As of moment 2.8.4 - use .add(5, 'd') (or .add(5, 'days')) instead of .add('d', 5)
var new_date = moment(startdate, "DD-MM-YYYY").add(5, 'days');
Thanks @Bala for the information.

This is what you'd have to do to get that format.
startdate = "20.03.2014";
var new_date = moment(startdate, "DD-MM-YYYY").add('days', 5);
var day = new_date.format('DD');
var month = new_date.format('MM');
var year = new_date.format('YYYY');
alert(day + '.' + month + '.' + year);

You're not telling it how/what unit to add. Use -
var new_date = moment(startdate, "DD-MM-YYYY").add('days', 5);
Solution 2 - Javascript
moment(moment('2015/04/09 16:00:00').add(7, 'd').format('YYYY/MM/DD HH:mm:ss'))
has to format and then convert to moment again.
Solution 3 - Javascript
The function add() returns the old date, but changes the original date :)
startdate = "20.03.2014";
var new_date = moment(startdate, "DD.MM.YYYY");
new_date.add(5, 'days');
alert(new_date);
Solution 4 - Javascript
You can add days in different formats:
// Normal adding
moment().add(7, 'days');
// Short Hand
moment().add(7, 'd');
// Literal Object
moment().add({days:7, months:1});
See more about it on Moment.js docs: https://momentjs.com/docs/#/manipulating/add/
Solution 5 - Javascript
var end_date = moment(start_date).clone().add(5, 'days');
Solution 6 - Javascript
If we want to use the current date or present date:
var new_date = moment(moment(), "MM-DD-YYYY").add(7, 'days')
alert(new_date);
Solution 7 - Javascript
To get an actual working example going that returns what one would expect:
var startdate = "20.03.2014";
var new_date = moment(startdate, "DD.MM.YYYY");
var thing = new_date.add(5, 'days').format('DD/MM/YYYY');
window.console.log(thing)
Solution 8 - Javascript
- add https://momentjs.com/downloads/moment-with-locales.js to your html page
var todayDate = moment().format('DD-MM-YYYY');//to get today date 06/03/2018 if you want to add extra day to your current datethenvar dueDate = moment().add(15,'days').format('DD-MM-YYYY')// to add 15 days to current date..
point 2 and 3 are using in your jquery code...
Solution 9 - Javascript
You can reduce what they said in a few lines of code:
var nowPlusOneDay = moment().add('days', 1);
var nowPlusOneDayStr = nowPlusOneDay.format('YYYY-MM-DD');
alert('nowPlusOneDay Without Format(Unix Date):'+nowPlusOneDay);
alert('nowPlusOneDay Formatted(String):'+nowPlusOneDayStr);
Solution 10 - Javascript
updated:
startdate = "20.03.2014";
var new_date = moment(startdate, "DD-MM-YYYY").add(5,'days');
alert(new_date)
Solution 11 - Javascript
If you do end up running with formatting problems after adding X time to the function, try this format:
startDate = moment(startDate).add(1, "days").format("YYYY-MM-DD");
instead of:
startDate = moment(startDate, "YYYY-MM-DD").add(1, "days");
This last version keeps the time attached to the returned data, whereas the format method doesn't and literally returns YYYY-MM-DD.
