February 30th – does this day exist?

I am being completely serious. Regarding the Moon, I don't know what the reason is for its distance from Earth. As for Australia, it's due to the movement of tectonic plates. I specifically mentioned Australia because I knew the approximate distance. As for the movement of the other continents, I don't know how and where they are moving, but it's a fact that they are moving.
Regarding February 30th, people should correct the calendar.
