Estou com uma duvida para desenvolver um contador regessivo é so vocês pra me salvar, rsrsrs.
É o seguinte, estou precisando de um contador que compare duas datas, data inicial e data final, e faça uma uma contagem regressiva entre as datas. Ex: Faltam 10d 08h 05m 33s.
Achei o código abaixo na net ele e muito bom porém a data de entrada é um "new Date()", eu gostaria de alterar esta data para uma data fixa.

//////////CONFIGURE THE COUNTDOWN SCRIPT HERE//////////////////
//STEP 1: Configure the countdown-to date, in the format year, month, day, hour(0=midnight,23=11pm), minutes, seconds:
setcountdown(2010,12,15,21,30,00)
//STEP 2: Change the two text below to reflect the occasion, and message to display on that occasion, respectively
var occasion="Comets vs Flyers game"
var message_on_occasion="Go Comets Go Go Go!"
//STEP 3: Configure the below 5 variables to set the width, height, background color, and text style of the countdown area
var countdownwidth='550px'
var countdownheight='35px'
var countdownbgcolor='lightblue'
var opentags='<font face="Verdana" color="blue"><small>'
var closetags='</small></font>'
