Hello! I'm trying to figure how can I know the number of days the task was late or completed in advance for a given card. Let's suppose that I set a due date and when I mark it as completed (or move it to a list "Completed"), I'd like to know how many days it was late or early based on that due date.
I know that there power ups that can actually do this, but for this moment I'm trying to find a way that is free. The best free alternative I could find was the "Card Age Badge" power up, where it starts to count the age of the card since it was created. I wanted it to stop counting when it was moved to "Completed" list and then check how many days it took and how it compares to the due date.
