Example 1: momentjs number of days between two dates
var given = moment("2018-03-10", "YYYY-MM-DD");
var current = moment().startOf('day');
moment.duration(given.diff(current)).asDays();
Example 2: moment date difference in days
moment(new Date()).diff(moment(new Date()), 'days')
Example 3: how 2 subtract 2 dates using moment.js
var date1 = moment('2016-10-08 10:29:23');
var date2 = moment('2016-10-08 11:06:55');
var diff = date2.diff(date1);
Example 4: moment js between two dates
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);
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: 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 6: moment js date between two dates
target.isBetween(start, finish, 'days', '()')
target.isBetween(start, finish, 'days', '(]')
target.isBetween(start, finish, 'days', '[)')
target.isBetween(start, finish, 'days', '[]')
