Notes and references
- ↑ Harry Potter and the Chamber of Secrets
- ↑ 2.0 2.1 2.2 2.3 Harry Potter and the Goblet of Fire (Chapter 1, The Riddle House), the opening chapter which takes place on August 16, 1994 states that the murders took place "fifty years before, at daybreak on a fine summer’s morning", making the year 1944. However, in Harry Potter and the Half-Blood Prince (Chapter 17, A Sluggish Memory), it is said they died "in the summer of (Tom Riddle Jr's) sixteenth year...". He was born 31 Dec 1926 and turned 16 in Dec 1942, so the summer of his sixteenth year would be 1943.
