How to filter my tasks by date

This can be done from the "All Tasks" view.

Do the following:

Select All Tasks
Choose the multi-column button outlined in my screenshot.
Select the small magnifying glass to filter your tasks for all tasks that have a "status" that "is not" "done" (Highlighted in the screenshot)
Then right-click or secondary click on the header to choose the "due date" option to sort your list. (Highlighted in the screenshot)
Select the due date option in the header to sort by the due date.
