In 24-hour time, what does 10:00 PM correspond to?

In 24-hour time notation, hours are represented from 00:00 (midnight) to 23:59. Specifically, 10:00 PM is depicted in this format as 22:00. This is because, in the 24-hour system, you add 12 to the hours for any time from noon onwards, meaning 10:00 PM (which is 10 hours past noon) corresponds to 22:00.

This transformation of time helps eliminate confusion between AM and PM times in various settings, such as clinical environments or military contexts.
