Get time difference between two date strings

Question

I want to develop a JavaScript function to calculate the activity of users based on the date in the server where the data is stored. The problem is that the date is a string like this:

2013-08-11T20:17:08.468Z

How can I compare two string like this to calculate minor and major time as in the example?

Answer 1

If you want to compare two dates just use this :

var dateA = '2013-08-11T20:17:08.468Z';
var parsedDateA = new Date(dateA).getTime();

var dateB = '2013-06-06T17:33:08.468Z';
var parsedDateB = new Date(dateB).getTime();

if(parsedDateA > parsedDateB) {
    // do something
}

Answer 2

Assuming you need to do the comparisons client-side, the best way is to load the dates into Date objects using Date.parse . Then compare them using the functions provided for Date , such as getTime .

Answer 3

Try parse method:

var s = "2013-08-11T20:17:08.468Z";
var d = Date.parse(s);

As I have understood you in the right way, there is a good answer to your question here .

You can also look at this very good Library ( DateJS ).
