Although a specified timeline is not specified, the events are assumed to take place in winter of 1999 or early 2000. According to a commentary, the events of the film take place 6 months later after Ginger Snaps. This means that the events most likely take place in February or March 2000, as the location Brigitte was in was still heavily covered in snow, suggesting winter. There is no calendar as in Ginger Snaps to document specific dates, but a daily occurrence of events is recorded.
