Example
Example 1
In this example, we will get the current day of the week as a number:
<script type="text/javascript"> var d=new Date() document.write(d.getDay()) </script>

Example 2
Now, we will create an array so that the above example outputs the name of the week instead of a number:
<script type="text/javascript">
var d=new Date()
var weekday=new Array(7)
weekday[0]="Sunday"
weekday[1]="Monday"
weekday[2]="Tuesday"
weekday[3]="Wednesday"
weekday[4]="Thursday"
weekday[5]="Friday"
weekday[6]="Saturday"
document.write("Today it is " + weekday[d.getDay()])
</script>Output:
Today it is Saturday
Returns the day of the week to the specified date according to local time.
Example:
<html>
<head>
<title>JavaScript getDay Method</title>
</head>
<body>
<script type="text/javascript">
var dt = new Date("December 25, 1995 23:15:00");
document.write("getDay() : " + dt.getDay() );
</script>
</body>
</html>This will produce the following results:
getDay() : 1
