National Nothing Day is an "un-event" proposed in 1972 by columnist Harold Pullman Coffin and observed in the United States annually on January 16 since 1973, when it was added to Chase's Calendar of Events.
[4][5][6][7] In the United States, the third Monday of every January has subsequently been inaugurated as Martin Luther King Jr. Day, which falls between the 15th and 21st.
This means that January 16 now falls on a public holiday in approximately a seventh of all years (most recently in 2023), effectively usurping the very nature of National Nothing Day.
In contrast, the Realist Society of Canada (RSC) has a religious holiday called THABS ("There has always been something," pronounced /ˈtæbs/) Day.
In 1956, the Associated Press circulated the proclamation by Mayor James W. Morgan of Birmingham, Alabama, of a "National Nothing Week" to be celebrated Saturday, February 26 through Friday, March 3 that year.
