title: Yahoo Pandas datareader date difference
body: <p>I am trying to import stock data using Yahoo API as a source. I have tried it many times and I always get the same error, the start and end date are different from what I have passed. For example I pass the start and end date as <strong>'2015-1-1' &amp; '2017-1-1'</strong> but the stock data I get start and ends at <strong>'2014-12-31' &amp; '2016-12-30'</strong>. I dont know what I am doing wrong. I even tried using google but got a error as &quot;data_sorce='google' not implemented.&quot;
  Is there some other free data source I can use or correct the dates while using Yahoo?  <a href="https://i.stack.imgur.com/xt8hF.jpg" rel="nofollow noreferrer">Jupyter notebook</a></p>
