If you wish a script in PHP that will countdown the time you can use the following code:
$dtt_end = new DateTime('January 3, 2030 2:00 PM'); // the date to count down $remain = $dtt_end->diff(new DateTime()); echo $remain->d . ' days, ' . $remain->h . ' hours';
So this is a simple refresh script that will show on the browser without any javascript, CSS or some other design….
If you wish something more complex you can start with this idea
