The planets in the Solar System spin and orbit at different speeds, so their days and years are all different lengths. The following tool allows you to calculate what your age would be on another planet.

Type your date of birth (DD/MM/YYYY) and then click on a planet / /

You are Earth days old and Earth years old

This makes you:
Planet days old and
Planet years old
