**The Interplanetary Year** is a notation system for measuring time across multiple planets which have different year lengths. The notation system consists of a superscript symbol following the word 'year' in writing. Each planet is given it's own symbol to specify which planetary year is being refered to.

A planetary year is defined as the time it takes a planet to revolve around is star. The further away a planet is from its star, the longer the planet's year.
