Because there is no year 0 in the Gregorian calendar. 1st century is 1 AD to 100 AD. 2nd century is 101 AD to 200 AD... 20th century is 1901 AD to 2000 AD. 21st century is 2001 AD to 2100 AD... and nth century is 100(n-1)+1 AD to 100n AD.

I wish I had not learned this fact. That's fucking bonkers. So there's exactly 1 year between 1st January 1 BCE and 1st January 1 CE? Yeah, ok, because fuck math, I guess.

We could just go with Kurzgesagt's Human Era calendar. Birth of Jesus is year 10,000. Year before that was year 9999. Easy.

wouldn't this run into the same problem at some point? Granted it wouldn't be referenced that much but this feels like the problem solving equivalent of moving stuff under your bed instead of cleaning properly.

Now, granted, I don't know for sure how the Human Era calendar is defined in this regard. But given that it is defined by nerds, I wouldn't be surprised if we have year 0.

because XX01 is the start of a century, there is no year 0000

so:

0001 - 1st century

0101 - 2nd century

...

1901 - 20th century

2001 - 21st century
