How old is Princess Celestia

The exact number is unknown, but she has to be over 1000 years old. This is because she locked her sister away in the moon, and she got out 1000 years afterword. It is also stated that, before Luna became Nightmare Moon, they lived in peace for hundreds of years. So I believe she is over 2000 years old.

I don't remember where, but I could have sworn that the site 発言しました Celestia was a thousand years old...

I could be wrong, but...eh. *shrug* That's what I think for right now.

I remember 読書 that she is over 1000 years old, but I'm not too sure about the exact number

An infinite amount?

she is over 1000 years old

(Trolollololol)
SHE'S OVER 9000!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Well I'd think she is about like 1000000 years old becouse let's face it she was alive and the same size to stop king Sombra and she was alive when Granny Smith was just a foul

Well, to answer this question, we must put together facts. We have to think of fillyhood. And at this point, we could say she might have spent a few hundred years as a filly. So there's that. And then they say that they spent hundreds of もっと見る years together in peace. So Celestia was most likely already a couple of thousand years old before Luna was sent to the moon. So that's about 4,000 yrs old. And then when Celestia and Luna destroyed Sombra and Discord, they looked adult. So that adds on a few もっと見る thousand years. So now that's about 7,000. We come to the area when Luna is sent to the moon. So I'd say that now 9,000 yrs. And then Luna returns, so 10,000. And then we have the 2 yrs that we have so far, but that doesn't matter. So therefor, Celestia is about 10,000 yrs old. Yup, there's what I think! Hopefully my answer seems logical :3
