Answer 1

Function that returns next weekdaay:

function getNextWeekDay (startDate, dayOfWeek){
    var dayOffset = dayOfWeek > startDate.getDay()
        ? dayOfWeek - startDate.getDay()
        : dayOfWeek - startDate.getDay() + 7;

    startDate.setDate(startDate.getDate() + dayOffset);

    return startDate;
}

var now = new Date();

var nextMonday = getNextWeekDay(new Date(),1); // 0 = Sunday, 1 = Monday, ...
var nextSaturday = getNextWeekDay(new Date(),6);
var nextSunday = getNextWeekDay(new Date(),0);
var secondNextMonday = getNextWeekDay(new Date(now.getTime() + ( 7 *24 * 60 * 60 * 1000)),1);
alert(nextMonday+ '- '+nextSaturday+ '- '+nextSunday+ '- '+secondNextMonday);

Answer 2

An even more straightforward solution is

let nextWeek = new Date()
nextWeek.setDate(nextWeek.getDate() + 7)

Note that it preserves the current time of day.

Answer 3

function nextweek(){
    var today = new Date();
    var nextweek = new Date(today.getFullYear(), today.getMonth(), today.getDate()+7);
    return nextweek;
}

Answer 4

Date.prototype.addDays = function (d) {
    if (d) {
        var t = this.getTime();
        t = t + (d * 86400000);
        this.setTime(t);
    }
};

this_week.addDays(7);

Answer 5

var firstDay = new Date("2009/06/25");
var nextWeek = new Date(firstDay.getTime() + 7 * 24 * 60 * 60 * 1000);

You can also look at DateJS if you like "fluent" APIs.

Answer 6

function dateObject.getNextWeekDay returns the next weekday after the object's own date.

Date.prototype.getNextWeekDay = function(d) {
  if (d) {
    var next = this;
    next.setDate(this.getDate() - this.getDay() + 7 + d);
    return next;
  }
}

var now = new Date();
var nextMonday = now.getNextWeekDay(1); // 0 = Sunday, 1 = Monday, ...
var secondNextMonday = new Date(nextMonday).getNextWeekDay(1);
console.log('Next Monday : ' + nextMonday);
console.log('Second Next Monday : ' + secondNextMonday);
