moment get difference between two dates code example

Example 1: moment date difference in days

moment(new Date()).diff(moment(new Date()), 'days') // 0

Example 2: moment check days of difference between days

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

Example 3: 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 4: moment js between two dates

// moment version => 2.13.0.
const start = moment().subtract(1, 'days');
const end = new Date();
const actual = moment().subtract(1, 'hours');
const test = moment(actual).isBetween(start, end);
console.log(test);
  
// moment version < 2.13.0.
var startDate = new Date(2013, 1, 12)
  , endDate   = new Date(2013, 1, 15)
  , date  = new Date(2013, 2, 15)
  , range = moment().range(startDate, endDate);
range.contains(date);

Example 5: calculate time difference in hrs moment

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

Example 6: moment js difference between two dates

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