How do people on this website know all this stuff? For example when Professor McGonagall started Hogwarts? —The preceding unsigned comment was added by 126.96.36.199 (talk • contribs).
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.
J.K. Rowling has also given several interviews and press releases in which she has expanded upon the events in the books and afterwards. Most of them can be found here. - Nick O'Demus 10:15, February 5, 2010 (UTC)
Dolores Umbridge inspected all of the Professors, so therefore we know almost all of their starting dates. —The preceding unsigned comment was added by Cookieqween (talk • contribs).
