Weekly or daily rotation of promo image slider

We have configurable length promos on site eg.. if i set 8 then on front website display 8 promo images.

Now i want to develop like rotation promos in weekly or daily basis. for eg.. if i have 24 promos and i set weekly rotation then first week display 1st 8 then second week display next 8 and so on.. and when all items done then it will display from starting.

Is it possible using circular linked list in java ? any example or any hint please ?

public class Node{
        int data;
        List<String> ids;
        Node next;
        public Node(int data,List<String> ids) {
            this.data = data;
            this.ids = ids;
        }
    }
