π Earth wasn't always 24 hours long.
Billions of years ago, a single day on Earth lasted only about 6 hours.
As the Moon slowly moved farther away, Earth's rotation gradually slowed down.
Today, one day lasts 24 hoursβand it's still getting slightly longer, by about 1.7 milliseconds every century.
Imagine living in a world where the Sun rose and set every 6 hours!
