JavaScript Date Tutorial

JavaScript facilitates an object especially to get a day, a month, or a year as an output. This object is also called a JavaScript Date object.

JavaScript date object constructors

Date()  
Date(milliSeconds)  
Date(dateString)  
Date(year, month, day, hours, minutes, seconds, milliSeconds)

Example:

<html>
<body>
<script>
var date=new Date();
var day=date.getDate();
var month=date.getMonth()+1;
var year=date.getFullYear();
document.write("<br>Today Date: "+date);
document.write("<br>Day: "+day);
document.write("<br>Month: "+month);
document.write("<br>Year: "+year);
</script>
</body>
