Unless you decide that subtraction is between days' ends. Or days' beginnings. Either suffices to produce a 1-day result in that case, and is still consistent with viewing days as slices of time.

So you're deciding that a 'date' is 'the entire of that day', except when you subtract two of them, when it suddenly means something else? ;-)
