According to http://en.wikipedia.org/wiki/Mother's_Day_(United_States)
Mother's Day holiday, in the United States and Canada, celebrates motherhood generally and the positive contributions of mothers to society. It falls on the second Sunday of each May. It is the result of a campaign by Anna Marie Jarvis (1864–1948), who, following the death of her mother on May 9, 1905, devoted her life to establishing Mother's Day as a national, and later an international, holiday. The first observances of both Mother's Day and Father's Day were held in the state of West Virginia.
"Mothering Sunday" in the UK and Ireland is on the fourth Sunday of Lent. It was originally a time when Catholics were supposed to travel to attend Mass in their "Mother Church" (the regional cathedral) rather than in their local parish. By the Reformation, it had changed into an occasion for children to visit parents. An 1854 source mentions a couplet: "On 'Mothering Sunday,' above all other/Every child should dine with its mother."[1]
"Mother's Day Work Clubs" organized by Anna Jarvis's mother, Ann Maria Reeves Jarvis (1832-1905), to improve sanitation and health in the area. These clubs also assisted both Union and Confederate encampments controlling a typhoid outbreak, and conducted a "Mothers' Friendship Day" to reconcile families divided by the Civil War.
The "Mother's Day" anti-war observances founded by Julia Ward Howe in 1872[2], it did not take root. It continued in Boston for about ten years under Howe's personal financial sponsorship, then died out.[3]
Julia Ward Howe's Mother's Day, celebrated on June 2nd, was first proclaimed around 1870 by Julia Ward Howe's Mother's Day Proclamation, and Howe called for it to be observed each year nationally in 1872. As originally envisioned, Howe's "Mother's Day" was a call for pacifism and disarmament by women. See Mother's Day Proclamation.
Early "Mother's Day" was mostly marked by women's peace groups. A common early activity was the meeting of groups of mothers whose sons had fought or died on opposite sides of the American Civil War.
The first known observance of Mother's Day in the U.S. occurred in Albion, Michigan, on May 13, 1877,[4] the second Sunday of the month. According to local legend, Albion pioneer, Juliet Calhoun Blakeley, stepped up to complete the sermon of the Rev. Myron Daughterty, who was distraught because an anti-temperance group had forced his son and two other temperance advocates to spend the night in a saloon and become publicly drunk. In the pulpit, Blakeley called on other mothers to join her. Blakeley's two sons, both travelling salesmen, were so moved that they vowed to return each year to pay tribute to her and embarked on a campaign to urge their business contacts to do likewise. At their urging, in the early 1880s, the Methodist Episcopal Church in Albion set aside the second Sunday in May to recognize the special contributions of mothers.
On February 4, 1904, South Bend, Indiana resident Frank E. Hering made the first Public Plea and started his own campaign for a national observance of "Mother's Day" in Indianapolis, Indiana.
