Date.getUTCDay() function in JavaScript
The Date object is a data type 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 getUTCDay() function of the Date object returns the day of the week of its current date according to the universal time. (0 represents Sunday and so on...)
Syntax
Its Syntax is as follows
dateObj.getUTCDay();
Example
<html>
<head>
<title>JavaScript Example</title>
</head>
<body>
<script type="text/javascript">
var dateObj = new Date('september 26, 89 12:4:25:96');
document.write(dateObj.getUTCDay());
</script>
</body>
</html>Output
2
Example
If you do not mention the date of the month the getUTCDay() function considers it as the date is first and the day of the week is returned accordingly (based on universal time). For example we have mentioned the month as September 1989 and we haven’t mentioned the date so, by default it is considered that the date is 1 and since it is Thursday and since it is 5th day of the week this function returns 5.

<script type="text/javascript">
var dateObj = new Date('September, 1989 00:4:00');

</body>
</html>Output

Example
If you do not pass any value to the constructor while creating the date object then the getUTCDay() function returns the day of the week of the current date according to the universal time.
<html> <head> <title>JavaScript Example</title> </head> <body> <script type="text/javascript"> var dateObj = new Date(); document.write(dateObj.getUTCDay()); </script> </body> </html>
