Explanation / Answer

Yes.

Why?

We set an example. If we compare January 17 and January 18, the "18" does not signify a larger quantity than the "17", but simply a number being next to 17.

The same goes for month.

Thus, month and day can be considered ordered factors, rather than numeric variables.
