Introduction:
In this article I am going to explain you about the date object which is used in Java Script. It is a Data type built into the Java Script language.
The date object in Java Script is basically used to work with date and time. A Date object is useful when we want to display a date or we have to perform some sort of calculation on timestamp then we need a date object. The Java Script simply accesses the system clock to get the date.
Date objects are created with the new Date(), once a date object is created then we can operate a number of methods on it they are simply used to get and set the year, month, day, time and so on.

Get current Date:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script type="text/javascript">
function getTodayDate() {
var date = new Date();
var day = date.getDate();
var year = date.getFullYear();
var month = date.getMonth() + 1;
document.write("Date is: " + date + "<br />");
document.write("Day is: " + day + "<br />");
document.write("Year is: " + year + "<br />");
document.write("Month is: " + month + "<br />");
}
</script>
</head>
<body onload="getTodayDate()">
</body>
</html>
Output :
In this example we have added 1 to month because we have to correct the problem of being January 0 and December 11.
Get Current Time:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script type="text/javascript">
function getTime() {
var date = new Date();
var hrs = date.getHours();
var min = date.getMinutes();
var sec = date.getSeconds();
document.write("Hours is: " + hrs + "<br />");
document.write("Minutes: " + min + "<br />");
document.write("Sec is: " + sec + "<br />");
}
</script>
</head>
<body onload="getTime()">
</body>
</html>
Output:
JavaScript Date Object

Through this article we came to know about the date object and how to use it in Java Script.
