title: Carbon - get first day of month
body: <p>I am using carbon but trying to get the first day of the month so I can run a report from the beginning of the month till the current day.</p>
  
  <pre><code>    $date = [
          'start' =&gt; new \Carbon\Carbon('last month'),
          'end' =&gt; new \Carbon\Carbon('today')
      ];
  </code></pre>
  
  <p>The above code will show todays date back to same date in the previous month. But I want to get from the 1st to now.</p>
  
  <p>Is there an easy way to do this like I am above? Cant find anything in the docs.</p>
