JAVASCRIPT getDay() METHOD

The getDay() method in javascript returns the day of the week as an integer from 0 through 6. Sunday has a value of 0 through to Saturday which has a value of 6.

The general format is:

dateObject.getDay();

If you want to return the day of the week with getDay() method, you will first have to create a new date object and then use the new date object with the getDay() method.

Example 1: Using getDay() for today:

<script type="text/javascript">

var dd=new Date(); // creates a new date object

dd=dd.getDay(); // returns the day of the week

document.write(dd); // outputs the day of the week as a number

</script>

The above will output:



Example 2: Using getDay() to get day of week of a specified date:

<script type="text/javascript">

var dd=new Date("January 16, 2008"); // creates a new date object

dd=dd.getDay(); // returns the day of week as a number

document.write(dd); // outputs the month

</script>

The above will output:



Example 3: Using getDay() and a switch statement to get the name of the day:

<script type="text/javascript">

var dd=new Date();

dd=dd.getDay();

switch(dd)
{
case (0):
var DAY="Sunday";
break;
case (1):
var DAY="Monday";
break;
case (2):
var DAY="Tuesday";
break;
case (3):
var DAY="Wednesday";
break;
case (4):
var DAY="Thursday";
break;
case (5):
var DAY="Friday";
break;
case (6):
var DAY="Saturday";
break;
}

document.write(DAY);

</script>
