title: Pandas matching rows by dates between 2 dataframes
body: <p>I have 2 dataframes.</p>
  
  <p>dfA has 848 rows</p>
  
  <p>dfB has 600 rows</p>
  
  <p>Both have Date column as Index.</p>
  
  <p>I want to find the 600 rows in dfA that match the dates in dfB -- dfA should end with 600 rows that match dfB. </p>
  
  <p>Trying something like below but isn't working...</p>
  
  <pre><code>dfA.iloc(dfB.index)
  </code></pre>
