As we get ready to celebrate Father's Day on Sunday, here are some facts you might not know about the holiday.
The first statewide celebration of Father's Day was in 1910 in Washington. Spokane resident Sonora Smart Dod got the idea on Mother's Day in 1909, and rallied community, religious and political leaders to create a Father's Day.
Father's Day wasn't designated a federal holiday until 1972. President Richard Nixon signed Public Law 92-278 that year, making the third Sunday in June Father's Day across America.
In many Catholic countries, Father's Day lands in March. It coincides with St. Joseph's Day. St. Joseph was Jesus' earthly "father."
There are about 72 million fathers in the United States. That's according to the Census Bureau, which also says that there about 29 million grandfathers.
Yet there are only about 231,000 full-time stay-at-home dads. But that's higher than it was even a quarter-century ago.
And about 2 million dads are single parents of kids under 18. That's about 20% of all parents living with a child and no spouse or domestic partner.
Father's Day is the number-four holiday for greeting cards. About 72 million will be sold this year – or one for every dad in America. Hallmark produces 800 different designs for Father's Day.
