Calculating the difference between two dates in JavaScript

Hi guys, 
Some day ago i want a difference between two dates to check it's greater or less then..
After searching i got many solutions but best and easy solution it's here...

var dp_b_d = document.getElementById('dp_birth_date').value; 

// Get like 12/04/1990 date format  // Or if u have different format then u should convert it or get it by this link Click Here

var dp_d_d = document.getElementById('dp_death_date').value;

// Get like 15/04/1990 date format

var myDateArray = dp_d_d.split("/");  

var myDateArray2 = dp_b_d.split("/");

// Split it by using "/"  if your date format '15.04.1990' then split with '.'[dot] 

var EndDate = new Date(myDateArray[2],myDateArray[1],myDateArray[0]);
// Always pass this type value in Date(YEAR, MONTH, DATE)  

var Today = new Date(myDateArray2[2],myDateArray2[1],myDateArray2[0]);

  

var ONE_DAY = 1000 * 60 * 60 * 24;

var date1_ms = EndDate.getTime();
var date2_ms = Today.getTime();
// Convert both dates to milliseconds
 
var difference_ms = date1_ms - date2_ms;

var total_days =  difference_ms/ONE_DAY;
// Get difference in total days.

return total_days; 
// Here it's return 3days in this example.
