That would make her probably at least 20 years older than Sweetie Belle, though. And while that is by no means impossible, it would certainly be quite unusual.



And then we get into the issue of AJ. Presumably all the Mane Six are around the same age, so if Rarity is 34 then AJ would also be in her 30s and about 20 years older than her little sister. But then Apple Bloom wouldn't have been born yet when AJ got her cutie mark, which means her parents couldn't have been dead yet, which means they simply couldn't be bothered to go out and greet their daughter when she returned from running away from home (what jerks). And then there's "Apple Family Reunion", which implies that AJ is not that much over 200 months old, based on her hazy memories of the reunions and the fact that there are pictures of her at two previous reunions, and therefore maybe not even 20 years old.
