START!
-When Shaft started making the anime version they asked me what their birthdays are. I hadn't decided, so I made something up in my reply. This was for Yuno, Miyako, Sae and Hiro.
-I forgot all about that
-Later on, on 5th of May of some year, I started seeing tweets like "Yunocchi happy birthday!"
-I had forgotten about all that so I thought they might've seen it mentioned in one of the anime art books, so I just replied with "Thank so much for celebrating her birthday!"
-Somehow Miyako, Sae and Hiro all got tweets like that too. I didn't question it and just thanked people.
-When we were planning the Aoki Ume Exhibition in Tokyo, one of the organizers asked me if they should do something since the birthdays for Madoka and Miyako seemed to be during the exhibition.
-I finally decided to check what I had replied to Shaft way back then, just to be sure.
***THE BIRTHDAYS I HAD DECIDED WERE COMPLETELY DIFFERENT FROM THE DATES PEOPLE WERE CELEBRATING THEM ON***
-Hardly anyone knows what the original dates were... so I thought it would be okay to stick with the dates most people know.
-There's a scene in the first season where Yunocchi is listening to horoscopes being read on TV, and she misses hers... even though she sees Taurus (4/20-5/20) being read.
->So the anime is inconsistent if her birthday is really on 5/5! (sweat)
