Thanks to Valetta's Weibo for the birthday graphic and this is a translation plus other birthday references that I realised.
Hypergryph is really stuffing the real life references from the story to archives and even the birthdays give some clues. Operator birthdays generally make references to birthdays of famous people, holidays or other historical events.
After all, this is the main lead I had on my other article about Rhine Lab being the parallel to the Manhattan Project: Because Sesa's birthday of 22 April is the same as Robert Oppenheimer, director of the Manhattan Project.
The list will be in chronological order. Feel free to comment about other references. I won't check this list, so the comments may have something too.
