Why Time Is Strange on Venus

On Venus, every day is your birthday, thanks to some wild planetary physics.

The planet spins backward, and so slowly that one day lasts 243 Earth days. But a year on Venus? Just 225 Earth days. So its year finishes before a single day ends. If you lived there, you’d celebrate your birthday before the sun ever set!
