var deal_from_date = new Date();
var numberOfDaysToAdd  = 7;
 var date1 = deal_from_date.setDate(deal_from_date.getDate() + numberOfDaysToAdd);

actual Output should be

"dddd, MMMM Do YYYY, h: mm:ss a"
 Sun Oct 25 2015 12:00:00

current output is:

     Sun Oct 25 2015 12:54:06

Answer 1

setDate() method can be used to add days to a date

var today=new Date('23/10/2015');
var in_a_day=new Date(today).setDate(today.getDate()+2);

Try this code :-

var d = new Date('oct 25 2015 12:00:00 pm');
d.setDate(d.getDate() + 2)
alert(d);

output is :- Tue Oct 27 2015 12:00:00 GMT+0530 (IST)
