Jack Bauer- born February 18 1966. I believe this would make him a Pisces, born in the year of the horse. 50ish when first Imported in 2010. Turning 53 this February, his third birthday in the Cityverse. 24's timeline is a bit odd: a season lasts a day, the date is never given, and years can pass in-universe between seasons. Because of that, Jack looks younger than he really is; the character has aged more than the actor. By the time of the show's eighth and final season/day, fourteen and a half in-universe years have passed since the first season/day.
Calvin- eternally six years old. Calvin is six throughout his ten-year canon, was six when brought to C&C in 2009, and remains six to this day. It's kind of odd. His birthday is never given.
Mordin Solus- hatching day unknown. Mordin's species has a shorter lifespan than humans due to their rapid metabolisms: the upper age limit is around 40, and Mordin has confirmed he's closing in on his last years of life. He's probably in his late thirties. Earth zodiac signs are of course inapplicable to him.
