Dynamic Countdown script belongs to the first type of count down script that lets you count down to relative events of a future date/time. This future date, while the same for everyone, occurs differently depending on the time zone they're in (ie: Christmas, your mom's birthday, April 1st 2015 etc). This script is extremely flexible- you can customize exactly how to display the output, or even specify a custom action to perform at the end of the countdown (ie: go to another page), by passing in your own custom format function.
