What's the inaccuracy? Are you speaking of when Jesus Christ was born? At one point it was based on an estimation of that, but for a long time it has been standardized and isn't related to that anymore. There is a very specific year that is "year 1". I have a bit of an issue with it because it does seem to endorse a religion, but still.
