Example

The output of the code above will be:

Example 2

Now we will create an array to get our example above to write a weekday, and not just 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.getUTCDay()]); </script>

The output of the code above will be:

Today it is Saturday
