The agenda view shows all appointments weekly, by date. Your agenda will show all your events for that week. To view the appointments in more detail, simply click on the desired event. You can use the forwards and backward arrows at the top right corner of the screen to move from one day to another.
Notice that there is a checkbox next to each event. When checked, this signifies the completion of the event. If the box is left unchecked then the event is yet to be completed.
