Of the many dumb explanations DC Comics editors proffered to gullible young
readers to legitimatize their preposterously-powered superheroes was the one
supposedly accounting for why Superman hadn't visibly aged (as drawn by Curt
Swan and all the other Super artists ever since 1938), few were sillier than
the contention that newborn Kal-El was born to Jor-El and Kara on Krypton on
a date which corresponded to February 29th on the "Earth" calendar--by which
they imprecisely meant the Gregorian.
Superman doesn't age because comics characters generally don't.
Superman goes on a mission for President Kennedy, and fifteen years
later Superboy is shown meeting President Kennedy during a parade in
Smallville. It's comics.
There have been plenty of stories, in continuity and outside of it,
showing a middle-aged Superman. The Kingdom Come sequel showed that
he'll age into the 31st Century, and he'll look it.
The real reason for the Feb 29th birthday was because editor Mort
Weisinger didn't want to have to do a birthday story every year.
Similarly, Mxyzptlk was exiled to the 5th Dimension for 90 days at a
time so Mort wouldn't have to do a Mxy story more often than every
