The simplest definition of "abstract noun" is an entity that is not perceivable by one of the five senses.
By that definition (and there may be better ones), the 24-hour day is an abstraction. However, day as the noun meaning the period of light between dawn and dusk, is certainly perceivable.
A smell is perceivable; the sense of smell is not.
Air is not perceivable if it is clean and not moving. However, it is composed of nitrogen, oxygen, water vapor, casrbon dioxide. It is difficult to consider something composed of matter to be an abstraction.
