Neither Rain Nor Snow Day

National Neither Snow Nor Rain Day is certainly a mouthful and a weirdly crafted name, but its history begins at the unofficial creed of the United States Postal Service, “Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds.” The phrase’s association with the U.S. Mail originated with its inscription on New York City’s General Post Office Building, which opened in 1914. It was derived from a passage in George Herbert Palmer’s translation of Herodotus’ Histories, referring to the courier service of the ancient Persian Empire.
