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.

Here's an updated fiddle

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); 

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.

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); 

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:

var end_date = moment(start_date).clone().add(5, 'days'); 

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); 

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) 

1. add to your html page
2. var todayDate = moment().format('DD-MM-YYYY');//to get today date 06/03/2018 if you want to add extra day to your current date then
3. var 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...

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); 

updated:

startdate = "20.03.2014"; var new_date = moment(startdate, "DD-MM-YYYY").add(5,'days'); alert(new_date) 

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.
