I have this killer javascript clock but I want to convert it to countdown to my Army deploy date. heres the code so far:

Code:

<html>
<head>
</head>
<body>
<script type="text/javascript">
function chkTime(){
	var today=new Date()
	var h=today.getHours()
	var m=today.getMinutes()
	var s=today.getSeconds()
	AMPM=checkAMPM(h)
	showAMPM = 'am'
	if (AMPM == true){
		h = h - 12
		showAMPM = 'pm'
	}
	m=checkTime(m)
	s=checkTime(s)
	document.getElementById('timedisplay').innerHTML=h+':'+m+':'+s+' '+showAMPM
	t=setTimeout('chkTime()',500)}
	function checkAMPM(h){if (h > 12){return true}else{return false}}
	function checkTime(i){
		if (i<10) {i='0' + i}
  	return i
	}
	<!--Set the Date to countdown to  -->
	var dd = '20071011'
        var dh = '12'
        var dm = '00'
        var ds = '00'
</script>
<div id="timedisplay">0:00:00 AM</div><script type="text/javascript">chkTime();</script></small><br />
</body>
</html>

I don't know how to figure the difference.

Try the script below, its very easy to use:

Create a .js file called countdown.js, drop in the following code:

Code:

*/

function calcage(secs, num1, num2) {
  s = ((Math.floor(secs/num1))%num2).toString();
  if (LeadingZero && s.length < 2)
    s = "0" + s;
  return "<b>" + s + "</b>";
}

function CountBack(secs) {
  if (secs < 0) {
    document.getElementById("cntdwn").innerHTML = FinishMessage;
    return;
  }
  DisplayStr = DisplayFormat.replace(/%%D%%/g, calcage(secs,86400,100000));
  DisplayStr = DisplayStr.replace(/%%H%%/g, calcage(secs,3600,24));
  DisplayStr = DisplayStr.replace(/%%M%%/g, calcage(secs,60,60));
  DisplayStr = DisplayStr.replace(/%%S%%/g, calcage(secs,1,60));

  document.getElementById("cntdwn").innerHTML = DisplayStr;
  if (CountActive)
    setTimeout("CountBack(" + (secs+CountStepper) + ")", SetTimeOutPeriod);
}

function putspan(backcolor, forecolor) {
 document.write("<span id='cntdwn' style='background-color:" + backcolor + 
                "; color:" + forecolor + "'></span>");
}

if (typeof(BackColor)=="undefined")
  BackColor = "white";
if (typeof(ForeColor)=="undefined")
  ForeColor= "black";
if (typeof(TargetDate)=="undefined")
  TargetDate = "12/31/2020 5:00 AM";
if (typeof(DisplayFormat)=="undefined")
  DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds.";
if (typeof(CountActive)=="undefined")
  CountActive = true;
if (typeof(FinishMessage)=="undefined")
  FinishMessage = "";
if (typeof(CountStepper)!="number")
  CountStepper = -1;
if (typeof(LeadingZero)=="undefined")
  LeadingZero = true;


CountStepper = Math.ceil(CountStepper);
if (CountStepper == 0)
  CountActive = false;
var SetTimeOutPeriod = (Math.abs(CountStepper)-1)*1000 + 990;
putspan(BackColor, ForeColor);
var dthen = new Date(TargetDate);
var dnow = new Date();
if(CountStepper>0)
  ddiff = new Date(dnow-dthen);
else
  ddiff = new Date(dthen-dnow);
gsecs = Math.floor(ddiff.valueOf()/1000);
CountBack(gsecs);

Put this code in your html where you want to display the countdown:

Code:

  <!--<script language="JavaScript">
                                TargetDate = "02/24/2007 9:00 AM";
                                BackColor = "black";
                                ForeColor = "#FFCC00";
                                CountActive = true;
                                CountStepper = -1;
                                LeadingZero = true;
                                DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds";
                                FinishMessage = "Your final message";
                                </script>
                                <script language="JavaScript" src="js/countdown.js"></script>-->

Good luck!
