Show div once a day
<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>
