I like history very much and read different stuff when i have time. But one thing i have always wondered about and never found a real answer is what year did people from say XIV or XV (centuries are an example, as i am interested in the medieval period in general) century medieval Europe think it was at that time? Did they say for example that the current year is 1324 or did they count years differently at the time and the Gregorian calendar reformed things?
There are some previous answers in the FAQ that will hopefully help answer this question:
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 sunagainstgold
At what point did society begin referring to the year in modern terms (2012 etc)? by /u/Algernon_Asimov
Was the millennium from 999-1000 ad marked in any special way? by /u/savvysioux
Did people in 999 AD celebrate the new millennium? Were there any doomsday predictions similar to Y2K? by /u/haimoofauxerre
And a couple by me:
Did the Eastern Roman Empire date by Anno Domini or by Ab Urbe Condita?
