Here is an example of JavaScript date. This JavaScript program will print the today's date and the current time as output:
<!DOCTYPE html>
<html>
<head>
<title>JavaScript Date Example</title>
</head>
<body>
<script type="text/javascript">
var today_date_var = new Date();
document.write("Today's date is: <b>" + today_date_var.getDate() + "/" + (today_date_var.getMonth()+1) + "/" + today_date_var.getFullYear() + "</b><br/>");
document.write("The time is: <b>" + today_date_var.getHours() + ":" + today_date_var.getMinutes() + ":" + today_date_var.getSeconds() + "</b><br/>");
</script>
</body>
</html>
Here is the output produced by the above JavaScript date example program:
Here is the live demo output produced by the above Date object example in JavaScript. You will watch today's date and current time as output.
