Except that years do actually form a sequence, and it's possible to
perform maths on them; for instances, subtracting one year from another
yields a duration[*1], which is a meaningful quantity, whereas
subtracting a couple of credit card numbers is completely useless.
[*1] Yes, there are exceptions. But there are still many situations
where this is useful, because of the context, such as the range of
possible years and the location.
