I know we use "BBY" and "ABY" to help us form a consistent continuity and timeline of events in the gffa, but what do the actual sentients(dosen't seem right to call them all "people", you know?) in the gffa use to mark their years? Sure, they could use ABY after the actual battle of yavin, however before the battle took place this could obviously not be a reference point. And even then, surely not every planet and species was aware this battle took place. And what about those species who reside in wild space, the unknown regions, or even extra galactic species like the vong? These species would be totally out of the loop with regards to the goings on in the "main parts" of the gffa (ie the rims etc.). So how would they tell what year it is? Does every species have a different way of making their years based on the rotation of their homeworld? Did all the planets/species who were mebers of the old republic use the same system to mark their years?
