What Is Age on Planets / Days Alive?

Your age in days is the number of days since your birth. Your age on other planets is your Earth age in years divided by that planet's orbital period (length of its year in Earth years). For example, a Mercury year is about 0.24 Earth years, so you would be "older" in Mercury years. This is a fun way to relate to the solar system; it has no effect on aging.
