This site takes your trello cards and creates an iCalendar feed by their due date that you can plug into Google Calendar, Outlook and many others. The feed can be customized by choosing which board to take cards from, choosing meeting length for each card and more.
The first step is to authorize this app by clicking on the big button. All this app needs is read only permissions to read the due dates.
