count up script

[Skavenger]

I found a script for showing the date and time since the forum came online, but it does not show the months, can anybody make this for me? I don't know javascript

I only want to display years, months and days

here is the code

<script type="text/javascript" language="JavaScript">

//modified by Feckie December 10th 2005 (to show years)

//modified by Feckie Jan 18th 2006 
	//fixed years problem
	//rewrite math
	//account for leapyear
	//account for year/years text




/* ?![CDATA[ */
function setcountup(theyear,themonth,theday){
yr=theyear;mo=themonth;da=theday
}
//////////CONFIGURE THE countup SCRIPT HERE//////////////////
//STEP 1: Configure the date to count up from, in the format year, month, day:
//This date should be less than today

setcountup(2004,10,24)

//STEP 2: Configure text to be attached to count up
var displaymessage="since $vboptions[bbtitle] - Forums came online!"
//STEP 3: Configure the below 5 variables to set the width, height, background color, and text style of the countup area
var countupwidth='95%'
var countupheight='20px' //applicable only in NS4
var countupbgcolor='alt1'
var opentags='<span class="smallfont">'
var closetags='</span>'
//////////DO NOT EDIT PASS THIS LINE//////////////////
var montharray=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec")
