There were some differences in the Julian calendar early on. I also understand that there wasn't a year zero.

Yes, the first years after the introduction of the Julian calendar applied the leap year rules differently, so the Julian calendar as we know it was not implemented before sometime between the years 4 and 8.

While there was no year zero, this is a common designation for 1 BC. Likewise 333 BC equals year –332. I think the 34s uses the same convention.
