Mother’s day is celebrated at different times in the year, depending on the country. For example, in the Arab World, Mother’s day is on March 21 (Spring Equinox or thereabouts), a tradition that dates back to the Pharaohs of Ancient Egypt. In many countries around the world, including the United States, Canada, Australia, Germany, Italy, Denmark, and Ghana, Mother’s Day is celebrated on the second Sunday of May.
In the United States, the origins of the official holiday go back to 1870, with the publication of The "Appeal to womanhood throughout the world" (later known as "Mothers' Day Proclamation") by Julia Ward Howe. The proclamation was a pacifist reaction to the carnage of the American Civil War and the Franco-Prussian War. The appeal was tied to Howe's feminist conviction that women had a responsibility to shape their societies at the political level.
In 1872 Howe asked for the celebration of a "Mothers' Day for Peace" on 2 June of every year, but she was unsuccessful.
In 1907, Anna Jarvis, of Philadelphia, began the campaign to have Mother’s Day officially recognized. While the day she established was different in significance from what Howe had proposed, Anna Jarvis was reportedly inspired by her mother's work with Julia Ward Howe.
In 1914, President Woodrow Wilson officially proclaimed Mother’s Day a national holiday and a “public expression of our love and reverence for all mothers.”
