Father's Day is a celebration honoring fathers and celebrating fatherhood, paternal bonds, and the influence of fathers in society. Many countries celebrate it on the third Sunday of June, though it is also celebrated widely on other days by many other countries.

In 1910, a Father's Day celebration was held in Spokane, Washington, at the YMCA by Sonora Smart Dodd, who was born in Arkansas. Its first celebration was in the Spokane YMCA on June 19, 1910. Her father, the civil war veteran William Jackson Smart, was a single parent who raised his six children there.

In 1966, President Lyndon B. Johnson issued the first presidential proclamation honoring fathers, designating the third Sunday in June as Father's Day. Six years later, the day was made a permanent national holiday when President Richard Nixon signed it into law in 1972.
