Your Age on other Worlds by Irene Diomi

Show Your Kid How Old They Are on Jupiter, Mars With This Calculator

They say age is just a number, but it turns out that number can range wildly depending on what planet you’re on. And thanks to a nifty online calculator, you and your kid can figure out exactly how old you both would be if you were living on another planet.

Author Irene Diomi built the calculator based on NASA data and it’s extremely easy to use. All you have to do is enter the year you were born and it will tell you how old you would be if you were living on the other planets (including Pluto, which may or may not be considered a planet at this point, but who is counting anyway).
