I am trying to convert the number 20 into minutes with moment js. I need

21 to to look like 21:00

This way for my set interval the timer will show 19:58 to 0:01.

I had tried

  var x = 1260000;
  var d = moment.duration(x, 'milliseconds');
  var hours = Math.floor(d.asHours());
  var mins = Math.floor(d.asMinutes()) - hours * 60;

This still leaves me with 21. I am not sure how to get the minutes form.

This seems like it shoud be a short fix. Any help is greatly appreciated.

• You can do this without moment.js using the standard constructor: var d = new Date(year, month, day, hours, minutes, seconds, milliseconds); – Rob Commented Aug 29, 2016 at 9:41
• Could you give us what input you've got, and what output you're trying to get? It's quite hard to pick apart your code without the context. – Whothehellisthat Commented Aug 29, 2016 at 9:42
• Sorry if that isn't clear. I am trying get get the milliseconds to look like 21:00. I need a countdown to go to 0:01. However, i just keep getting 21 – Winnemucca Commented Aug 29, 2016 at 9:52

var number = 15;
moment(number.toString(),"LT")

output 15:00

other method var value = 6.8 (exemple : 34/5 (34 hours of work / 5 days)) /** * Convertion d'un nombre en Moment * @param value */ convertNumberToMoment(value: number): moment.Moment {

    var hours = Math.floor(value);
    var minutes = Math.round((value % 1)*100)/100;

    return moment(hours + ':' + minutes * 60 + '0',"LT");       
}

output 6:48

How to create a new moment object from hours-string and to display it as HH:MM :

var input = '21'; moment(input,'HH').format('HH:mm'); // 21:00

You can use moment-duration-format plug-in and duration subtract method.

The plug-in lets you format duration object and with the subtract method you can modify duration value.

Here a working example that may help you:

var $container = $('#timer');

var x = 1260000;
var d = moment.duration(x, 'milliseconds');

var intervalId = setInterval(function(){
  d.subtract(1, 's');
  if( d.seconds() >= 0 ){
    var timer = d.format('m:ss', { trim: false });
    $container.html(timer);
  } else {
    clearInterval(intervalId);
  }
}, 1000);

<script src="https://cdnjs.cloudflare./ajax/libs/moment-duration-format/1.3.0/moment-duration-format.min.js"></script>

<div id="timer"></div>

var moment = require("moment")
var x = 1260000;
var d = moment.duration(x, 'milliseconds');
moment(d.asMinutes(),'mm').format('mm:ss');
