Something like this :
var date = new Date('2013-02-11');
/* Add nr of days*/
date.setDate(date.getDate() + 1);
alert(date.toString());
I hope it helps.

How to add days to a date in JavaScript (without a library) - DEV Community

How to Add Days to Date in JavaScript? - GeeksforGeeks

You can create one using Date.prototype.setDate():
Date.prototype.addDays = function(days) {
var date = new Date(this.valueOf());
date.setDate(date.getDate() + days);
return date;
}
var date = new Date();
console.log(date.addDays(5));This takes care of automatically incrementing the month if necessary, as noted here. For example:
8/31 + 1 day will become 9/1.
The problem with using setDate directly is that it's a mutator and that sort of thing is best avoided. ECMA saw fit to treat Date as a mutable class rather than an immutable structure.

Correct Answer:
function addDays(date, days) {
var result = new Date(date);
result.setDate(result.getDate() + days);
return result;
}
Incorrect Answer:
This answer sometimes provides the correct result but very often returns the wrong year and month. The only time this answer works is when the date that you are adding days to happens to have the current year and month.
// Don't do it this way!
function addDaysWRONG(date, days) {
var result = new Date(); // not instatiated with date!!! DANGER
result.setDate(date.getDate() + days);
return result;
}
Proof / Example
Check this JsFiddle
// Correct
function addDays(date, days) {
var result = new Date(date);
result.setDate(result.getDate() + days);
return result;
}
// Bad Year/Month
function addDaysWRONG(date, days) {
var result = new Date();
result.setDate(date.getDate() + days);
return result;
}
// Bad during DST
function addDaysDstFail(date, days) {
var dayms = (days * 24 * 60 * 60 * 1000);
return new Date(date.getTime() + dayms);
}
// TEST
function formatDate(date) {
return (date.getMonth() + 1) + '/' + date.getDate() + '/' + date.getFullYear();
}
$('tbody tr td:first-child').each(function () {
var $in = $(this);
var $out = $('<td/>').insertAfter($in).addClass("answer");
var $outFail = $('<td/>').insertAfter($out);
var $outDstFail = $('<td/>').insertAfter($outFail);
var date = new Date($in.text());
var correctDate = formatDate(addDays(date, 1));
var failDate = formatDate(addDaysWRONG(date, 1));
var failDstDate = formatDate(addDaysDstFail(date, 1));
$out.text(correctDate);
$outFail.text(failDate);
$outDstFail.text(failDstDate);
$outFail.addClass(correctDate == failDate ? "right" : "wrong");
$outDstFail.addClass(correctDate == failDstDate ? "right" : "wrong");

You can use JavaScript, no jQuery required:
var someDate = new Date();
var numberOfDaysToAdd = 6;
var result = someDate.setDate(someDate.getDate() + numberOfDaysToAdd);
console.log(new Date(result))

This is for 5 days:
var myDate = new Date(new Date().getTime()+(5*24*60*60*1000));
You don't need JQuery, you can do it in JavaScript, Hope you get it.
