On behalf of loriel_eris I ask my massive and highly SG-knowledgeable flist: What are Sam and Jack's birthdates?

Here's everything I dug up:

Daniel
(Because everything starts with Daniel.)

Daniel's birthday is July 8, as said in "Forever in a Day."

In "1969" we learn that Daniel was "about 4 and a half years old [in 1969]" (which someone needs to teach Daniel the meaning of "about") and therefore born in 1965 or 1964, making his DOB July 8, 1965 or 1964. Fanon tends to go with the 1965 year.

Sam
In "Ascension" Orlin makes a comment about Sam's birthstone being emerald which would mean her birthday is in May.

"Entity" has her birthday listed on screen as December 29, 1968. However, I very rarely trust prop references since they are often inconsistent. Does anyone know of a second source for this information or if there is a conflicting reference? (btw-this date was pulled from the StargateWiki as I'm not that good to remember Sam's birthday.)

Jack
"Fragile Balance" has a prop reference for Jack's birthday as October 20, 1952 (again, as referenced by the StargateWiki). However this is a prop reference and I'm about 80% sure that there is a conflicting prop reference in an earlier episode, though I can't remember which one. My other point of confusion is that I thought Jack was only 9 years older than Daniel (that of course could just be fanfic leaking into my brain, though).


So, learned flist, I know one of you has either done the research or remembers where to find it. What are the conflicting information and accepted answers?

Also, I'd just like to point out that this post is not about Fullmetal Alchemist and you should all thank loriel_eris for that.
