You can easily add a due date to all your stickies, either with drag & drop from the calendar (which can be opened by clicking on the button in the top right corner of your board) or with a right mouse click (“Set Due Date”).
One of the filter options in the Filter Bar allows you to filter your stickies according to due date. You can select multiple dates at the same time (keep the shift or strg key pressed), e.g. a whole week or month at once.
The due date can be changed in the Lens and the Task List as well.
