The new year means tax returns, renewal of business insurance and HR benefits, health-conscious lifestyle changes AND website footer updates! Oh No! You haven't updated your footer copyright date in how many years?
Here's the php code to add in to your site. <?php echo date("Y") ?>
So your code might look like this.
And you can edit it to look like this so the current year will always appear following the dash.
<p> Copyright © 2010-<?php echo date("Y") ?></p>
A small detail but one that professionals will notice.
