Here are the anniversaries
7 July 1917: Islington’s Baby Week concluded. These “Weeks” were held across the country to encourage mothers to work harder to protect the health of their children despite the hardships of wartime, amidst a growing concern about the rise in infant mortality in the capital from malnutrition and the continuing measles epidemic. Arsenal’s owner Henry Norris, was at the forefront of promoting them in London.

7 July 1998: Following the arrival of Arsene Wenger, David Platt was released from his Arsenal contract one year early. He moved to Nottingham Forest but only played five games before retiring.
