How to use due dates in Kanban Tool?
To use a due date field on your Kanban cards, first make sure the field is enabled in Settings - Card Template, accessible from your board view.
Once selected as part of your Card Template, a due date field will be visible on task cards:
You can also see the due date without opening the task - it will appear when you hover the mouse pointer over the calendar icon. Also, when the due date has 9 or fewer days to go, the remaining number of days will display right next to the calendar icon.
Once the date is up, there will be a distinct red “0” or “- # days” staring at you from the card.
Due dates are also marked in the Calendar Widget (when enabled from Settings - Power-Ups).
