It is all three.
The number 12 is a natural number, a whole number, an integer, and a rational number. A natural number is a positive integer starting from 1, which includes 12. Whole numbers include all natural numbers along with zero, so 12 is also a whole number. Integers include all whole numbers along with their negatives, making 12 an integer. Lastly, a rational number is any number that can be expressed as a fraction, and 12 can be written as 12/1, making it a rational number.
Some definitions maintain that the set of whole numbers does not include negative numbers. That makes -12 an integer and rational.

12 is a rational number. Incidentally, there is no such time as 12 am or 12 pm: they are 12 noon and 12 midnight. Furthermore, if it was a time then it would not be a number (numbers do not have measurement units associated with them) and so it could not be rational.
Negative 12 itself is a rational number. It's the ratio of -12 to 1 .
