Why is my age different on other planets?

One year is usually taken to mean an Earth year, the time taken for the Earth to revolve around the Sun. However, since each planet takes a different amount of time to revolve around the Sun, a year is not the same length of time on different planets. This means your age is different when measured in years on different planets.
