I am trying to get days difference between two dates using Javascript.
using getTime() function, getting milliseconds and this is my code.

JavaScript

function daysdifference(date1, date2) {
            // The number of milliseconds in one day
            var ONEDAY = 1000 * 60 * 60 * 24;
            // Convert both dates to milliseconds
            var date1_ms = date1.getTime();
            var date2_ms = date2.getTime();
            // Calculate the difference in milliseconds
            var difference_ms = Math.abs(date1_ms - date2_ms);

            // Convert back to days and return
            return Math.round(difference_ms/ONEDAY);
        }

Not getting accurate result. This method seems not working. am i doing some mistake?
Is there any other better approach to have days difference?
Thanks

e.g. if i pass 2014-08-01 as date1 and 2014-08-26 as date2 its not working but if i do it like
date1 = new Date(2014, 0, 1); // any custom date
date2 = new Date() //Today date

then its working. my req is to pass custom date as user input

JavaScript

var date1 = new Date("7/11/2010");
var date2 = new Date("12/12/2010");
var timeDiff = Math.abs(date2.getTime() - date1.getTime());
var diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24)); 
alert(diffDays);

You could use momentjs, it calculates differencies and much more, if you're dealing with dates it can be helpful :)

Solution 2

Please check once this way,

C#

var startDate = Date.parse("2014-08-01");
            var endDate = Date.parse("2014-08-26");
            var timeDiff = endDate - startDate;
            daysDiff = Math.floor(timeDiff / (1000 * 60 * 60 * 24));

will it work with any date format?

Sanchayeeta 27-Aug-14 3:32am

This will take Date as yyyy-MM-dd ,yyyy/MM/dd format, yyyy,MM/dd format.

Yeah i see that. my req. was to pass any date format, any ways i made separate function to convert date in this format and then find the days difference with ur logic.
Thanks
