IT's a long text but you must READ IT!!!
In Episode one Edward & Alphonse had transmutated her mother on February 1910; They left & Burnt their house on October 1910 ... So far so good!!! then in the episode 6 when Edward and Alphonse was living in the house of Tucker San Glacia San gave birth Elisya right ... was the same day that Edward was in his birthday number 12 ... next in Episode 14 When Edward and Roy Mustang are about to fight .... few minutes before Maes Hughes made a reference about her daugther age that she was 3 ... you remenber that part right?
then they mean that Elisya was 1year old and Edward was 13; When Edward was 14 Elysia was 2 years old; When Elysia was 3 years old that means Edward must had 15 and in the episode where Alphonse was upset with Edward because he thought that his older brother bond fake memories on him ... Elisia was in her birthday number 4 and Edward on his Birthday number 16 ... the point is that was the year of 1911 when Edward was 12; 1912 (13) 1913 (14) 1914 (15) 1915 (16) 1916 (17) and 1917 the year the movie take place in the alchemic world Edward was 18 ... On 1915 Alphonse was 11 years old because on 1914 he went back to his body that had 10 years old so that means that on 1917 he was 13 years old ... that's right ?
Edward Elric Sure Is Aries Not Aquarium!!
I agree with someone that say that Edward is Aries and Alphonse is Piscis
because Edward act like an Arian guy (he is really stubborn) and Alphonse is calm like a Piscis guy. ;)
