moment difference code example

Example 1: moment js date diff

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = d.format("hh:mm:ss");

// outputs: "48:39:30"

Example 2: vue moment js difference between dates in minutes

var now  = "04/09/2013 15:00:00";
var then = "04/09/2013 14:20:30";

moment.utc(moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"))).format("HH:mm:ss")

// outputs: "00:39:30"

Example 3: calculate time difference in hrs moment

var duration = moment.duration(end.diff(startTime));
var hours = duration.asHours();

Example 4: moment js difference between two dates

var admission = moment('{date1}', 'DD-MM-YYYY'); 
var discharge = moment('{date2}', 'DD-MM-YYYY');
discharge.diff(admission, 'days');

Example 5: moment diff

var a = moment([2007, 0, 29]);
var b = moment([2007, 0, 28]);
a.diff(b, 'days') // 1
