JavaScript Date getTimezoneOffset() Method

  • Last Updated : 19 Oct, 2021
Geek Week

Below is the example of Date getTimezoneOffset() method. 
 

  • Example: 
     

javascript




<script>
 
    // If nothing is in parameter it takes
    // the current date while creating Date object
    var date = new Date();
     
    // Extracting the time difference between
    // UTC and local time
    var diff = date.getTimezoneOffset();
     
   //Printing on console
   document.write(diff);
 
</script>
  • Output: 
     
-330

The date.getTimezoneOffset() method is used to return the time difference between Universal Coordinated Time (UTC) and local time, in minutes. If your time zone is GMT+5, -300 (60*5) minutes will be returned. Daylight savings prevent this value from being constant.
Syntax: 
 

date.getTimezoneOffset()

Parameter: This method does not accept any parameter. 
Return Values: It returns a number representing the time difference between UTC and Local Time in minutes.
More codes for the above method are as follows:
Program 1: The date of the month should lie in between 1 to 31 because none of the months have a date greater than 31 that is why it returns NaN i.e, not a number because the date for the month does not exist. 
 

javascript




<script>
 
    // Taking the date while creating Date object
    var date=new Date('Aug 32 2018 5:30');
     
    // Extracting the timedifference between
    // UTC and local time
    var n=date.getTimezoneOffset();
    document.write(n)
 
</script>

Output: 
 

NaN

Program 2: In this example we will leave the new Date blank to get the time difference between UTC and local time by a trigger. 
 



javascript




<!DOCTYPE html>
<html>
    <head>

        <button onclick="gfg()">Click me</button>
 
        <script>
            function gfg() {
                // If nothing is in parameter it takes
                // the current date while creating
                // Date object
                var date = new Date("June 29 2020 10:30");
 
                // Extracting the time difference between
                // UTC and local time
                var diff = date.getTimezoneOffset();
 
                //Printing on console
                document.write(diff);
            }
        </script>
    </body>
</html>

Output:
