Many animes give the specific dates of birth of their characters so you can tell their zodiac signs. See if you're compatible with your favorite anime character (or Otaku Doc)!
I know the dates overlap. That's what's called a cusp.
If you don't see your favorite anime character here and you have their birthdate information from a reliable source (like the Kenshin Hiden book, where I got my Rurouni Kenshin birthdate information), email it to me and I'll give you credit.
