From the future perspective, yes. From the perspective of characters at the time, they wouldn't use that nomenclature, since it didn't exist yet. They would rather use the numbering system of their time (in this case, years since the establishment of Rome)
I had a thought once that no one ever lived in year one except retroactively (with some exceptions like the French Revolution). By the time a new system is adopted, it’s already been a while since the defining event.
