A task deadline may be set, changed and deleted again using Change Deadline or File Change Deadline in the task view. When filling in the deadline date fields, use YYYY-MM-DD date format. Entering a void date field deletes the deadline if present. Changing the task deadline is possible unless the task has reached a final status (accepted or cancelled). When the deadline has passed and the task has not been finished, the deadline is displayed in red in the task view.
