How to get next seven days from X and format in JS

Question

I want to print something like this (a 7-day calendar) but with the ability to start from any date I want.

Monday, 1 January 2011
Tuesday, 2 January 2011
Wed         


        

Answer 1

An initial date:

var startingDay = new Date(year, month, day);

A whole week from startingDay:

var thisDay = new Date();
for(var i=0; i<7; i++) {
  thisDay.setDate(startingDay.getDate() + i);
  console.log(thisDay.format());
}

The formatting function:

Date.prototype.format = function(){
    var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];        
    var days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
    return days[this.getDay()]
          +", "
          +this.getDate()
          +" "
          +months[this.getMonth()] 
          +" "
          +this.getFullYear();
};
