When do you think Carla's birthday is? I headcannon that her birthday is on February 11
Nice headcanon! I guess I've always thought it would be somewhere between October 1st and before March 1st (Which is a time your headcanon would fall into). Although there's nothing in the show to indicate exactly when it could be.
Side note, I've always found it a bit peculiar that the EverRealm uses the Gregorian calendar to divide it's years. I can accept that they have the same kind of moon and the same type of sun as Earth while being in a completely different solar system. And it seems like Earth has influenced the EverRealm seeing that they do have models of Earth, and there are just so many things in EverRealm culture that seem like they would have had to have come from Earth. But the fact that they would decide to split up the year in the exact same way...I don't know, it just seems noticeably weird to me for some reason (Even if their years are still 365 days long).
