title: Parsing Column names as DateTime
body: <p>Is there a way of parsing the column names themselves as datetime.? My column names look like this:</p>
  
  <pre><code>Name    SizeRank    1996-06    1996-07     1996-08    ...
  </code></pre>
  
  <p>I know that I can convert values for a column to datetime values, e.g for a column named datetime, I can do something like this:</p>
  
  <pre><code>temp = pd.read_csv('data.csv', parse_dates=['datetime'])
  </code></pre>
  
  <p>Is there a way of converting the column names themselves? I have 285 columns i.e my data is from 1996-2019.</p>
