On November 11th, 2015, /u/Airtrap commented on the fact that Superman: American Alien #1 seemed to give us the date of Superman’s birthday:
That was immensely cute, i like Kid Clark more than any adult version.
Also his “Birthday” is April the 18th, who knew
Who knew? I’d say that I should have, as the DC Multiverse Historian, but I actually didn’t – because this is the first time, I believe, that date’s been used in story continuity. That bolded bit is important, as you’ll soon see!
In this post I look at the many birthdays of Superman. In the original Reddit conversation we got a little sidetracked and I ended up covering where Smallville is located, what times of year corn grows there and, therefore, what the fields should look like when Clark’s craft crashed but as this birthday post has grown way bigger that will have to wait until a future post ;)
