Q:A question about captain America's birthday

May I ask which issue says captain America was born in 1920? I found only 1922 in The Official Handbook of the Marvel Universe: The Avengers and 1917 in The Adventures of Captain America

Cap wasn't born in 1917, that's for sure. It's 1922.

He was born on America day

Actually, he could be born in 1927

1924, I just checked
