Is Phineas Younger Than Ferb?

Phineas is 8, Ferb is 11. Candace is 15. I'm not sure how old their Друзья are, although I'm guessing Isabella is the same age as Phineas.

I heard that they were both 10 (I don't know who's older) and Canadace was 15, but in the movie Candace says that Jeremy is going to a college and a whole год older than her, which makes her 17. So I think they're 12. My cousin thinks that they grow a год every season starting a new Summer.

Nope

They are about the same age или ferb is older then phineas

after the birthday clip-o-rama Phineas is probably 11 and Ferb is still 9 and Candace is 16 and i guess Isabella is 10

i think candace is 17 which means tht Phineas and Ferb are around 10yrs old.

I think Ferb is oldest, because in one episode Candes think back on the день Phineas was born and Ferb was there and looked a little bit older, but I don't know how old they are :)

they r the same but they have diffrent birthdays and I would say that Phineas is older cus there was his birthday specail but there is not on for Freb (yet)

errrr noooo..
They're both nine.
That's what was сказал(-а) in the original pitch

I Любовь Ferb so I would say no but it doesn't matter.... well we all Любовь wht they DO!!

it says they are twins in the movie
