How to edit the Calendar view to add extra text fields

So I am interested in adding a notification type of text field in the calendar view but I can’t seem to figure out how to edit the Calendar page.

Anyone has any idea ?

Notification type? You want to add a field in calendar view itself? Can you explain Pictorially?



So what I am thinking is to add a particular field in the calendar view itself - I want to put a history explanation of some code names that are used within the Events.

any idea
