The concept gained significant attention when Coolidge made his famously ambiguous statement “I do not choose to run” regarding the 1928 election. In 1959, President Eisenhower unofficially declared August 17 as Opposite Day at his granddaughter’s request, though the January 25 date eventually became the widely accepted celebration.
