The year 2000 was the first year of the 21st century.
The year that comes after 2000 AD is 2001 AD. This marks the beginning of the new millennium, as the year 2000 was the last year of the 20th century.
The year 1976 was in the 20th Century. The 20th century ran from January 1, 1901 to December 31, 2000.
There was no year 0 AD. The first century began with year 1. One hundred years later was 100 AD. Therefore, unless the first century had only 99 years, 101 AD would have been the first year of the second century, By logical induction, the 20 century began with 1901 and lasted through 2000. The 21st century began with 2001.
1st of January 1901 to the 31st of December 2000.
The year 1984 AD falls within the 20th century. Specifically, the 20th century includes the years 1901 to 2000. Therefore, 1984 is the 84th year of that century.
The 21st century began in 2001 because the Gregorian calendar, which is the most widely used calendar system today, counts years from the year 1 AD. Since there is no year "0," the first century spanned from 1 AD to 100 AD, the second from 101 AD to 200 AD, and so forth. Consequently, the 20th century ended on December 31, 2000, and the 21st century began on January 1, 2001.
