The 1800s (pronounced "eighteen-hundreds") was a decade of the Gregorian calendar that began on January 1, 1800, and ended on December 31, 1809. The term "eighteen-hundreds" can also mean the entire century from January 1, 1800 to December 31, 1899 (the years beginning with "18"), and is almost synonymous with the 19th century (1801–1900).
