1. javascript difference between two dates in days

Here, we will create a javascript that is used to calculate the difference between two dates in days.

Use the given below function, To calculate the difference between 2 dates and get difference days.

    function daysDiff(dt1, dt2) 
     {

      // calculate the time difference of two dates JavaScript
      var diffTime =(dt2.getTime() - dt1.getTime());
  
      // calculate the number of days between two dates javascript
      var daysDiff = diffTime / (1000 * 3600 * 24); 

      return daysDiff;
      
     }

Ex:-

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>calculate difference between two dates in days javascript</title>

      // calculate the time difference of two dates JavaScript
      var diffTime =(dt2.getTime() - dt1.getTime());
  
      // calculate the number of days between two dates javascript
      var daysDiff = diffTime / (1000 * 3600 * 24); 

      return daysDiff;
      
     }

    dt1 = new Date("2019-11-27");
    dt2 = new Date("2019-11-29");

    var days = daysDiff(dt1, dt2)
    document.write( "calculate difference between two dates in days javascript :- " + days ); 

  </script>  
</body>
</html>

2. Calculate the difference between two dates in hours javascript

Next, we will create a javascript that is used to calculate the difference between two dates in hours.

    function hoursDiff(dt1, dt2) 
     {

      // calculate the time difference of two dates JavaScript
      var diffTime =(dt2.getTime() - dt1.getTime());
  
      // calculate the number of days between hours dates javascript
      var hoursDiff = diffTime / (1000 * 3600); 

      return hoursDiff;
      
     }

Ex:-

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>calculate difference between two dates in hours javascript</title>

      var diffTime =(dt2.getTime() - dt1.getTime());
  
      // calculate the number of days between hours dates javascript
      var hoursDiff = diffTime / (1000 * 3600); 

      return hoursDiff;
      
     }

    dt1 = new Date("2019-11-27");
    dt2 = new Date("2019-11-29");

    var hours = hoursDiff(dt1, dt2)
    document.write( "calculate difference between two dates in hours javascript :- " + hours ); 

  </script>  
</body>
</html>

Result Of the above code is: 48 hours

3. javascript difference between two dates in minutes

Now, we will create a javascript that is used to calculate the difference between two dates in minutes.

Use the given below function, to get the difference between 2 dates and get difference minutes.

    function minutesDiff(dt1, dt2) 
     {

      var diffMin =(dt2.getTime() - dt1.getTime()) / 1000;
      diff /= 60;
      return Math.abs(Math.round( diffMin ));
      
     }

Ex:-

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>calculate difference between two dates in minutes javascript</title>
</head>
<body>
  <script type = "text/javascript">
    function minutesDiff(dt1, dt2) 
     {

      var diffMin =(dt2.getTime() - dt1.getTime()) / 1000;
      diff /= 60;
      return Math.abs(Math.round( diffMin ));
      
     }

    dt1 = new Date("2019-11-27");
    dt2 = new Date("2019-11-28");

    var minutes = minutesDiff(dt1, dt2)
    document.write( "calculate difference between two dates in minutes javascript :- " + minutes );
