Midnight is considered 12:00:00 AM and 00:00:00 on the 24-hour time clock. Noon is considered 12:00:00 PM and 12:00:00 on the 24-hour time clock. The easiest way to rationalize this is that 12:00, 12:01, 12:02 are the first minutes of the day and consecutive so they are all AM. The last minute and second of the day is 11:59:59 PM after which it becomes AM.
