Add a duration to a moment (moment.js)

Question

Moment version: 2.0.0

After reading the docs, I thought this would be straight-forward (Chrome console):

var timestring1 = \"2013-05-09T00:00:00Z\";
         


        

Answer 1

For people having a startTime (like 12h:30:30) and a duration (value in minutes like 120), you can guess the endTime like so:

const startTime = '12:30:00';
const durationInMinutes = '120';

const endTime = moment(startTime, 'HH:mm:ss').add(durationInMinutes, 'minutes').format('HH:mm');

// endTime is equal to "14:30"
