NOTE: This calendar is NOT formatted for smaller screens. We are working to create a version which will work on any size device, but that’s a bit trickier than you might think with the calendar layout. Since this is a direct port from an outdated system, some of the formatting might be a bit wonky and some links might not work.
“You did do the thing properly, didn’t you?”
— Albus Dumbledore
The calendars which follow were carefully researched and are based on various references in the canon. Harry Potter was born on July 31, 1980. Therefore the events of the first chapter of this book take place on November 1, 1981, the day after Harry’s parents were killed. The second chapter takes place on a Saturday, approximately one month and one week before Harry’s 11th birthday, which is June 22, 1991. The events of chapter three take place in the week leading up to Harry’s eleventh birthday, which we know is July 31, 1991.
Unfortunately, the information in the books does not match the calendar of 1991 exactly. The book says that Harry’s birthday is on a Tuesday, while July 31, 1991, is actually on a Wednesday. To stay true to the books, we will remove a day before Harry’s birthday, place the events on the days listed, then adjust the calendar by adding a day to get things back on track.
The Official Timeline of Hogwarts (CS/dvd) was derived from this timeline. September 7 is listed on the Official Timeline as being when Harry and Ron visit Hagrid in his hut. This was an error which also appeared on this calendar until I caught the error and corrected it. The DVD timeline reproduced this error from the Lexicon timeline. However, the 7th is a Saturday, while the book states that they visited Hagrid on the afternoon of the Friday of their first week. This calendar now places that visit on Friday, September 6, which is correct. Events which are actually listed on the official timeline are indicated on this calendar in red.
The dates given on this calendar are either stated specifically in the books or can be deduced with a fair degree of certainty. Some events, such as Norbert’s arrival, are given approximately and are therefore written in blue.
