Forum:KB:Time

Hello, guys I got 2 questions that I desperately need an answer (its about era): 1. What year in the star wars time is the cartoon Clone Wars series now? 22 BBY? 21 BBY? 20 BBY? Or 19 BBY? And 2. What does the people in star wars (I mean the citizens of the planets...) call the years before the battle of yavin? I mean is not like they know the battle of yavin was going to happen in the future and call their year BBY and begin counting down! So what did they call it? (Though I understand the ABY part...)
