For hours above 12, subtract 12 from the hour, keep the minutes, and use PM: 22 − 12 = 10, so 22:00 = 10:00 PM.
To convert 10:00 PM back to 24-hour time, replace hour 12 with 0, then add 12 for PM or leave it unchanged for AM. Keep the minutes to get 22:00.
Remove the colon from the 24-hour time, keeping two digits each for hours and minutes: 22:00 → 2200. This represents a clock time, not a duration of 2200 hours.
