title: Get current month/year and next month/year?
body: <p>I'm trying to pull all billing info that has fields matching the current month/year or the next month year.</p>
  
  <p>For instance, say the current month was December 2014, I'd want something like this:</p>
  
  <pre><code>Billing.where(exp_month: 12, exp_year: 2014 OR exp_month: 1, exp_year: 2015)
  </code></pre>
  
  <p>That syntax is obviously incorrect, but it gives you an idea of what I'm after.</p>
  
  <p>So, the questions here are...</p>
  
  <ol>
  <li>How do I format that query correctly?</li>
  <li>How do I get the current/next month/year for that query format?</li>
  </ol>
  
  <p>I'm running Ruby 2.1.2.</p>
