tbh, I don't know the actual intricacies of how you make a calendar, but I've always liked the idea of separating history into eras instead of having a converging point.
this runs into problems when you consider there wouldn't be a cleat start or end date for say the bronze age, or whatever else and that these things would change depending on where geographically and historically you are talking about.
