I'm not certain, but I believe all the chipmunks are the same age. I know The Chipmunks' ages were at some time revealed, though I can't say for certain of The Chipettes.
In the new tv series Jeanette has a birthday in "Jeanette Enchanted " but not Brittany and Jeanette so i would think there differnt. the boys were confurmed in the 80s but not in any other forms so it depends on what generation. In the films there in high school and the new tv show so they must all be teenagers now
Alvin mentions in Monster Madness that he has not passed the chronological age for a PG-13 film, but his physical development is at or beyond that. This suggests that in the CG series, they age at a different rate than humans, and that mental and physical maturity don't necessarily occur at the same rate. I guessed that in season one, they must be in eighth grade, as their male peers start having crushes, and their female peers have somewhat less developed hips and busts than the adult females in that universe. All we know is that the boys already knew how to talk when they met Dave about seven years before the first season. I was also wondering about the sibling age comparison as well. On the chipmunks.com profiles for the boys, Alvin and Simon are eight seconds apart in age. So, they are likely littermates. Remember that in "Sherlock Chipmunk", Theodore was celebrating his own birthday. If they don't have the same birthday, I would think that the siblings would be within a year of age of each other, as they are implied as having the same physical maturity. The Chipettes are in the same class as the boys, and so there must be no more than a year in age difference. On chipmunks.com profiles, only the age difference between Alvin and Simon is mentioned, on Simon's profile. The Chipettes are revealed to be around the same age as their male counterparts in the 80s series, as they were in the same grade and had similar mental development. But in that series, their physical maturity and rate of aging were the same as a human.
I was suspecting that the groups weren't littermates in the CG films, but were raised as siblings, and may not have a common parent. I think it's the same thing in the CG series as well.
Alvin and Brittany are the same age movie and episodes
I don't know the rest😀😀😀😀😁😁😁😁
Hello, it's not Eleanor fo today. I'm Caitlin Sparkle, most of you might recognise my name.
I may be wrong, or I could be right. To be sure that Simon is definalty older than Alvin, then Alvin was born the next day after and another next day Theodore is born. So I'm thinking they might not be triplets, but same age in the same year.
Same thing for The Chipettes. I also think that Eleanor could be older than Theodore by proving she is more mature and less childness.
