Internal Chronology

From Girl Genius

Dated from the year of The Other's attack on Castle Heterodyne. All dates are approximate and probably subject to being changed.

The birth of Klaus Barry Heterodyne is 407 days before the attack. His memorial marker 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. This puts "Year 0" as 1893-4 or 1993-4 and the beginning of Agatha's adventures as likely 1892-4 or 1992-4.
