The Hogwarts Board of Governors released a statement earlier today outlining some of the expected activities for the 40th anniversary of Hogwarts's rebuilding after the Battle of Hogwarts during the Second Wizarding War.
"We are looking forward to welcoming alumni back to Hogwarts on the occasion of this special anniversary. We are currently in the process of sending out invitations to alumni who would like to participate in the Career Week that we are planning for the beginning of the school year. Additionally, we are working on lining up performers for a special gala that will take place right before students leave for the holiday. We will be sharing more details as they arise."
