Another thing that you could do is set up the switch statement like this:
switch(true){
case (day < 0 || day > 7):
statements;
case (day === 1):
statements;
...
}
Doing this allows you to set up each individual conditional statement as you would in an if block, giving you a little more freedom with your cases (although, at that point you may just want to use an if/else if/else chain)

You should probably, instead of if-statement, put that in your default case instead

Another thing you can do is making the days of the week be in an array and assume the array name is "day" as used by the author. you can easily call on the array on your switch statement. My own little understanding

Try this then......
function myFunction() {
var day;
switch (new Date().getDay()) {
case 0:
day = "Sunday";
break;
case 1:
day = "Monday";
break;
case 2:
day = "Tuesday";
break;
case 3:
day = "Wednesday";
break;
case 4:
day = "Thursday";
break;
case 5:
day = "Friday";
break;
case 6:
day = "Saturday";
break;
default:
day = "Unknown Day";
}
document.getElementById("txt").innerHTML = "Today is " + day;
}

And this to your HTML line...

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<p>As soon as you click on the "Click me" button, you see the result</p>
<button onclick="myFunction()">Click me</button>
<p id="txt"></p>
</body>
</html>
