Countdown to a specific date? (days until event)

Hi again :D

Ok, here's what I need :D First of all, my site is using CS4 and Actionscript 2. ( www.questformoreglory.com ). There's an important event that I want to put a countdown to, so that the people visiting the site, will know how many days are left till that event happens.

Anybody know how I can do this? :)
