12:00 AM is midnight, written as 00:00 in 24-hour format. It marks the very start of a new day.
12:00 PM is noon, written as 12:00 in 24-hour format. It is the only PM hour that does not require adding 12.
For PM times, add 12 to the hour — except for 12 PM which stays as 12:00. For example, 3:00 PM becomes 15:00, and 11:30 PM becomes 23:30.
