Day-to-Day Calendar of Chamber of Secrets

Day-to-Day Calendar of Chamber of Secrets

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 Since this is a direct port from an outdated system, some of the formatting might be a bit wonky and some links may not work. 

“Very well, so you found out where the entrance was — breaking a hundred school rules into pieces along the way, I might add — but how on earth did you all get out of there alive, Potter?”
— Minerva McGonagall

The calendars which follow were carefully researched and are based on various references in the canon. The only specific reference to the year in the books is the date on Nearly Headless Nick’s Deathday cake in this book. That date, by which we can determine that book two takes place in 1992-93, has been verified by Rowling. Warner Bros. has stated that a short timeline for the series was approved by her for the release of the DVD of Chamber of Secrets. According to that Official Timeline (CS/dvd), Harry Potter was born on July 31, 1980. Therefore the events of this book begin on July 31, 1992, Harry’s 12th birthday.

Events which are specifically listed on that timeline are indicated on this calendar in red.

Curiously,Valentine’s Day in 1993 fell on a Sunday. It seems unlikely that Hogwarts holds classes on Sunday, but as Harry was on his way to Charms class when he was stopped late on Valentine’s Day afternoon by the dwarf with the singing Valentine, we’re stuck with it.
