On Venus, the calendar is a beautiful absurdity. The planet takes 243 Earth days to complete one turn on its own axis, and only 225 to complete an orbit around the Sun. The result: its day lasts longer than its year. There, you'd have a birthday before seeing a single day end.
And the disorder doesn't stop there. Venus spins the opposite way to almost every other planet: in its sky, the Sun rises in the west and sets in the east. Combining that slow, backwards spin with its journey around the Sun, a "solar day" — from one sunrise to the next — works out at about 117 Earth days. Nearly four months of thick daylight, nearly four of closed night.
Nobody knows for certain why: perhaps a colossal impact in its youth, perhaps the achingly slow brake of its dense atmosphere acting over billions of years. Earth's nearest neighbour, that evening star shining out there so calmly, is also an enormous reminder: a day and a year are not laws of the universe. They are habits of our house.
