title: Get Weeks In Month Through Javascript
body: <p>In Javascript, how do I get the number of weeks in a month? I can't seem to find code for this anywhere.</p>
  
  <p>I need this to be able to know how many rows I need for a given month.</p>
  
  <p>To be more specific, I would like the number of weeks that have at least one day in the week (a week being defined as starting on Sunday and ending on Saturday).</p>
  
  <p>So, for something like this, I would want to know it has 5 weeks:</p>
  
  <pre><code>S  M  T  W  R  F  S
  
           1  2  3  4
  
  5  6  7  8  9  10 11
  
  12 13 14 15 16 17 18
  
  19 20 21 22 23 24 25
  
  26 27 28 29 30 31 
  </code></pre>
  
  <p>Thanks for all the help.</p>
