Is there any way to get the difference between two datetime in moment.js

Question

Let's Say, I've a two datetime moment date time object.

momentdatefirst = '2017-03-21T05:00:00+05:45'

momentdatesecond = '1990-03-21T07:12:45+05:45'

How do calculate the difference between these two time stamps in moment.js?

I tried this:

var diff_hour = momentdatefirst.diff(momentdatesecond);

And this doesn't retrieve the actual difference.

Sorry, My bug was not because of the diff method but due to the two different date format between first and second date. Sorry — user2906838, Mar 21 '17 at 08:42

You should do it like this:

let date = moment('2017-03-21T05:00:00+05:45');
let dateTwo = moment('1990-03-21T07:12:45+05:45');
let diff = dateTwo.diff(date); // in milliseconds
let diffInHours = date.diff(dateTwo, 'hour'); // in hours
// and so on
console.log('diff in milliseconds', diff);

It will output 852068835000 milliseconds which ~ 27 years.

var a = moment('2016-06-06T21:03:55');//now
var b = moment('2016-05-06T20:03:55');

console.log(a.diff(b, 'minutes')) // 44700
console.log(a.diff(b, 'hours')) // 745
console.log(a.diff(b, 'days')) // 31
console.log(a.diff(b, 'weeks')) // 4
