When the 19th century finished.
In 1901.
1999 is in the 20th Century. The first year of the 21st century is 2001.
January 1, 1901 was the turn of the 20th Century. Keep in mind that there was no official year 0. Therefore, each century starts on the first year AFTER the "00" year. Hence, the 20th century ended on December 31, 2000.
The twenty-first century started in the year 2001. As there was no "year 0" the last year of the 20th century (set of 100 years) was 2000.
the 20th century started in 1901. The first full 1900 years (19 centuries) included 1900, because there was no year 0.
From 1901 to 2001, this century was called the Twentieth century. This is because the first century did not begin in the year of Zero. It began at the year of one. Thus the first century ended on January 1, the century of one.

The 20th
There was no year designated as 'year zero'. Since a century is 100 full years, the first century went from the full year 'one' all the way through the full year 'one hundred'. The second century began on Jan 1 of the year 101. The last year of the 20th century was therefore the year 2000. The first year of the 21st century started on Jan 1, 2001. The 21st century will end Dec 31 2100.
2000 was the last year of the 20th century.
