title: Show div once a day
body: <pre><code>&lt;div class="ads"&gt;Some text&lt;/div&gt;
  </code></pre>
  
  <p>Want to:</p>
  
  <ol>
  <li>show this block once a day per visitor (no registration) (hidden by default, cookie check, what should be used?)</li>
  <li>if block already was shown <strong>today</strong>, then don't show it <strong>today</strong> anymore</li>
  <li>if block was shown <strong>yeasterday</strong> and one day is past, then show it <strong>again</strong> (how to check properly that the one day is past?)</li>
  </ol>
  
  <p>How can I do this?</p>
