Time Line
calendar of events:
Harry Potter and the Chamber of Secrets

"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 McGonangall

"It is our choices, Harry, that show what we truly are, far more than our abilities."
     -- Albus Dumbledore

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 is on his way to Charms class when he is stopped late on Valentine's Day afternoon by the dwarf with the singing Valentine from Ginny, we're stuck with it.
