Father's Day
Father's Day was not celebrated in the US, outside Catholic traditions, until the 20th century. As a civic celebration in the US, it was inaugurated in the early 20th century to complement Mother's Day by celebrating fathers and male parenting.
After Anna Jarvis' successful promotion of Mother's Day in Grafton, West Virginia, the first observance of a "Father's Day" was held on July 5, 1908, in Fairmont, West Virginia, in the Williams Memorial Methodist Episcopal Church South, now known as Central United Methodist Church. Grace Golden Clayton was mourning the loss of her father, when in December 1907, the Monongah Mining Disaster in nearby Monongah killed 361 men, 250 of them fathers, leaving around a thousand fatherless children. Clayton suggested that her pastor Robert Thomas Webb honor all those fathers.
Mothering Sunday
Mothering Sunday is a holiday celebrated by Catholic and Protestant Christians in the UK and some other parts of the world. It is generally observed in parishes of the Church of England, as well as in the rest of the UK and many Anglican parishes throughout the world, especially in Canada and Australia. It falls on the fourth Sunday in Lent, exactly three weeks before Easter Day. Once observed as a day on which people would visit their "mother" church, it has become an occasion for honouring the mothers of children and giving them presents. It is increasingly being called Mother's Day, although that name properly belongs to the American holiday which is quite distinct from the original Mothering Sunday. In the UK and the Republic of Ireland, Mothering Sunday is celebrated in a similar way as Mother's Day is celebrated in the USA.
