JavaScript Date Refresh


New Coder

I have this code that displays current date and then also the current date plus 4 days. How do I get the plus 4 days date to refresh every second like the current time. When the time passes midnight and is a new day the plus 4 days date is not updating.


<!DOCTYPE html>

<script type="text/javascript">
function display_c(){
var refresh=1000; // Refresh rate in milli seconds

function display_ct() {
var strcount
var x = new Date()
document.getElementById('ct').innerHTML = x;

<body onload=display_ct();>
<h3>Today is:</h3>
<span id='ct' ></span>


<!DOCTYPE html>

<h3>ELITT Day is:</h3>
<p id="date"></p>

Date.prototype.addDays = function(days) {
var dat = new Date(this.valueOf());
dat.setDate(dat.getDate() + days);
return dat;

var dat = new Date();
document.getElementById("date").innerHTML = (dat.addDays(4));

Hey @gavin1f4.
There are quite a few errors in your code.

There can only be one of the <html>, <head> and <body> elements in a single HTML document. You have two html's and body's.

Your display_c() function seems to be that you're trying to run the display_ct() function every second?
There's a simple way to do that using the setInterval() method.

In your first <body> opening tag, you have the onload attribute, onload=display_ct();.
Although not required, I strongly recommend wrapping attribute values in either single or double quotes.
The semicolon is also not required here.

Try running your code in the W3 Validator and fixing the errors.
