It actually lasts over 1,000 years as we go into the Roman Empire. Some of these continue and some of them don't. So for example, the notion of chariot racing does, and famously Justinian is almost overthrown after a rowdy chariot race. You don't have the Olympics. Theodosius felt that it wasn't in line with Christian tradition. But you did have things like imperial celebrations, imperial birthdays. So the Byzantine Empire definitely continued some of the traditions, but also eliminated others.
