How to properly add 1 month from now to current date in moment.js

Question

I read the documentation of moment.js that if you want to add 1 month from the current date time you use this code

var moment = require('moment'); var futureMonth = moment().add(1, 'M').format('DD-MM-YYYY'); 

But the problem right now, it is not properly add the date correctly, for example let say the current date is 31/10/2015, explain in code

var currentDate = moment().format('DD-MM-YYYY'); var futureMonth = moment().add(1, 'M').format('DD-MM-YYYY');  console.log(currentDate) //  Will result --> 31/10/2015 console.log(futureMonth) //  Will result --> 30/11/2015  

if you take a look at the current calendar time, 1 month from 31/10/2015 supposed to be 1/12/2015

Could anyone give me some opinion on how to fix this problem.

Thank you

Answer 1

var currentDate = moment('2015-10-30'); var futureMonth = moment(currentDate).add(1, 'M'); var futureMonthEnd = moment(futureMonth).endOf('month');  if(currentDate.date() != futureMonth.date() && futureMonth.isSame(futureMonthEnd.format('YYYY-MM-DD'))) {     futureMonth = futureMonth.add(1, 'd'); }  console.log(currentDate); console.log(futureMonth);

EDIT

moment.addRealMonth = function addRealMonth(d) {   var fm = moment(d).add(1, 'M');   var fmEnd = moment(fm).endOf('month');   return d.date() != fm.date() && fm.isSame(fmEnd.format('YYYY-MM-DD')) ? fm.add(1, 'd') : fm;   }  var nextMonth = moment.addRealMonth(moment());
