+1 I have been saying this since years, as long time Mentor of many nobles, who had quite some logic problems to get this right first.
It would make much more sense to see the day where you get taxes, not where realm collection is, as realm collection does not have any active effect on nobles.
That means it should go like: "Next taxes will be recieved in 7,6,5...days".
Now it starts with 6 days and the tomorrow/today thing is very confusing, even for old players it seems.
