Ellis Island Day is observed in the United States on January 1 every year, commemorating the opening of the immigrant inspection and processing station on Ellis Island in New York Harbor in 1892. This day celebrates the historical significance of Ellis Island, where the first immigrant, Annie Moore from Ireland, entered the United States. The station processed over 400,000 immigrants in its first year and 1.5 million in its first five years. In 1992, President George H. W. Bush declared January 1 as National Ellis Island Day to mark the centennial of the station's opening, and it has since been recognized annually. People celebrate by learning about U.S. immigration history, visiting Ellis Island, researching family histories, and discussing the positive impacts of immigration on the economy. The island is now part of a national monument and is operated by the National Park Service.
