How to add number of days to today's date?

Question

I need to be able to add 1, 2 , 5 or 10 days to today's date using jQuery.

I'm a novice and trying hard to learn.

Answer 1

You can use JavaScript, no jQuery required:

var someDate = new Date();
var numberOfDaysToAdd = 6;
someDate.setDate(someDate.getDate() + numberOfDaysToAdd); 

Formatting to dd/mm/yyyy :

var dd = someDate.getDate();
var mm = someDate.getMonth() + 1;
var y = someDate.getFullYear();

var someFormattedDate = dd + '/'+ mm + '/'+ y;

Answer 2

You could extend the javascript Date object like this

Date.prototype.addDays = function(days) {
    var newDate = new Date((this.valueOf() + (days * 86400000)));
    return newDate;
};

and in your javascript code you could call

var currentDate = new Date();
// to add 4 days to current date
currentDate.addDays(4);

Answer 3

You can use this library "Datejs open-source JavaScript Date Library".

Answer 4

A suggestion: DON'T use milliseconds, or maybe daylight-saving-time will occur.
