM is expressed as 1600 in the 24-hour format. This system ensures clarity and helps avoid confusion, especially in contexts such as healthcare, where precise timing is crucial.
