Internal Chronology

This timeline attempts to place the events mentioned in the Girl Genius story in internal chronological order.

Methods and Assumptions

 * 1) All events below are dated relative to the attack that destroyed Castle Heterodyne.  Thus, the evening of the attack was Year 0, Day 0 (shown in green shading).  The attack occurred 407 days after Klaus Barry Heterodyne was, which would put the attack in 1873-4 or 1973-4.
 * 2) The main narrative of Girl Genius takes place roughly  after the attack on Castle Heterodyne (shown in green shading).  Thus, the story likely begins in 1892-4 or 1992-4.
 * 3) Where the narrative states a year, such as "1677", such events are placed using Klaus Barry Heterodyne's birth.  His  shows his birth year as 1_72. The second digit is round on the top and, since older dates in the crypt include 1623, is probably an 8 or 9.  Thus, he was born in either "1872" or "1972".  This is the source of the 100 year ranges in many historic dates.
 * 4) More-or-less 'certain' dates are in unshaded cells.  Dates in grey cells are best estimates.  The links lead to the source of the dating information.
 * 5) Nothing is entirely certain.  Though statements in the narrative such as "100 years ago" are given literal effect below for convenience, but they were probably only approximations and are, of course, subject to being 'clarified'.
 * 6) As an approximation, a historical event occurring "14 years before", for example, volume 7 of the story is taken to occur at the same time as an event occurring "14 years before" volume 1 of the story, since the amount of time elapsed during the story isn't terribly precise (and may never be).
