Mother's Day is a celebration honoring mothers and celebrating motherhood, maternal bonds, and the influence of mothers in society. It is celebrated on various days in many parts of the world, yet most commonly in March, April, or May. It complements Father's Day, the celebration honoring fathers.
Celebrations of mothers and motherhood occur throughout the world; many of these can be traced back to ancient festivals, like the Greek cult to Cybele or the Roman festival of Hilaria. The modern US holiday is not directly related to these.
Modern antecedents and foundingOne of the early calls to celebrate a Mother's Day in the United States was the "Mother's Day Proclamation" by Julia Ward Howe. Written in 1870, it was a pacifist reaction to the carnage of the American Civil War and the Franco-Prussian War. The Proclamation was tied to Howe's feminist belief that women had a responsibility to shape their societies at the political level.
Common usage in English language also dictates that the ostensibly singular possessive "Mother's Day" is the preferred spelling, although "Mothers' Day" (plural possessive) or "Mothers Day" (plural non-possessive) are sometimes used
Dates around the world
As the US holiday was adopted by other countries and cultures, the date was changed to fit already existing celebrations honouring motherhood, like Mothering Sunday in the UK or, in Greece, the Orthodox celebration of the presentation of Jesus Christ to the temple (February 2). In some countries it was changed to dates that were significant to the majority religion, like the Virgin Mary day in Catholic countries, or the birthday of the daughter of the Prophet Muhammad in Islamic countries. Other countries changed it to historical dates, like Bolivia using the date of a certain battle where women participated. See the "International history and traditions" section for the complete list.
