Moment.js Get Difference Between Two Dates In The Dd:hh:mm:ss Format?

I am calculating the time until 11:59PM of the current day. Here is an example.

Solution 1:

You'll want to modify your now variable after each diff.

var hours = mid.diff(now, 'hours'); //Get hours 'till end of day
now.hours(now.hours() + hours);
var minutes = mid.diff(now, 'minutes');

Solution 2:

Just for comparison, here's David Stampher's moment.js example from a comment on another answer giving the time until 23:59:59.999 "today" and the same functionality in plain JS:

// Moment.js versionvar now = moment();
var mid = moment();
mid = mid.endOf('day');
var diff1 = moment.utc(moment(mid, "DD/MM/YYYY HH:mm:ss")
             .diff(moment(now, "DD/MM/YYYY HH:mm:ss")))
           .format("HH:mm:ss");

console.log('moment.js: ' + diff1);

// POJS versionvarz = (n) => (n<10? '0' : '') + n;
var ms = newDate().setHours(23,59,59,999) - newDate();
var diff2 = z(ms/3.6e6|0) + ':' +
            z(ms%3.6e6/6e4|0) + ':' +
            z(ms%6e4/1e3|0);

console.log('plain js : ' + diff2);
