Solution 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());

Solution 2

According to the latest doc you can do the following-

Add a day

moment().add(1, 'days').calendar();

Add Year

moment().add(1, 'years').calendar();

Add Month

moment().add(1, 'months').calendar();

Solution 3

startDate = "20.03.2020";
var newDate = moment(startDate, "DD-MM-YYYY").add(5, 'days');
console.log(newDate)

Solution 4

You could try

moment().add(1, 'M').subtract(1, 'day').format('DD-MM-YYYY')

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.

  I got the idea from the current calendar time, if thats what you are asking for.

  I guess what you're looking for is moment().add(30, "days").

  @Gesper I thought moment.js define the month by itself without me needing to define it.

  @VikramDeshmukh I could do that, but it won't be flexible.

  @Jamiec Where is your answer, seems like you have taken it down?

  What is the rule that you actually want? Is it "Add the number of days in the current month"? Is it "Add 1 month + 1 day"?

  seems like the definition in momentjs is that if you have end-of-month and add 1 month, it will do end-of-next-month. Which seems very sane and predictable to me

  @JackMoscovi check my answer, I updated it so that it fits your needs.

  A month is not always 30 days long, so moment().add(30, "days") isn't technically the right answer.

  Please do not call not proper things as proper. I suggest to change title of the question somehow. Currently it is misleading.

  Change the title to "How to add a month to end of the current month?" Your expected behaviour is NOT proper and title is misleading.

  @JackMoscovi, There has to be weird boundary conditions around month addition. 2015-10-31 + 1 month I think should be in November.(Otherwise, it might feel like 2 months to some). If you insist that two consecutive days should not have the same "one more month day"), then I would ask you what 2015-01-31 + one month is compared to 2015-02-01 + one month should be.

Just wondering is this code flexible? or its just fix the current date problem 31/10/2015 - 1/12/2015?

This just goes wrong another way - July & August both have 31 days. When you add one month to July 31st you'll get 1st September.

Wow I tested on the last of January which is 31 and it works perfectly. Thanks!

this answer is wrong and does not correctly add a month according to the request above

While this code may answer the question, providing additional context regarding how and/or why it solves the problem would improve the answer's long-term value.

Try moment('2020-03-30').add(1, 'months') and then compare with moment('2020-03-31').add(1, 'months'). The result will be the same, which is wrong.
