The idea of Father’s Day was publicly supported by President Calvin Coolidge in 1924, but was not presidentially proclaimed until 1966. It was assured of annual recognition by
PL 92-278 in April 1972.
(It’s interesting to note that in 1914 President Woodrow Wilson signed a measure officially establishing the second Sunday in May as Mother’s Day. Father’s Day became a celebration 58 years later.)
