Description

Issues and Milestones can get an Due date.
If the due date is set to the current day it gets supplemented by the text Overdue.
In listings Overdue entries get their Due-Date colored red.

In fact if something is overdue, it should have been done before now - if something is due today I still have time to do it 😄

My suggestion would be to call something overdue if it really was due to yesterday or before.
And I would suggest to add an additional state like Due today (which could be colored maybe yellow in listings)

This is because due dates are saved as unix timestamps. So when you save a due date for lets say the 21.12.2018, it is saved as 21.12.2018 00:00. So, if it's the 21.12.2018 15:00, it makes perfect sense to compare it that way. IMHO we should change it when saving.
