    date.setFullYear(2020,1,1);
    var _now=new Date();

    return (digits > 9) ? digits : '0' + digits;
}

The full code

var fullDate = new Date();
var twoDigitDays = twodigits(fullDate.getDate());
var twoDigitMonth = twodigits(fullDate.getMonth() + 1);

var departDate = twoDigitDays + "/" + twoDigitMonth + "/" + fullDate.getFullYear();
console.log(departDate);

fullDate.setDate(fullDate.getDate()+7);
var twoDigitDays = twodigits(fullDate.getDate());
var twoDigitMonth = twodigits(fullDate.getMonth() + 1);

var returnDate = twoDigitDays + "/" + twoDigitMonth + "/" + fullDate.getFullYear();
console.log(returnDate);

Alternate Example

var currentDate = new Date(),
currentMonth = currentDate.getMonth() + 1,
lastDayOfMonth = new Date(currentDate.getFullYear(), (currentDate.getMonth() - 1), 0).getDate(),
departureDate = futureDateDays(14),
depDate = departureDate.split('/'),
departureDateMonth = depDate[1];
if (departureDateMonth != currentMonth) {
	departureDate = leadingZero(currentMonth) + '/' + leadingZero(lastDayOfMonth) +'/'+ depDate[2];
}
console.log(departureDate);
//quick fix convert back to date using string format mm/dd/yyyy
var validDate = new Date(departureDate);
//then back to string
departureDate = leadingZero(validDate.getDate()) + '/' + leadingZero(validDate.getMonth()+1) +'/'+ validDate.getFullYear();

//Output: 
//09/31/2011
//Date {Sat Oct 01 2011 00:00:00 GMT+1000}
//01/10/2011
