var d = new Date('2008-01-01');
d.setMonth( d.getMonth() + 1 );
alert( d.getFullYear()+'-'+(d.getMonth() + 1 ) + '-'+ d.getDate());

You can add months to your date this way.

new Date(new Date(myDate).setMonth(myDate.getMonth()+13));

Simple as that:

var myDate = new Date();
myDate.setMonth(myDate.getMonth() + 13);

Thanks. Upvoted. How to I assign `2008-01-01` to `myDate`? Tried `myDate = '2008-01-01';` but it didn't work. – guagay_wk Oct 30 '15 at 13:24
Found the answer myself. `var myDate = new Date("2008-01-01");` – guagay_wk Oct 30 '15 at 13:27

This is my own answer.

var moment = require('moment')
var myDate = new Date("2008-01-01");
myDate.setMonth(myDate.getMonth() + 13);
var answer = moment(myDate).format('YYYY-MM-DD');
