Centuries start at the year 1, not zero. There is no year zero in our calendar, it's either 1 BC, or 1 AD, year missing in between.

There's no year 0 because back in those days nobody counted the years and centuries as we do now, it's only much later that it was decided that years and centuries would be counted the way they are so it's much later that it was decided there was a year 1 BC and 1 AD...

You are both right and wrong in the sense that the first established year (established much later as I said) is indeed the year 1 but that is mathematically speaking a mistake as any counting should start from 0.

Adding to that the fact that our calendar is known to be highly inaccurate (Jesus was not actually born in 0 or even 1, it is thought he was either born in 3 or 7 and he was certainly not born on December 25 or even January 1)

So I choose to consider the counting of years for mathematical reasons and the number 1900 is part of the 100 numbers that go from 1900 to 1999 and in that regard 1900 is part of the 20th section made of 100 units when starting to count from 0, and not the 19th section.

Which is why the 21st century began on Jan 1, 2000 and not 2001.

That sure is a lot of words to commit to something that is verifiably wrong lol... seriously, just go google "when did the 20th century start?" Feel free to disagree with the norm, but don't tell other people they're wrong heh

Look at it this way: Year one includes all days of said year, from 1/365 of a year to the final 365/365 day of that year. Thus, a century is not over until the entirety of the 100th year has actually played out. Once you've reached 1901, for instance, you are finally beginning to fill out the first year of a new century. 

To show it purely in numbers, the first year of a new century is represented by the number "1", but in reality when broken into days is actually 1/365. Thus, to change the century at 1900 would leave you with only 99 years... it is not until that 100th year has actually been completed that a full century has passed. So basically 1900 is actually 99 1/365 - 99 365/365, also known as 100.

*edit* Yikes just saw that you're still in denial... it's alright man, we all make mistakes from time to time, you don't need to bunker down and defend said mistakes. :p
