list each clock hour between start and end of day moments 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: create moment duration

moment.duration(2, 'seconds');
moment.duration(2, 'minutes');
moment.duration(2, 'hours');
moment.duration(2, 'days');
moment.duration(2, 'weeks');
moment.duration(2, 'months');
moment.duration(2, 'years');
moment.duration('2', 'years'); // from 2.25.0

// or create from an object
moment.duration({
    seconds: 2,
    minutes: 2,
    hours: 2,
    days: 2,
    weeks: 2,
    months: '2',
    years: '2'
});

// or create from an iso 8601 string
moment.duration('P1Y2M3DT4H5M6S');
moment.duration('P1M');

// duration format strings with a space between days and rest is also supported.
moment.duration('7 23:59:59.999');
