Mistakes:
We know that Harry's birthday is on July 31 because that is the same day as the break in at Gringotts. From the second book we know Nearly Headless Nick's 500th Death Day Party was on 10/31/1992. Doing the math, we know that Harry's 11th Birthday was 07/31/1991. In The Sorcerer's Stone, Harry says his birthday is on a Tuesday, the day after Dudley's favorite TV show (The Great Humberto). The mistake is that July 31, 1991 fell on a Wednesday, not a Tuesday like the book said.
Dumbledore tells Harry that Lord Voldemort is the last remaining ancestor of Salazar Slytherin. But it should say that Lord Voldemort is the last remaining descendant of Salazar Slytherin.
When Tom Riddle was talking to Harry in the Chamber of Secrets he said that they were similar because they were both half bloods. But Harry isn't a half blood. Lily and James were both wizards and witches. (Many people say that because Lily was muggle born that makes Harry a half blood, but that is not true. If both parents are witches and wizards you are not a half blood. Half-blood means ONE parent is a witch/wizard and the other is a muggle.)
Laura asks, "Please tell me how the entrance to a secret chamber, built hundreds of years ago became concealed in the tap of a modern bathroom? (Chamber of Secrets)".
