Because the 20th Century is over and done with.
Think of it this way:
Pretend that when they started counting years, they called the first year ' 1 '.
And at the same time, they made up the word 'Century' to mean '100 years'.
So, ' 1 ' was the first year, ' 2 ' was the second year, ' 3 ' was the third year,
' 99 ' was the 99th year, ' 100 ' was the 100th year, and the end of the year 100
was the end of the first century.
Notice that the year 100 was the last year of Century #1, and the 2nd Century
started on January 1, 101 .
So the year 200 was the last year of Century #2, and the 3rd Century started
on January 1, 201 .
And the year 300 was the last year of Century #3, and the 4th Century started
on January 1, 401 .
Jump ahead a few centuries now . . .
The year 2000 was the last year of Century #20, and the 21st Century started
on January 1, 2001 .
2091 = twenty first century. 1991 = twentieth century. 1891 = nineteenth century. 1791 = eighteenth century. And so on.
the twenty first century beginned in 2000 because the twenty first century ends in 2100 actully

No. Right now is the twenty-first century, so 1918 is in the twentieth century. Because the year 18 is in the 1st century, 118 is in the second century, and so on.
