title: How to validate AM/PM on Laravel5?
body: <p>I'm looking for validate 12 hours.
  A.M. 00:00 ~ 11:59 and P.M. 12:00 ~ 23:59.</p>
  
  <p>Input value come like this.</p>
  
  <pre><code>&lt;input type="text" name="am" value="00:00" /&gt;
  &lt;input type="text" name="am" value="11:59" /&gt;
  
  &lt;input type="text" name="pm" value="12:00" /&gt;
  &lt;input type="text" name="pm" value="23:59" /&gt;
  </code></pre>
  
  <p>So I made validate like this.</p>
  
  <pre><code>'am' =&gt; ['regex:/^(1[01]|0[0-9]):[0-5][0-9]$/'],
  'pm' =&gt; ['regex:/^(2[0-3]|1[2-9]):[0-5][0-9]$/'],
  </code></pre>
  
  <p>Does Laravel have any good validation without regex? (like after:tomorrow)
  I don't wanna use regex that make code difficult to reading comprehension.
  Any Ideas?</p>
