The Date object is a datatype built into the JavaScript language. Date objects are created with the new Date( ) as shown below.
Once a Date object is created, a number of methods allow you to operate on it. Most methods simply allow you to get and set the year, month, day, hour, minute, second, and millisecond fields of the object, using either local time or UTC (universal, or GMT) time.
The setUTCMonth() function of the date object accepts an integer representing the month of the year and replaces the value of the month in the current date with it according to the universal time (0 represents January and so on...).
Its Syntax is as follows
dateObj.setUTCMonth();

<body>
<script type="text/javascript">
var dateObj = new Date('september 26, 89 12:4:25:96');
document.write("Current date: "+dateObj.toUTCString());
document.write("<br>");
dateObj.setUTCMonth(6);
document.write("Date after setting new month value: "+dateObj.toUTCString());
</script>
</body>
</html>
Current date: Tue, 26 Sep 1989 06:34:25 GMT Date after setting new month value: Wed, 26 Jul 1989 06:34:25 GMT
Though you do not mention the minutes of the day while creating the date object, You can still set it using the setUTCMonth() function.

<script type="text/javascript">
var dateObj = new Date('1989 5:4:25:96');

document.write(dateObj.toString());
</script>
</body>

In the same way, though you do not pass any value to the constructor while creating the date object still you can set the setUTCMonth() using this function and the date, year and, other values remain same as in the current date (and time).
