title: Create a timer countdown using hours, minutes & seconds from a future date
body: <p>I am using some code I found on the internet that creates a countdown from a certain date. I am trying to edit the code so that it only gives me a countdown from an hour, minute, and second that I specify from a future date. I cannot just have code that counts down from a specified time, I need it to countdown to a specified date in the future. This is important so that if the browser is refreshed the countdown doesn't start over but continues where left off. I will be using cookies so the browser remembers what future date was specified when it was first run.</p>
  
  <p>Here is the HTML:</p>
  
  <pre><code>&lt;form name="count"&gt;
  &lt;input type="text" size="69" name="count2"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>And here is the javascript:</p>
  
  <pre><code>window.onload = function()  {
  //change the text below to reflect your own,
  var montharray=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec")
  
  function countdown(yr,m,d){
  var theyear=yr; var themonth=m; var theday=d
  var today=new Date()
  var todayy=today.getYear()
  if (todayy &lt; 1000)
  todayy+=1900;
  var todaym=today.getMonth()
  var todayd=today.getDate()
  var todayh=today.getHours()
  var todaymin=today.getMinutes()
  var todaysec=today.getSeconds()
  var todaystring=montharray[todaym]+" "+todayd+", "+todayy+" "+todayh+":"+todaymin+":"+todaysec
  
  futurestring=montharray[m-1]+" "+d+", "+yr
  
  var dd=Date.parse(futurestring)-Date.parse(todaystring)
  var dday=Math.floor(dd/(60*60*1000*24)*1)
  var dhour=Math.floor((dd%(60*60*1000*24))/(60*60*1000)*1)
  var dmin=Math.floor(((dd%(60*60*1000*24))%(60*60*1000))/(60*1000)*1)
  var dsec=Math.floor((((dd%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1)
  if(dday==0&amp;&amp;dhour==0&amp;&amp;dmin==0&amp;&amp;dsec==1){
  document.forms.count.count2.value=current
  return
  }
  else
  document.forms.count.count2.value= dhour+":"+dmin+":"+dsec;
  setTimeout(function() {countdown(theyear,themonth,theday)},1000)
  }
  //enter the count down date using the format year/month/day
  countdown(2012,12,25)
  }
  </code></pre>
  
  <p>I am sure there is superfluous code above since I only need an hour, minute, and second that I would like to pass to the <code>countdown()</code> function. The year, month and day is unimportant but as I said this is code I am trying to edit which I found on the internet. Any help would be very appreciated. Thank you!</p>
