How to do a date countdown (to a future date)? How would one go about doing a date countdown (something like this: https://www.mupromo.com/?kbid=4722). I know I'd need to create a block...and I have boilerplate code for that, but I was wondering whether there's a module that already does something similar...or any other pointers you can give.
The Countdown module has a drupal 6 &amp; 7 version. This may work for you. Here is a quote about it (from the module's project page):

Adds a block titled &quot;Countdown&quot; to count the days, hours, minutes, and seconds since or until a specified event. Can configure to just show days, or days and hours, etc.
