Timeline of Ginger Snaps

The events of Ginger Snaps take place in October 1999, about over the course of a month.

Extrapolation
All of the dates in this timeline are extrapolated from Brigitte's calendar, acquired from a tampon box bought for Ginger. The first date which is crossed off is October 2, a full moon, also the date when Ginger was bitten by the Beast of Bailey Downs. The red circled date, October 30, is the full moon. The year 1999 was found on a missing poster for Trina Sinclair.

The dates were estimated based on time of day and transitions from scene to scene (for example, from day to night). For events where the time of day was not shown, the most probable estimate is given.

Trivia

 * The calendar exists in the Ginger Snaps universe, but not in real-life. In 1999, the only months where there were two full moons were during January and March on January 1 and 31 and March 2 and 31.  The full moon in October was on October 24.
 * Some scenes seem they take place immediately the next day, but logically they should appear several days later.
 * Interestingly, pages from Brigitte's diary from the bonus content on the CD do not appear to match up with this timeline, with entries suggesting the events of Ginger Snaps only taking place over a few days from October 28-31, but this does not match up with Brigitte's marking of her calendar.
