Answer by dheerendra for How do I get the difference between two Dates in JavaScript?

function compare(){  var end_actual_time    = $('#date3').val();  start_actual_time = new Date();  end_actual_time = new Date(end_actual_time);  var diff = end_actual_time-start_actual_time;  var diffSeconds = diff/1000;  var HH = Math.floor(diffSeconds/3600);  var MM = Math.floor(diffSeconds%3600)/60;  var formatted = ((HH < 10)?("0"+ HH):HH) +":"+ ((MM < 10)?("0"+ MM):MM)  getTime(diffSeconds);}function getTime(seconds) {  var days = Math.floor(leftover / 86400);  //how many seconds are left  leftover = leftover - (days * 86400);  //how many full hours fits in the amount of leftover seconds  var hours = Math.floor(leftover / 3600);  //how many seconds are left  leftover = leftover - (hours * 3600);  //how many minutes fits in the amount of leftover seconds  var minutes = leftover / 60;  //how many seconds are left  //leftover = leftover - (minutes * 60);  alert(days +':'+ hours +':'+ minutes);}
