iCalendar feeds are available for each of your lists.
If the iCalendar feed does not open in your calendar app automatically, you may need to copy-and-paste the iCalendar service's URL into the app.
Calendar apps will normally only display events (and not tasks) on the calendar. For this reason, the Remember The Milk iCalendar service can export tasks as events so that they will show on your calendar. Only tasks with due dates will be shown as events.
To use this service, click on the 'iCalendar (Events)' link.
