Forum:SH Archive/22 BBY vs. 21 BBY

I was looking at the pages for 22 BBY and 21 BBY, and noticed how many events from The Clone Wars are listed as taking place in 21 BBY. What is the source for this? I have several sources saying that the film took place in 22 BBY, and yet here its listed as 21 BBY. So what's the deal? Who came up with this?
