What if your birthday came before your day even ended?

What if your birthday came before your day even ended? On Venus, that's not a riddle — it's just Tuesday. Venus takes around 243 Earth days to complete a single rotation. But its orbit around the Sun takes only about 225 Earth days. So the year finishes before the day does. Wrap your head around that. And there's more: Venus spins backwards relative to most planets, so if you stood on the surface, the Sun would climb over the western horizon. Not the east. The west. As for that surface — it sits at roughly 465 degrees Celsius, hotter than Mercury despite being further from the Sun. Venus plays by none of the rules.
