Extension:Countdown


 * See Extension:EventCountdown for an updated and maintained extension.

Countdown is a MediaWiki 1.5, and up, extension that allows a wiki page to display one or more "live" countdowns (using DHTML) to a specified date. It is designed to allow the countdown text to be formatted using wiki syntax. Once it is installed you invoke it via the  countdown  tag which accepts two arguments; Withing the countdown opening and closing tags you'll have four extra markups you can use to place the countdown components: See below for some usage examples.
 * 1) time - this is the target time to count down to.
 * 2) name (optional) - used when there are more than one countdown on a page
 *  - days to target time
 *  - hours to target time
 *  - minutes to target time
 *  - seconds to target time

Caveats:
 * This plugin seems to be broken. Enabling this plugin in LocalSettings.php according to [the documentation for Extensions in the manual] causes an empty, white page to load instead of your wiki.  Don't bother trying to use it unless you are an expert with how MediaWiki works and are capable of fixing whatever is wrong.
 * The "time" attribute, while pretty flexible, must be written in some standard parseable form (parseable by javascript). Use the examples below and modify if you're not familiar with what formats that work.
