var b = moment([2011, 02, 17]);

var years = a.diff(b, 'year');

b.add(months, 'months');

var days = a.diff(b, 'days');

Answer 1

You can use moment duration format.

Include moment duration format plugin, and then..

var duration = moment.duration(a.diff(b));
console.log(duration.format('y [years] m [months] d [days]'));
