Let's assume that, without somehow reducing the influence of Christianity in other areas, this timeline does not use the terms "BC" and "AD" and instead the "current era" begins at the founding of the city of Rome in our 753 BC. What would the effects be, other than the dates of historic events, release dates of movies/games/whatever, etc?
I'm aware that there are historic events that were directly related to a certain year, but I do not know what they are. I appreciate any replies.
