To calculate the date for one day ahead you can use Date.prototype.setDate()

So to calculate all dates from today and week ahead, you can do something like this:

var currentDate = new Date();
var stringDate = [];

for (var i = 0; i < 7; ++i) {
    currentDate.setDate(currentDate.getDate() + 1);
    stringDate[i] = currentDate.getUTCDate() + "/" + (currentDate.getMonth() + 1) + "/" + currentDate.getFullYear();
}

console.log(stringDate);

// 0: "28/7/2015"
// 1: "29/7/2015"
// 2: "30/7/2015"
// 3: "31/7/2015"
// 4: "1/8/2015"
// 5: "2/8/2015"
// 6: "3/8/2015"

Just add the hours*minutes*seconds*milliseconds to today's date, and you get tomorrow's date, and so on.

var tomorrowsDate = new Date(new Date().getTime() + 24 * 60 * 60 * 1000);
