Forums: Index > The Wizengamot > How do people on this website know all this stuff? For example when Profesor McGonagal started Hogwarts?
- Through careful reading of the text. We know when McGonagall started at Hogwarts from OotP when Umbridge inspected her she said, "39 years this December." The year was 1995. 95-39=56. That is how we know McGonagall started in December 1956.
