How old would I be on Mars?
Enter your age in the box above, then click the CALCULATE button to see how old you'd be on the planet Mars.
A year on Mars is longer than a year on Earth—almost twice as long at 687 days. This is roughly 1.88 times the length of a year on Earth, so to calculate your age on Mars we simply have to divide your Earth age by 1.88.
Note: Mars doesn't really have months, because the length of a month is related to the orbit of Earth's Moon. Therefore your age on Mars is shown above in decimal (to two places).
