International Women's Day Centenary
1911 - 2011
National Woman’s Day was first observed in the United States on February 28, 1909, in accordance with a declaration by the Socialist Party of America.
In 1910, at the second International Conference of Working Women held in Copenhagen, Clara Zetkin proposed that every year in every country there should be a Women’s Day celebration on the same day. Unanimously approved, International Women’s Day was established.
International Women’s Day was first observed and launched on March 19, 1911.
In 1913, International Women’s Day was transferred to March 8th and has remained the official global date to celebrate International Women’s Day since that year.
2011 commemorates the 100th Anniversary of International Women's Day.
