The Romans named their years after who was elected Consul that year. There were two Consuls, so you’d say “in the consulship of Jones and Smith”. 59BC was Julius Caesar and some other guy. The other guy was so unimportant that Romans joked by calling it the consulship of “Julius and Caesar”.
Okay, honest question: what did they call it then, if anything?
Because it’s not like they planned on counting down to the future “messiah’s” birthday.
You have to look at non-Christian calendars.
It was 2275 in Korea.
It was 265 of the 33rd dynasty in Egypt.
It was 2 of the 180th Olympiad in Greece.
