1900 is not the last year of 19th century. It is the first year of the twentieth century. The century starts at 0 not at 1. At the first second of 1900 you are already at 20th century even if you gave 1900 and 00 seconds to the other century for fun. The century ends at 1899.99999
The day you are born is not your zeroth year, its your first year. Your age is 0.00001 etc at that point (excluding conception age that is the true age of course) but you are at the first year of your life.
Basically this;
"The 20th century was a century that began on January 1, 1901[3] and ended on December 31, 2000." in here
https://en.wikipedia.org/wiki/20th_century is total utter bull-crap.
At some bloody point that all starts ie 00 big bang to make a point you are instantly at the first century of the universe or whatever you are not at the 0 century!
The millennium celebration took place in midnight dec 31 1999 to jan 1 2000 not in December 31 2000 01 jan 2001.
So why on earth would you label this the completion of the millennium and the start of the new one if it wasn't the end of the 20th century for example.

Basically
https://en.wikipedia.org/wiki/Gregorian_calendar got it stupidly wrong at start so we are living in 2016 actually right now but whatever since the bs started the wrong way we have to draw the line at continuing stupidity indefinitely because you do not start numbers at 1 , you start them at 0 and 0-0.999999... is the first interval...
