title: Yahoo Finance API from date - to date query
body: <p>I would like to get a few days of historical data.  The following link works but seems to be a little weird. In this example I would like to get data from May 4, 2016 to May 6, 2016. I guess the Yahoo API value for the month is 0-11 and not 1-12. Seems to make sense anyway.</p>

  <p>This doesn't work.</p>
