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.
Maternity leave in the United States
California is the first state to offer paid paternity leave weeks (six weeks, partial payment). New Jersey, Rhode Island, and New York since passed laws for paid family leave. In the rest of the US, paternity pay weeks are not offered (therefore neither paternity paid leave weeks), but fathers have access to unpaid paternity leave to care for their newborns (without new income). Often, fathers will take sick days or vacation time when they have newborns. There is also a growing number of fathers that go unpaid. Some employers are required by law to allow 12 weeks of unpaid family leave after the birth or adoption of a child. This law is under FMLA or Family Medical Leave Act. Fathers who have access to paid paternity leave give mothers the opportunity to engage in paid work, with a positive effect on female labor force participation and wages.
