JavaScript getUTCDay(): Get UTC Day of the Week

The JavaScript getUTCDay() method is used to get the day of the week (0-6) according to Universal Time Coordinated (UTC) or Greenwich Mean Time (GMT). For example:

HTML with JavaScript Code
<!DOCTYPE html>
<html>
<body>
   
   <p id="xyz"></p>

   <script>
      const d = new Date();
      let day = d.getUTCDay();
      document.getElementById("xyz").innerHTML = day;
   </script>

</body>
</html>
Output

JavaScript getUTCDay() syntax

The syntax of the getUTCDay() method in JavaScript is:

x.getUTCDay()

where x must be an object of the Date() constructor.

The getUTCDay() method returns a number from 0 to 6, which indicates the day of the week.

Find the name of the UTC weekday in JavaScript

      <p>Today is <span id="res"></span></p>

      <script>
         const d = new Date();
         let day = d.getUTCDay();

         if(day==0)
            document.getElementById("res").innerHTML = "Sunday";
         else if(day==1)
            document.getElementById("res").innerHTML = "Monday";
         else if(day==2)
            document.getElementById("res").innerHTML = "Tuesday";
         else if(day==3)
            document.getElementById("res").innerHTML = "Wednesday";
         else if(day==4)
            document.getElementById("res").innerHTML = "Thursday";
         else if(day==5)
            document.getElementById("res").innerHTML = "Friday";
         else if(day==6)
            document.getElementById("res").innerHTML = "Saturday";
      </script>

</body>
</html>
Output

Today is

The same example can also be written as:

<!DOCTYPE html>
<html>
<body>
   
      <p>Today is <span id="res"></span></p>

      <script>
         const d = new Date();
         const weekday = ["Sunday", "Monday", "Tuesday", "Wednesday",
            "Thursday", "Friday", "Saturday"];
         document.getElementById("res").innerHTML = weekday[d.getUTCDay()];
      </script>

</body>
</html>

To get or print only three letters (first three letters) of the weekday, then replace the weekday array from the above example with:

const weekday = ["Sun", "Mon", "Tue", "Wed",
   "Thu", "Fri", "Sat"];
