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.
Parents' Day
In 1921, Circular No. 33 designating the first Monday every December as Mothers' day was issued, as a response to the appeal Ilocos Norte Federation of Woman's Clubs. During the Philippine Commonwealth Government, then President Quezon issued Proclamation No. 213, s. 1937 declaring the day designated as Mothers' Day as Parents' Day. This was due to finding petitions to set a special date for Fathers’ Day not advisable as there are already set of numerous holidays set, and deeming it more fitting to celebrate both Mothers' and Fathers' Day together and not apart. In 1980, a proclamation was issued declaring first Sunday and the first Monday of December as Father's Day and Mother's Day respectively. In 1988, the issued presidential proclamation followed the international day of celebration of Father's and Mother's Day which most Filipinos are familiar with. However, then President Estrada tried to revive the tradition through Proclamation No. 58, s. 1998.
