I just remembered that there was a chapter in the light novels where the characters stated their birth dates at some point. It was the chapter where they planned to throw Kobato a birthday party so that's probably a good place start.

Also there's probably a book out there regarding personal info for each of the main characters in the series but I wasn't able to look through it. Maybe some of the past editors here have and were able to fill in the info that we see today.
