In brief
National Boss's Day is observed on October 16 in the United States, the date Haroski registered with the U.S. Chamber of Commerce in 1958. Hallmark and Wikipedia describe a nearest-workday shift when October 16 lands on a weekend, but the consulted founding records do not prove that clause was part of the original registration.
