This code allows you to count down to certain dates, like Christmas, or your birthday. These are great for blogs!

Example:

All you have to do is copy this code and paste it where ever you want it:
<script language="JavaScript1.2"> /* Dynamic countdown Script- © Dynamic Drive (www.dynamicdrive.com) For full source code, 100's more DHTML scripts, and TOS, visit http://www.dynamicdrive.com */ function setcountdown(theyear,themonth,theday){ yr=theyear;mo=themonth;da=theday } //////////CONFIGURE THE COUNTDOWN SCRIPT HERE////////////////// //STEP 1: Configure the countdown-to date, in the format year, month, day: setcountdown(2005,12,25) //STEP 2: Change the two text below to reflect the occasion, and message to display on that occasion, respectively var occasion="Christmas!" var message_on_occasion="Merry Christmas!" //STEP 3: Configure the below 5 variables to set the width, height, background color, and text style of the countdown area var countdownwidth='480px' var countdownheight='20px' var countdownbgcolor='lightblue' var opentags='<font face="Verdana"><small>' var closetags='</small></font>' //////////DO NOT EDIT PASS THIS LINE////////////////// var montharray=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec") var crosscount='' function start_countdown(){ if (document.layers) document.countdownnsmain.visibility="show" else if (document.all||document.getElementById) crosscount=document.getElementById&&!document.all?document.getElementById("countdownie") : countdownie countdown() } if (document.all||document.getElementById) document.write('<span id="countdownie" style="width:'+countdownwidth+'; background-color:'+countdownbgcolor+'"></span>') window.onload=start_countdown function countdown(){ var today=new Date() var todayy=today.getYear() if (todayy < 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[mo-1]+" "+da+", "+yr dd=Date.parse(futurestring)-Date.parse(todaystring) dday=Math.floor(dd/(60*60*1000*24)*1) dhour=Math.floor((dd%(60*60*1000*24))/(60*60*1000)*1) dmin=Math.floor(((dd%(60*60*1000*24))%(60*60*1000))/(60*1000)*1) dsec=Math.floor((((dd%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1) //if on day of occasion if(dday<=0&&dhour<=0&&dmin<=0&&dsec<=1&&todayd==da){ if (document.layers){ document.countdownnsmain.document.countdownnssub.document.write(opentags+message_on_occasion+closetags) document.countdownnsmain.document.countdownnssub.document.close() } else if (document.all||document.getElementById) crosscount.innerHTML=opentags+message_on_occasion+closetags return } //if passed day of occasion else if (dday<=-1){ if (document.layers){ document.countdownnsmain.document.countdownnssub.document.write(opentags+"Occasion already passed! "+closetags) document.countdownnsmain.document.countdownnssub.document.close() } else if (document.all||document.getElementById) crosscount.innerHTML=opentags+"Occasion already passed! "+closetags return } //else, if not yet else{ if (document.layers){ document.countdownnsmain.document.countdownnssub.document.write(opentags+dday+ " days, "+dhour+" hours, "+dmin+" minutes, and "+dsec+" seconds left until "+occasion+closetags) document.countdownnsmain.document.countdownnssub.document.close() } else if (document.all||document.getElementById) crosscount.innerHTML=opentags+dday+ " days, "+dhour+" hours, "+dmin+" minutes, and "+dsec+" seconds left until "+occasion+closetags } setTimeout("countdown()",1000) } </script> <ilayer id="countdownnsmain" width=&{countdownwidth}; height=&{countdownheight}; bgColor=&{countdownbgcolor}; visibility=hide><layer id="countdownnssub" width=&{countdownwidth}; height=&{countdownheight}; left=0 top=0></layer></ilayer>

Some of these codes may be a bit confusing:
var occasion="Christmas!
The name of the Holiday/Day your counting to- ex: 'My birthday', 'Christmas', 'The Car Wash' ect.
var message_on_occasion="Merry Christmas!"
What you want the clock to say when it has reached the occasion.
