With this plugin you can set up a countdown timer – or even multiple – on a page. The timer will count down until the given date and show the alternative content.
This plugin is great for use on sales pages and product launches or discounts, it gives a sense of tension to the visitor.
This plugin does not use an admin page, everything is done with a few simple shortcodes.
Usage:
<pre><code>[countdown date="18:00:00 08/30/2009"]
This page goes live in about: [counter]
[after]
Enter your secret content here
[/countdown]
</code></pre>
Note that dates are UTC and that alternative content is not send to the browser until the date passed.

WordPress Countdown Plugin

Add a countdown timer to any page hiding content until the date passes.
