In your header file, there is a script tag with the clock script in it. Use that for now, and eventually this will grow into a few different scripts as it becomes bigger. Let's get it started in an organized way; there's no sense in creating a debt of disorganization to clean up later.
In the beginning of the script, add a variable object named home:
var home = {};
Then, prepend all variables and functions following this with home instead of leaving them as newly defined. This adds them to that home object. This will prevent confusion and collisions later on. This looks like the following:
var home = {};
home.dayArray = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
home.monthArray = ["January","February","March","April","May","June","July","August","September","October","November","December"];
home.getTime = function(){
var today=new Date();
var h=today.getHours();
var m=today.getMinutes();
var s=today.getSeconds();
var d=home...
