Internal Chronology

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

Methods and Assumptions

 * 1) Sources: An attempt has been made in each event description to include a link to the source of the dating information.
 * 2) "Relative Dates": This column places events relative to two seminal events: the attack that destroyed Castle Heterodyne (which is assigned Year 0, Day 0) and the start of the main narrative of Girl Genius (which is assigned Year +19, Day 0). Clues in the narrative usually allow an event to be placed relative to one of these.
 * 3) When was the attack on Castle Heterodyne? The  for Klaus Barry Heterodyne 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. Thus, he was born in "1872". The attack occurred  after Klaus Barry Heterodyne was born, which would put the attack in 1873-4.
 * 4) When does the main narrative begin? The narrative through Volume IX takes place in the late winter/early and middle spring . The main narrative takes place roughly  after the attack on Castle Heterodyne. Thus, the story likely begins in 1892-4. This date is assumed to be +19 years, 0 days, though it could as easily be off by +/- several months.
 * 5) "Actual Dates": The Canon gives a few absolute dates, but most entries in the Actual Dates column are calculated based on clues in the narrative.
 * 6) Canonicity: 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'.
 * 7) Elapsed time: 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).
 * 8) Shading: Green highlights the attack-on-Castle-Heterodyne and start-of-narrative events. Unshaded cells hold dates that source material fixes with some precision. Grey cells hold ranges and other best estimates.

Long ago

 * 1) The other war broke out in earnest six months after Castle Heterodyne blew up.
 * 2) Bill and Barry were last seen in public helping Woggleburg after the attack on Lord Womak.

Not so long ago

 * Events start on a cold day in March.
 * Agatha is wearing her current favorite outfit, a birthday present from Lilith.
 * Assuming the castle blew up in late summer or fall and Lucrezia was pregnant at the time, Agatha's is in her nineteenth year.
 * Therefore the year is 1892.

New cues and clues from Agatha H. and the Clockwork Princess

 * 1) The Storm King Fought the Heterodynes at Sturmhalten in 1673-1676.
 * 2) The muses were all present when the treaty ending the battle was signed in 1676.
 * 3) Part of the treaty was that the Storm King would marry Bludtharst's sister Euphrosynia. They both were the offspring of Clemetious Heterodyne.
 * 4) Makes you wonder what major change happened to the castle in 1677.
