Specifically, I'm interested in Ed and Al's birthdays. Some things we know from the information given to us; their birthdays must both fall between October 2nd and February 1st. If Gracia was 5 months pregnant in October, then she would have likely given birth sometime in January, so that's when Ed's birthday must be; but what about Al's? We never see his birthday celebrated. poor Al. just because he's stuck in an animated suit of armor that doesn't age, and nobody celebrates his birthday.
So debating on this topic got me onto the subject of zodiac signs, and curious if any of them would match up with the characters.
January's signs are Capricorn and Aquarius. The description I got for those two look something like this:
Traditional Aquarian Traits - Friendly and humanitarian Honest and loyal Original and inventive Independent and intellectual
On the dark side.... Intractable and contrary Perverse and unpredictable Unemotional and detached
Traditional Capricorn Traits - Practical and prudent Ambitious and disciplined Patient and careful Humorous and reserved
On the dark side.... Pessimistic and fatalistic Miserly and grudging
Friendly, humanitarian, honest and loyal -- sounds like Al to me, so one might suggest that Al was born in the final week of January. But the Capricorn doesn't really fit with Ed -- in fact, it sounds more like Roy to me. I don't know much about zodiac personality traits. What do other people think?
