JavaScript Date getUTCDay() Method

The date.getUTCDay() method is used to fetch the day of a week according to universal time from a given Date object (ranging from 0 to 6, where 0 represents Sunday).

Syntax:

DateObj.getUTCDay();

Parameter: This method does not accept any parameter. It is just used along with a Date Object from which we want to fetch the date of the month according to universal time.

Return Values: It returns the date of the month for the given date object according to universal time. The date of the month is an integer value ranging from 1 to 31.

Example 1: Below is an example of the Date getUTCDay() method. 

javascript

<script>
    // If nothing is in parameter it takes
    // the current date while creating Date object
    var date = new Date();

    // Date of the month from above date object
    // is being extracted using getUTCDay().
    var getUTC = date.getUTCDay();

    // Printing day of the week
    console.log(getUTC);
</script>

Output:

1

Example 2: The date of the month should lie between 1 to 31 because none of the months have a date greater than 31 that is why it returns NaN i.e, not a number because the date for the month does not exist. 

javascript

<script>
    // Here a date has been assigned according
    // to universal time while creating a Date object
    var dateobj =
    new Date('October 33, 1996 05:35:32 GMT-11:00');

    // date of the month from above date object
    // is being extracted using getUTCDay().
    var B = dateobj.getUTCDay();

    // Printing day of the week
    console.log(B);
</script>

Output:

NaN

Example 3: If the date of the month is not given then by default getUTCDay() function returns 1 according to universal time. It is an exceptional case. 

javascript

<script>
    // Here a date has been assigned according to
    // universal time while creating Date object
    var dateobj =
    new Date('October 1996 05:35:32 GMT-11:00');

    // date of the month from above date object is
    // extracted using getUTCDay().
    var B = dateobj.getUTCDay();

    // Printing day of the week
    console.log(B);
</script>

Output:

2
