We have a few answers about this in the FAQ that will hopefully help you:

How confident are we that the year is actually and exactly 2016? Is it possible that at some point in the last 2000 years there were any significant timekeeping mistakes?

and Did people in the Middle Ages call the year "one thousand and one" or "ten oh one"? by u/sunagainstgold

At what point did society begin referring to the year in modern terms (2012 etc)? by /u/Algernon_Asimov

And if I may add one of my own answers, about ancient Greek calendars.
