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.
