Parents' Day is a holiday similar to a combination of Father's Day and Mother's Day. In the United States, Parents' Day is held on the fourth Sunday of every July (in 2023 it falls on July 23). This was established in 1994 when President Bill Clinton signed a Congressional Resolution into law for "recognizing, uplifting, and supporting the role of parents in the rearing of children."
The bill was introduced by Republican Senator Trent Lott. It was supported by members of the Unification Church which also celebrates a holiday called Parents' Day, although on a different date. United States Supreme Court Justice Ruth Bader Ginsburg has said: "Replacing Mother's Day and Father's Day with a Parents' Day should be considered, as an observance more consistent with a policy of minimizing traditional sex-based differences in parental roles."
