20th century

The twentieth century Anno Domini (common) era began on January 1, 1901 and ended on December 31, 2000, according to the Gregorian calendar. A common misconception is that it started in 1900 and ended in 1999, even though popular culture often reflected the correct numbering convention, such as the movie, 2001. Some historians consider the era from about 1914 to 1992 to be the Short Twentieth Century.
